THIS IS THE REFERENCE QUESTION AND CODE I WROTE:

Let's continue the process!

Make functionatbash_encrypt()that takes a string as its input and returns the reverse alphabetical string as its output (the same task as Q2...just turning it into a function).

Remember that functions have their own namespace, so you'll likely want to redefinealphaandreverse_alphain your function directly.

def atbash_encrypt(input_string):

alpha = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

reverse_alpha = 'ZYXWVUTSRQPONMLKJIHGFEDCBA'

#creating a reverse string

reverse_string= ""

#looping through all characters in the input string

for char in input_string:

if char.upper() in alpha:

index= alpha.find(char.upper())

reverse_string += reverse_alpha[index]

else:

#if the upper case of any character is not in alpha, return None

return None

return reverse_string

THIS IS THE QUESTION AT HAND:

Make test functiontest_atbash_encrypt()that:

1. contains at least three asserts that test the functionality ofatbash_encrypt()
2. passes silently when executed
