secrets can be used to generate random tokens.

#!/usr/bin/python3
import secrets
print(f"bytes   = {secrets.token_bytes(64)}")
print(f"hex     = {secrets.token_hex(64)}")
print(f"urlsafe = {secrets.token_urlsafe(64)}")

The above script should print something like this.

bytes   = b'Ji\xd95\xccN\xfeZ<\xc7\xcd\xa5\x11\x9c\x9bAE\x1e\xf2\x1b\xd7\x1cH1\xa7\xd0V\xa8\xd5\x9b\xa4\xb2N=\xd1`C\xfaK\x07\xde{k\x81\xbb=l\x0b% \xb1\xee\xf3\xdc\x11\x0b\xbeZ\x95\xa4\xb7hM\xe8'
hex     = e4d3b241b4e21fb622ec67778a8743cb0e9685352a3ffe448710473a22fdca4a130ff0072b0f4a132bd782fc885386542ba1c3db6d6445582b09d16871c2d0e5
