- Caesar Cipher
Write a program that asks the user to enter a string and an integer shift value, and then encodes the string using a Caesar cipher. A Caesar cipher shifts each character in the string by the given number of positions in the alphabet. For example, with a shift of 3, "a" becomes "d", "b" becomes "e", and so on.
- Initials Formatter
Write a program that asks the user to enter a string containing multiple names separated by spaces, and then displays the initials of each name. For example, if the user enters "John William Smith Alice Mary Brown", the program should display "J. W. S. A. M. B.".
- Word Lengths Calculator
Write a program that asks the user to enter a sentence. The program should split the sentence into words and then display the length of each word. For example, if the user enters "Hello world from Python", the program should display:
Word lengths:
Hello: 5
world: 5
from: 4
Python: 6
