None (None1)

Not to be confused with NONE, None,, nor None (Language Boi) (The real name of which is an empty string).

None is yet another nihilistic esolang invented by User:None1. It's Python, but using characters other than N, o, n and e is disallowed. Any error, including the use of forbidden characters, is silenced.

try:
    import sys

    exec(code)
except:
    pass
