[Solved] It only return one letter

You’re returning early in the loop, you need to build up a string and return that. Either just return a joint string or build it up

 "".join(chr(ord(s)+4) for s in pas)

def cip(pas):
    ret_val = ""
    for i in pas:
        asci = ord(i)
        encryption = asci + 4
        ret_val += chr(encryption)
    return ret_val

solved It only return one letter
