# example of iterating a nonce in a hashing algorithm's input
import hashlib
text = "I am Satoshi Nakamoto"
for nonce in xrange(20): # iterate nonce from 0 to 19
input = text + str(nonce) # add the nonce to the end of the text
hash = hashlib.sha256(input).hexdigest() # calculate the SHA-256 hash of the input (text+nonce)
print input, '=>', hash # show the input and hash result
