in proof_of_work I am having trouble checking the difficulty of the hash to make sure I have the right nonce. my code looks like this

def proof_of_work(self,block, difficulty=2):
proof = block.generate_hash()
while difficulty * ‘0’ != proof[difficulty:]:
block.nonce += 1
proof = block.generate_hash()
block.nonce = 0

block.nonce = 0
should be outside the while loop and the two lines before that indented
