Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase. Ex: If the input is:

Answer:

I am writing a Python program.

def phonebook(names, numbers):  #method phonebook that takes two parameters i.e a list of names and a list of phone numbers

   dict={}  #creates a dictionary

   for x in range(len(names)):  # loop through the names

       dict[names[x]]=numbers[x]  #maps each name to its phone number

   return dict #return dictionary in key:value form i.e. name:number

#in order to check the working of this function, provide the names and numbers list and call the function as following:

names = ['Jackie', 'Joshua', 'Marguerite']

numbers = ['404-555-1234', '678-555-5678', '770-555-9012']

print(phonebook(names, numbers))

Explanation:

The program has a function phonebook() that takes two parameters, name which is a list of names and numbers that is a list of phone numbers.

It then creates a dictionary. An empty dictionary is created using curly brackets. A dictionary A dictionary is used here to maps a names (keys) phone numbers (values) in order to create an unordered list of names and corresponding numbers.

for x in range(len(names)):  

The above statement has a for loop and two methods i.e. range() and len()

len method is used to return the length of the names and range method returns sequence of numbers just to iterate as an index and this loops keeps iterating until x exceeds the length of names.

dict[names[x]]=numbers[x]

The above statement maps each name to its phone number by mapping the first name with the first  umber, the second name with the second number and so on. This mapping is done using x which acts like an index here to map first name to first number and so on. For example dict[names[1]]=numbers[1]  will map the name (element) at 1st index of the list to the number (element) at 1st index.

return dict retursn the dictionary and the format of dictionary is key:value where key is the name and value is the corresponding number.

The screenshot of the program and its output is attached.

Answer:

Network.

Explanation:

Availability is an essential part of network security, and user behavior analysis and application analysis provide the data needed to ensure that systems are available.

Availability in computer technology ensures that systems, applications, network connectivity and data are freely available to all authorized users when they need them to perform their daily routines or tasks. In order to make network systems available regularly, it is very essential and important to ensure that all software and hardware technical conflicts are always resolved as well as regular maintenance of the systems.

A network administrator can monitor the network traffics and unusual or unknown activities on the network through the user behavior analysis and data gathered from the application analysis to ensure the effective and efficient availability of systems.

Answer:

(a) The user will be prompted to enter a different name

Explanation:

Given code;

--------------------------------------------------------------------------------------------------------

var name = prompt("Enter the name to print on your tee-shirt");

while (name.length > 12) {

name = prompt("Too long. Enter a name with fewer than 12 characters.");

}

alert("The name to be printed is " + name.toUpperCase());

--------------------------------------------------------------------------------------------------------

=>The first line of the code prompts the user to enter some name to be printed on their tee-shirt, and the input from the user is saved in a variable called name.

=> In the while block, the name variable is checked. If the length of the value of the variable is greater than 12 then a new prompt that says "Too long. Enter a name with fewer than 12 characters" is displayed.

=> In the last line, if the name variable is checked and the length is less than 12, then an alert statement showing the name in uppercase is displayed with some prepended texts.

Now, if the user enters Willy Shakespeare at the first prompt, the while block will be executed since Willy Shakespeare has over 12 characters.

In other words, the prompt in the while block, asking the user to enter a different name will be displayed. i.e

"Too long. Enter a name with fewer than 12 characters"

Answer:

num_ones = amount_to_change % 5

Explanation:

It is given that the cashier has to change the money in the maximum number of 5 dollar bills and remaining as $1 bills.

We have to write a single statement of code to assign the value to variable num_ones to find the value of $1 bills given amount_to_change.

Let us solve this by taking example:

If amount_to_change = $19

Then total number of $5 bills that can be given is 3. And amount that can be given as $5 bills is [tex]\bold{3 \times 5 = \$15}[/tex]

So, the remaining amount i.e. $19 - $15 = $4 will be given as one dollar bills.

Out of these $19, 4 bills of $1 can be found using the Modulus (%) operator.

Modulus operator leaves the remainder i.e.

Output of p % q is the remainder when a number 'p' is divided by 'q'.

19 % 5 = 4

4 is the number of one dollar bills to be given.

So, single line of code for the number of one dollar bills can be written as:

num_ones = amount_to_change % 5

Let us try it for amount_to_change  = $30

We know that 6 number of $5 bills can be used to change the amount of $30 and no one dollar bill required.

num_ones = 30 % 5 = 0 (because 30 is completely divisible by 5 so remainder is 0)

So, the correct statement is:

num_ones = amount_to_change % 5

Answer:

a. 118.20.210.254

Explanation:

Here are the few characteristics of Class A:

First bit of the first octet of class A is 0.

This class has 8 bits for network and 24 bits for hosts.

The default sub-net mask for class A IP address is 255.0.0.0

Lets see if the first bit of first octet of 118.20.210.254 address is 0.

118 in binary (8 bits) can be represented as : 1110110

To complete 8 bits add a 0 to the left.

01110110

First bit of the first octet of class A is 0 So this is class A address.

For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address

For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address

For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.

Answer:

When using find command in word we can search all of the above

Answer:

The program written in python is as follows;

import string

def easyCrypto(inputstring):

      for i in range(len(inputstring)):

             try:

                    ind = string.ascii_lowercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_lowercase[ind-1],end="")

                    else:

                           print(string.ascii_lowercase[ind+1],end="")

             except:

                    ind = string.ascii_uppercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_uppercase[ind-1],end="")

                    else:

                           print(string.ascii_uppercase[ind+1],end="")

anystring = input("Enter a string: ")

easyCrypto(anystring)

Explanation:

The first line imports the string module into the program

import string

The functipn easyCrypto() starts here

def easyCrypto(inputstring):

This line iterates through each character in the input string

      for i in range(len(inputstring)):

The try except handles the error in the program

             try:

This line gets the index of the current character (lower case)

                    ind = string.ascii_lowercase.index(inputstring[i])

This line adds 1 to the index

                    pos = ind+1

This line checks if the character is at even position

                    if pos%2 == 0:

If yes, it returns the alphabet before it

                           print(string.ascii_lowercase[ind-1],end="")

                    else:

It returns the alphabet after it, if otherwise

                           print(string.ascii_lowercase[ind+1],end="")

The except block does the same thing as the try block, but it handles uppercase letters

             except:

                    ind = string.ascii_uppercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_uppercase[ind-1],end="")

                    else:

                           print(string.ascii_uppercase[ind+1],end="")

The main starts here

This line prompts user for input

anystring = input("Enter a string: ")

This line calls the easyCrypto() function

easyCrypto(anystring)

Answer:

There is a problem in the given code in the following statement:

Problem:

punctuation = r"[.?!,;:-']"

This produces the following error:

Error:

bad character range

Fix:

The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.

So the above statement becomes:

punctuation = r"[-.?!,;:']"  

You can also do this:

punctuation = r"[.?!,;:'-]"  

You can also change this statement as:

punctuation = r"[.?!,;:\-']"

Explanation:

The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2  which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false

import re  #to use regular expressions

def compare_strings(string1, string2):  #function compare_strings that takes two strings as argument and compares them

   string1 = string1.lower().strip()  # converts the string1 characters to lowercase using lower() method and removes trailing blanks

   string2 = string2.lower().strip()  # converts the string1 characters to lowercase using lower() method and removes trailing blanks

   punctuation = r"[-.?!,;:']"  #regular expression for punctuation characters

   string1 = re.sub(punctuation, r"", string1)  # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument

   string2 = re.sub(punctuation, r"", string2)  # same as above statement but works on string2 as 3rd argument

   print('string1:',string1,'\nstring2:',string2)  #prints both the strings separated with a new line

   return string1 == string2  # compares strings and returns true if they matched else false

#function calls to test the working of the above function compare_strings

print(compare_strings("Have a Great Day!","Have a great day?")) # True

print(compare_strings("It's raining again.","its raining, again")) # True

print(compare_strings("Learn to count: 1, 2, 3.","Learn to count: one, two, three.")) # False

print(compare_strings("They found some body.","They found somebody.")) # False

The screenshot of the program along with its output is attached.

Following are the modified program to the given question:

Program Explanation:

Answer:

Since the get_seconds function is not given, I'll implement it myself;

The full program (get_seconds and main) written in python is as follows:

def  get_seconds(hour,minute,seconds):

    seconds = hour * 3600 + minute * 60 + seconds

    return seconds

time1 = get_seconds(2,30,0)

time2 = get_seconds(0,45,15)

result = time1 + time2

print(result)

Explanation:

The get_seconds defines hour, minute and seconds as its arguments

This line defines the get_seconds function

def  get_seconds(hour,minute,seconds):

This line calculates the second equivalent of the time passed to the function

    seconds = hour * 3600 + minute * 60 + seconds

This line returns the the calculated seconds equivalent of time

    return seconds

The main starts here

This line calculates the number of seconds in 2 hours and 30 minutes

time1 = get_seconds(2,30,0)

This line calculates the number of seconds in 45 minutes and 15 seconds

time2 = get_seconds(0,45,15)

This line adds both together

result = time1 + time2

This line prints the result

print(result)

Answer:

The number of execution can't always be determines

Explanation:

The following points should be noted

Variable d relies on variable x (both of double data type) for its value

d is calculated as

[tex]d = \sqrt{x}^2 - x[/tex]

Mere looking at the above expression, the value of d should be 0;

However, it doesn't work that way.

The variable x can assume two categories of values

The range of the above values depend on the system running  the application;

When variable x assumes a small value,

[tex]d = \sqrt{x}^2 - x[/tex] will definitely result in 0 and the loop will terminate immediately because [tex]\sqrt{x}^2 = x[/tex]

When variable x assumes a large value,

[tex]d = \sqrt{x}^2 - x[/tex] will not result in 0  because their will be [tex]\sqrt{x}^2 \neq x[/tex]

The reason for this that, the compiler will approximate the value of [tex]\sqrt{x}^2[/tex] and this approximation will not be equal to [tex]x[/tex]

Hence, the loop will be executed again.

Since, the range of values variable x can assume can not be predetermined, then we can conclude that the number of times the loop will be executed can't be determined.

       try:

               country_gold.append(gold[x])

       except:

               country_gold.append("Did not get gold")

Explanation:

The addition of try/except clause in the program is to let the program manage error;

In this case, the program checks for a country in the list country; This is implemented using the following line

for x in country:

If the country exists, the statement in the try block is executed

try:

 country_gold.append(gold[x])  ->This appends the country name to the country_gold list

Otherwise, the statement in the except clause is executed

except:

 country_gold.append("Did not get gold")  -> This appends "Did not get gold" to the country_gold list

To confirm what you've done, you may add the following line of code at the end of the program: print(country_gold)

Answer:

[tex]P_{10} =0.1[/tex]

Explanation:

Given

[tex]0.1, 0.1, 0.3, 0.3, 0.3, 0.4, 0.4, 0.4, 0.6, 0.7, 0.7, 0.7, 0.8, 0.8[/tex]

Required

Determine [tex]P_{10}[/tex]

[tex]P_{10}[/tex] implies 10th percentile and this is calculated as thus

[tex]P_{10} = \frac{10(n+1)}{100}[/tex]

Where n is the number of data; n = 14

[tex]P_{10} = \frac{10(n+1)}{100}[/tex]

Substitute 14 for n

[tex]P_{10} = \frac{10(14+1)}{100}[/tex]

[tex]P_{10} = \frac{10(15)}{100}[/tex]

Open the bracket

[tex]P_{10} = \frac{10 * 15}{100}[/tex]

[tex]P_{10} = \frac{150}{100}[/tex]

[tex]P_{10} = 1.5th\ item[/tex]

This means that the 1.5th item is [tex]P_{10}[/tex]

And this falls between the 1st and 2nd item and is calculated as thus;

[tex]P_{10} = 1.5th\ item[/tex]

Express 1.5 as 1 + 0.5

[tex]P_{10} = (1 +0.5)\ th\ item[/tex]

[tex]P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item[/tex]

From the given data; [tex]1st\ item = 0.1[/tex] and [tex]2nd\ item = 0.1[/tex]

[tex]P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item[/tex] becomes

[tex]P_{10} =0.1 +0.5(0.1 - 0.1)[/tex]

[tex]P_{10} =0.1 +0.5(0)[/tex]

[tex]P_{10} =0.1 +0[/tex]

[tex]P_{10} =0.1[/tex]

Answer:

Here is the python code:

StartingSal = int(input("Enter the starting salary: "))

AnnualIncrease = (int(input("Enter the annual % increase: ")) / 100)

Years = int(input("Enter the number of years: "))

for count in range(1,Years+1):  

  print("Year ", count, " Salary: ", StartingSal*((1+AnnualIncrease)**(count-1)))

Explanation:

This program prompts the user to enter starting salary, percentage increase in salary per year and number of years.

The for loop has range function which is used to specify how many times the salaries are going to be calculated for the number of years entered. It starts from 1 and ends after Years+1 means one value more than the year to display 10 too when user inputs 10 days.

The year and corresponding salary is displayed in output. At every iteration the starting salary is multiplied by annual percentage increase input by user. Here count is used to count the number of salaries per year, count-1 means it will start from 30000.
