How to generate a "big" random number in Python?
You can use random.getrandbits():
>>> random.getrandbits(128)117169677822943856980673695456521126221LAs stated in the linked documentation, random.randrange() will also do the trick if random.getrandbits() is available.
You can also use this function to generate a number of any length.
def generateRandomNumber(digits): finalNumber = "" for i in range(digits // 16): finalNumber = finalNumber + str(math.floor(random.random() * 10000000000000000)) finalNumber = finalNumber + str(math.floor(random.random() * (10 ** (digits % 16)))) return int(finalNumber)
