When type hint is used, Python forbids checking variable types at run time

An immature idea. Python now has a type prompt, so you can provide a parameter for the Python interpreter to control whether to open the check type operation. For example, in the code, I explicitly use the type prompt, such as: # Test1.py def foo(a: str, b: str) -> str: c = None # type:str return 'hi' We can run the code with a parameter, such as python -T test1.py To prevent the Python interpreter from detecting the variable types in it, so as to improve the running speed. Thank you for reading.
