What wrong with the code?
code = input("Enter the coded text: ")
distance = int(input("Enter the distance value: "))
plainText = ""
for ch in code:
ordvalue = ord(ch)
cipherValue = ordvalue - distance
if cipherValue < ord("a"):
cipherValue = ord("z") - \
(distance - (ord("a") - ordvalue - 1))
plainText += chr(cipherValue)
print(plainText)
