You cannot define a function! for example: after f (x) = x ^ 2 + 1 we get the error:
TypeError Traceback (most recent call last)
/usr/lib64/python3.8/codeop.py in __call __ (self, source, filename, symbol)
134
135 def __call __ (self, source, filename, symbol):
-> 136 codeob = compile (source, filename, symbol, self.flags, 1)
137 for feature in _features:
138 if codeob.co_flags & feature.compiler_flag:
TypeError: required field "type_ignores" missing from Module
