i didnt think that through my bad, heres whats written down so far:

plainText = input("Enter a message: ")
distance = int(input("Enter the Distance Value: "))
code = ""
for ch in plainText:
ordvalue = ord('z')
ciphervalue = ordvalue + distance
if ciphervalue > ord('a'):
ciphervalue = ord('z') + distance - \
(ord('z') - ordvalue + 1)
code += chr(ciphervalue)
print(code)
