Frankly, sometimes it is bad to use unlimited integers in Python. Best alternative is to use NumPy fixed length types if you really need exactly 32bit or 64bit ops.

import numpy as np

v = np.uint64(99)
q = np.uint64(12) * v + np.uint64(77)

print(q)
print(type(q))

You've misinterpreted their warning. They're telling you to use a larger type than normal in order to avoid overflow issues seen with a 32-bit type. Since Python's int is essentially boundless there will never be an overflow issue.
