Recent Python versions contain a dangerous pitfall for people who use Python for solving bigint problems: https://docs.python.org/3/library/stdtypes.html#int-max-str-digits

In short, converting large integers to string raises an exception unless you explicitly raise the limit with sys.set_int_max_str_digits(1000000). Since Python is quite popular for bigint problems and this pitfall is very easy to miss, especially when you have an older version locally, I suggest mentioning it in the Python guide.
