Why is return not working?

I am making a bitcoin miner that I will make into an ios app for people to be able to mine. Right now it is in python, why is return not working? Here is the code.

Code Block   # proof-of-work test:  hash < target      if l < target:
        print(time.asctime(), "PROOF-OF-WORK found: %064x" % (l,)
        return (nonce + 1, nonce_bin)
      else:
        print time.asctime(), "PROOF-OF-WORK false positive %064x" % (l,)
#       return (nonce + 1, nonce_bin)

Code Block # proof-of-work test: hash < target
if l < target:
print(time.asctime(), "PROOF-OF-WORK found: %064x" % (l,)
return (nonce + 1, nonce_bin)
else:
print time.asctime(), "PROOF-OF-WORK false positive %064x" % (l,)
# return (nonce + 1, nonce_bin)

It says syntax error with the arrow pointing toward the r in return but I indented right. How can I fix this? Thanks.
