Sequence subtraction

[Tbot]

So, this is the final code:

errorlevel = 0
errors = 0
r1 = raw_input("Commands:")
word = 'sdddwwx'
for i in range(min(len(r1), len(word))):
    if r1[i] != word[i]:
        errors += 1
if errorlevel >= errors or errors == 0:
    print"Good!"
else:
    print errors

Thank you for your help.
