This code is a simple encryption function that takes a given string and a key as inputs. It then uses a loop to iterate through the characters of the message one by one. For each character, it adds the key to its ASCII value, resulting in a new character that is shifted by the key number of letters in the alphabet. The resulting encrypted message is then returned.
Given the following code, explain what it does in layman’s terms.
def encrypt(message, key):
  encrypted_message = ""
  for i in range(len(message)):
    encrypted_message += chr(ord(message[i]) + key)
 
  return encrypted_message
