Write a Python program that asks the user for a string made of letters.

Let's assume that the user is well$-$behaved and does enter a string made of letters.

Your program must then print this string in four different ways:

Your program must print the string as the user entered it li$.$e$.,$ simply echo the string$)$

Your program must print an "all upper case" version of the string

Your program must print an "all lower case" version of the string

Your program must print a "capitalized" version of the string where only its first letter is in upper case and the rest of the string is in lower case letters

Finally, your program must print the number of times $"e"($or $"E")$ is found in the original string.

Requirements:

Make sure your program satisfies the Good Programming Style $($GPS$)$ described on our course web site.
