/usr/lib/python3.8/codeop.py in __call__(self, source, filename, symbol)
    131
    132     def __call__(self, source, filename, symbol):
--> 133         codeob = compile(source, filename, symbol, self.flags, 1)
    134         for feature in _features:
    135             if codeob.co_flags & feature.compiler_flag:
