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