I've been learning the python programming language over the past few weeks, and have compiled/practiced a list of Exercises that helped me solidify my programming skills and familiarize myself with the language. These exercises are only for Beginners who have just started their programming quest and want to get thier feet wet in python. The 3 Levels indicate varying degrees of increasing difficulty with respect to a Beginner.
If you would like to learn Python from scratch, I highly recommend checking out "Corey Schafer" channel on Youtube. His method of teaching is very lucid and intuitive.

Question 8 Level 2
Write a program that accepts a comma separated sequence of words as input and prints the words in a comma-separated sequence after sorting them alphabetically.
Suppose the following input is supplied to the program: without,hello,bag,world
Then, the output should be: bag,hello,without,world
Question 9 Level 2

Suppose the following input is supplied to the program:
Hello world
Practice makes perfect
Then, the output should be: HELLO WORLD PRACTICE MAKES PERFECT
Question 10 Level 2
Write a program that accepts a sequence of whitespace separated words as input and prints the words after removing all duplicate words and sorting them alphanumerically.
Suppose the following input is supplied to the program: hello world and practice makes perfect and hello world again
Then, the output should be: again and hello makes perfect practice world
Question 11 Level 2
Write a program which accepts a sequence of comma separated 4 digit binary numbers as its input and then check whether they are divisible by 5 or not. The numbers that are divisible by 5 are to be printed in a comma separated sequence.
Input: 0100,0011,1010,1001
Then the output should be: 1010
Question 12 Level 2
Write a program, which will find all such numbers between 1000 and 3000 (both included) such that each digit of the number is an even number.
The numbers obtained should be printed in a comma-separated sequence on a single line.
Question 13 Level 2
Write a program that accepts a sentence and calculate the number of letters and digits.
Suppose the following input is supplied to the program: hello world! 123
Then, the output should be:
LETTERS 10
DIGITS 3
Question 14 Level 2
Write a program that accepts a sentence and calculate the number of upper case letters and lower case letters.
Suppose the input supplied to the program is: Hello world!
Then, the output should be:
UPPER CASE 1
LOWER CASE 9
Question 15 Level 2
Write a program that computes the value of a+aa+aaa+aaaa with a given digit as the value of a.
Suppose the following input is supplied to the program: 9
Then, the output should be: 11106
Question 16 Level 2
Use a list comprehension to square each odd number in a list. The list is input by a sequence of comma-separated numbers.

Question 18 Level 3
A website requires the users to input username and password to register. Write a program to check the validity of password input by users.
Following are the criteria for checking the password:
- At least 1 letter between [a-z]
- At least 1 number between [0-9]
- At least 1 letter between [A-Z]
- At least 1 character from [$#@]
- Minimum length of transaction password: 6
- Maximum length of transaction password: 12
Your program should accept a sequence of comma separated passwords and will check them according to the above criteria. Passwords that match the criteria are to be printed, each separated by a comma.

If the following tuples are given as input to the program:
Tom,19,80
John,20,90
Jony,17,91
Jony,17,93
Json,21,85
