In this exercise we will practice using loops to handle collections/containers. Your job is to write a program that asks the user to enter a sentence, then it counts and displays the occurrence of each letter.
Note: your program should count the letters without regard to case. For example, A and a are counted as the same.
Here is a sample run:
Enter a sentence: It's a very nice day today!
a: 3 times
c: 1 times
d: 2 times
e: 2 times
i: 2 times
n: 1 times
o: 1 times
r: 1 times
s: 1 times
t: 2 times
v: 1 times
y: 3 times
Notes:
The purpose of this problem is to practice using loops and collections/containers/strings.
Please make sure to submit a well-written program. Good identifier names, useful comments, and spacing will be some of the criteria that will be used when grading this assignment.
This assignment can be and must be solved using only the materials that have been discussed in class: loops, the index system, strings, lists and/or dictionaries. Do not look for or use alternative methods that have not been covered as part of this course.
How your program will be graded:
correctness: the program performs calculations correctly: 40%
complies with requirements (it properly uses loops, and containers/strings): 40%
code style: good variable names, comments, proper indentation and spacing : 20%
Language is python 3

Answer:

In Python:

chars = 'abcdefghijklmnopqrstuvwxyz'

letter = input("Sentence: ")

for i in range(len(chars)):

   count = 0

   for j in range(len(letter)):

       if chars[i] == letter[j].lower():

           count = count + 1

   if count > 0 :

       print(chars[i]+": "+str(count)+" times")

Explanation:

This initializes the characters of alphabet from a-z

chars = 'abcdefghijklmnopqrstuvwxyz'

This prompts the user for sentence

letter = input("Sentence: ")

This iterates through the initialized characters

for i in range(len(chars)):

This initializes count to 0

   count = 0

This iterates through the input sentence

   for j in range(len(letter)):

This compares the characters of the sentence with alphabet a-z

       if chars[i] == letter[j].lower():

If there is a match, count is incremented by 1

           count = count + 1

If there is an occurrence of character,

   if count > 0 :

The character and its count is printed

       print(chars[i]+": "+str(count)+" times")

In this exercise we have to use the knowledge of computational language in Python, so we have that code is:

It can be found in the attached image.

So, to make it easier, the code in Python can be found below:

chars = 'abcdefghijklmnopqrstuvwxyz'

letter = input("Sentence: ")

for i in range(len(chars)):

  count = 0

  for j in range(len(letter)):

      if chars[i] == letter[j].lower():

          count = count + 1

  if count > 0 :

      print(chars[i]+": "+str(count)+" times")

PROJECT: RESEARCHING THE HISTORY OF THE INTERNET
The Internet has had a profound effect on how we conduct business and our personal lives. Understanding a bit about its history is an important step to understanding how it changed the lives of people everywhere.

Using the Internet, books, and interviews with subject matter experts (with permission from your teacher), research one of the technological changes that enabled the Internet to exist as it does today. This may be something like TCP/IP, the World Wide Web, or how e-mail works. Look at what led to the change (research, social or business issues, etc.) and how that technology has advanced since it was invented.
Write a research paper of at least 2, 000 words discussing this technology. Make sure to address the technology’s development, history, and how it impacts the Internet and users today. Write in narrative prose, and include a small number of bullet points if it will help illustrate a concept. It is not necessary to use footnotes or endnotes, but make sure to cite all your sources at the end of the paper. Use at least five different sources.

Submission Requirements
Use standard English and write full phrases or sentences. Do not use texting abbreviations or other shortcuts.
Make any tables, charts, or screen shots neat and well organized.
Make the information easy to understand.

In Python!!
1. Correcting string errors
It's easy to make errors when you're trying to type strings quickly.
Don't forget to use quotes! Without quotes, you'll get a name error.
owner = DataCamp
Use the same type of quotation mark. If you start with a single quote, and end with a double quote, you'll get a syntax error.
fur_color = "blonde'
Someone at the police station made an error when filling out the final lines of Bayes' Missing Puppy Report. In this exercise, you will correct the errors.
# One or more of the following lines contains an error
# Correct it so that it runs without producing syntax errors
birthday = "2017-07-14'
case_id = 'DATACAMP!123-456?
2. Load a DataFrame
A ransom note was left at the scene of Bayes' kidnapping. Eventually, we'll want to analyze the frequency with which each letter occurs in the note, to help us identify the kidnapper. For now, we just need to load the data from ransom.csv into Python.
We'll load the data into a DataFrame, a special data type from the pandas module. It represents spreadsheet-like data (something with rows and columns).
We can create a DataFrame from a CSV (comma-separated value) file by using the function pd.read_csv.
# Import pandas
import pandas as pd
# Load the 'ransom.csv' into a DataFrame
r = ___.___('___')
# Display DataFrae
print(r)
3. Correcting a function error
The code in the script editor should plot information from the DataFrame that we loaded in the previous exercise.
However, there is an error in function syntax. Remember that common function errors include:
Forgetting closing parenthesis
Forgetting commas between each argument
Note that all arguments to the functions are correct. The problem is in the function syntax.
# One or more of the following lines contains an error
# Correct it so that it runs without producing syntax errors
# Plot a graph
plt.plot(x_values y_values)
# Display the graph
plt.show()
4. Snooping for suspects
We need to narrow down the list of suspects for the kidnapping of Bayes. Once we have a list of suspects, we'll ask them for writing samples and compare them to the ransom note.
A witness to the crime noticed a green truck leaving the scene of the crime whose license plate began with 'FRQ'. We'll use this information to search for some suspects.
As a detective, you have access to a special function called lookup_plate.
lookup_plate accepts one positional argument: A string representing a license plate.
# Define plate to represent a plate beginning with FRQ
# Use * to represent the missing four letters

Given three subroutines of 550, 290, and 600 words each, if segmentation is used then the total memory needed is the sum of the three sizes (if all three routines are loaded). However, if paging is used, then some storage space is lost because subroutines rarely fill the last page completely, and that results in internal fragmentation. Determine the total amount of wasted memory due to internal fragmentation when the three subroutines are loaded into memory using each of the following page sizes:
a. 100 words
b. 600 words
c. 700 words
d. 900 words

Count operation Lucky twos
Lucky Twos determines and displays the number of digits that are 2s in a whole number. For example, the number of 2s in 3487 is 0, while the number of 2s in 272521 is 3. Note: whole numbers are non-negative integers starting at zero 0, 1, 2, 3, 4.
Assume that the fractional part is discarded in the division:
10 / 4 = 2
8 / 5 = 1
20 / 3 = 6
Read number

while number > 0
If the number module 10 is Then add
