Hi I need help with one of my review assignments. This is in python.

# function name: shift_cipher_decode

# inputs: string - string to encode (str)

# n - amount to shfit by (int)

# output: the decoded string

# assumptions: There can be non-alphabet characters. You must leave these alone

# Should be able to accommodate upper and lower case letters

# restrictions: DO NOT USE A DICTIONARY TO ENCODE

#YOUR LETTERS

Basically im supposed to code a decoder in a function where a print statements gives a string and a shifter. With this shifter you are supposed to move the characters of the string in ascii according to the number of shifts. For example here is an output for example this string should convert to pineapples after its conversion in ascii. However I get confused on how to analyze the string and shift it with any possible test case. If you can help me out it would be greatly appreciated

# pineapples

print(shift_cipher_decode("buzqmbbxqe", 12))
