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