Added Python Programs for bit manipulation.

Please remove the .vscode folder, or add a .gitignore file. And, instead of taking input from the user, set the numbers to the example inputs.
For example, in the check_if_ith_bit_is_set.py file, instead of

number = int(input())
index = int(input())

do

number = 5
index = 1

Do that for all files, and you're good to go.
