Transcribed Image Text:• Add a function atbash_wrapper()
- It should take two input parameters: input_string and method
· Within the function:
o if method =
'encrypt', use atbash_encrypt() with input_string as the
input to the function, returning, the output
o if method
'decrypt', use atbash_decrypt() with input_string as the
input to the function, returning the output
o if method is anything other than these two specific strings, the function should
return the string "Expecting method to be either 'encrypt' or 'decrypt".
• Add a test function test_atbash_wrapper()
· This test should contain at least three asserts
