Hey @sshniro,
Upgrading the Python version seems to solve the issue. Hence, try upgrading your Python to v3.5.3 or above. The minimum requirement for it to run needs python v3.5.3 or above.
Furthermore, Glitch doesn’t seem to support Python projects. Thus, I can’t say that latest version of Python will be added or not, since Glitch was not originally made to support Python.
Check out the Suggestions about upgrading Python to latest version on Glitch.
Hope it helps!
