Answer: D.) LEFT

Explanation: LEFT is an excel function allows users to extract a specified number of characters starting from the left. The syntax goes thus :

=LEFT(text, [num_chars])

text: the original string in which characters are to be extracted.

num_chars : takes an integer, stating the number of characters to extract.

The proper function is also an excel function which sets the first character in each word to uppercase. The mid function is also used in text extraction starting from any position in the original string based on what is specified.

The LEN function is used to get the number or length of characters in a string.

Answer:

Here is the Python code.

import csv  

inputfile = input("Enter name of the file: ")

count = {}

with open(inputfile, 'r') as csvfile:

 csvfile = csv.reader(csvfile)

 for line in csvfile:

   for words in line:

     if words not in count.keys():

       count[words] = 1

     else:

         count[words] + 1

   print(count)

Explanation:

I will explain the code line by line.

import csv   here the css is imported in order to read the file using csv.reader() method

inputfile = input("Enter name of the file: ")  This statement takes the name of the input file from the user

count = {}  this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.

with open(inputfile, 'r') as csvfile:  This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type

 csvfile = csv.reader(csvfile)  This statement uses csv.reader() method to read the csv file contents.

for line in csvfile:  This outer for loop iterates through each line of the file

for words in line:  This inner loop iterates through each word in the line

if words not in count.keys():  This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary

count[words] = 1  if the word is not present already then assign 1 to the count dictionary

co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:

hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy

Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:

{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}

But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:  

count[words] = count[words] + 1

So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:

{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}  

You can see that cat, boy, dog and hey appear twice in the file.                    

print(count) This statement prints the dictionary contents with words and their frequencies.

The program with its output is attached.

The program is an illustration of file manipulations.

File manipulations involve reading from and writing into files.

The program in Python, where comments are used to explain each line is as follows:

#This imports csv module

import csv  

#This initializes a dictionary

kounter = {}

#This gets input for the file name

fname = input("Filename: ")

#This opens and iterates through the file

with open(fname, 'r') as cfile:

   #This reads the csv file

   cfile = csv.reader(cfile)

   #This iterates through each line

   for line in cfile:

       #This iterates through each word on each line

       for words in line:

           #This counts the occurrence of each word

           if words not in kounter.keys():

               kounter[words] = 1

           else:

               kounter[words] + 1

#This prints the occurrence of each word

print(kounter)

Answer:

I am writing a Python program:

def string_type(string):

   if string=="":  //if the string is empty

       return "empty"

   elif string.count(".")>1:  #if the period sign occurs more than once in string

       if string.count("\n"):  #checks if the new line occurs in the string

           return "page"  #if both the above cases are true then its a page

       return "paragraph"  # if the period sign condition is true then its a para

   elif string.count(" ")>=1:  #if no of spaces in string occur more than once

       return "sentence"  #returns sentence

   elif len(string)==1:  # if length of the string is 1 this

       return "character"  #returns character

   else:  #if none of the above conditions is true then its a word

       return "word" #returns word

Explanation:

def string_type(string):  this is the definition of method string_type which takes a string as argument and determines whether the type of string is a word, paragraph, page, sentence or empty.

if string=="" this if condition checks if the string is empty. If this condition is true then the method returns "empty"

elif string.count(".")>1  This condition checks if the string type is a paragragh

string.count(".")>1   and if string.count("\n") both statements check if the string type is a page.

Here the count() method is used which is used to return the number of times a specified string or character appears in the given string.

Suppose the string is "Paragraphs need to have multiple sentences. It's true.\n However, two is enough. Yes, two sentences can make a paragraph."

The if condition first checks if count(".")>1 which means it counts the occurrence of period i.e. "." in the string. If the period occurs more than once this means it could be a page. But it could also be a paragraph so in order to determine the correct string type another if statement if string.count("\n") inside elif statement determines if the string is a page or not. This statement checks the number of times a new line appears in the string. So this distinguishes the string type paragraph from string type page.

elif string.count(" ")>=1: statement determines if the string is a sentence. For example if the string is "i love to eat apples." count() method counts the number of times " " space appears in the string. If the space appears more than once this means this cannot be a single word or a character and it has more than one words. So this means its a sentence.

  elif len(string)==1:  this else if condition checks the length of the string. If the length of the string is 1 this means the string only has a single character. Suppose string is "!" Then the len (string) = 1 as it only contains exclamation mark character. So the method returns "character" . If none of the above if and elif conditions evaluates to true then this means the string type is a word.

Answer:

def string_type(string):

  if string=="":  //if the string is empty

      return "empty"

  elif string.count(".")>1:  #if the period sign occurs more than once in string

      if string.count("\n"):  #checks if the new line occurs in the string

          return "page"  #if both the above cases are true then its a page

      return "paragraph"  # if the period sign condition is true then its a para

  elif string.count(" ")>=1:  #if no of spaces in string occur more than once

      return "sentence"  #returns sentence

Here are the stub functions get_user_num() and compute_avg()

def get_user_num():

   print('FIXME: Finish get_user_num()')

   return -1  

def compute_avg(user_num1, user_num2):

   print('FIXME: Finish compute_avg()')

   return -1

Explanation:

A stub is a small function or a piece of code which is sometimes used in program to test a function before its fully implemented. It can also be used for a longer program that is to be loaded later. It is also used for a long function or program that is remotely located. It is used to test or simulate the functionality of the program.  

The first stub for the function get_user_num() displays FIXME: Finish get_user_num() and then it returns -1.

The seconds stub for the function compute_avg() displays the FIXME: Finish compute_avg() and then it returns -1.

Here with each print statement, there is function name after this FIXME: Finish line. The first function name is get_user_num and the second is compute_avg().

Next the function get_user_num() is called twice and function compute_avg() followed by a print statement: print('Avg:', avg_result) which prints the result. So the program as a whole is given below:

def get_user_num():

   print('FIXME: Finish get_user_num()')

   return -1  

def compute_avg(user_num1, user_num2):

   print('FIXME: Finish compute_avg()')

   return -1  

user_num1 = 0  # the variables are initialized to 0

user_num2 = 0

avg_result = 0  

user_num1 = get_user_num()  #calls get_user_num method

user_num2 = get_user_num()

avg_result = compute_avg(user_num1, user_num2)  

print('Avg:', avg_result)

The method get_user_num() is called twice so the line FIXME: Finish get_user_num() is printed twice on the output screen. The method compute_avg() is called once in this statement avg_result = compute_avg(user_num1, user_num2)   so the line FIXME: Finish compute_avg() is printed once on the output screen. Next the statement print('Avg:', avg_result) displays Avg: -1. You can see in the above program that avg_result = compute_avg(user_num1, user_num2)   and compute_avg function returns -1 so Avg= -1. The program along with the produced outcome is attached.

In programming process, the following are important in defining what a program is to do;

i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program.  The purpose of a program should be defined in the program.

ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.

iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.

iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.

Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.
