I've been having trouble finding the error for this code after many tries, but I just can't seem to find the error. Can somebody help me out?

Answer 1

Line 12 parentheses missing.

Should be like this:

mode = input().lower()

Method getKey is wrongly indented.

Should be like this:

def getKey():
key = 0
while True:
print('Enter the key number (1-%s)' % (MAX_KEY_SIZE))
key = int(input())
if (key >= 1 and key <= MAX_KEY_SIZE):
return key

line 31 to 33 also wrongly indented.

Should be like this:

if mode[0] == 'd':
key = -key
translated = ''

After that, your code runs, but it will still not do what you want.

Can you find the problem?
