python function access to main variable

Question

I know this is a stupid question, but it's happening on my side.

def func():
    print(name)


if __name__ == "__main__":
    name = "halo"
    print(name)

    func()

As I know, func( ) can't see name variable. But its showing "halo" twice.

I am working in PyCharm. Any suggestion? Or python originally works in this way?

func can see the name variable. It is a global variable, because the place where you created it is not inside any class or function. All functions can read global variables.

@cogito I think you are looking for the word "scope" or "variable scope" here. – tobias_k Feb 01 '19 at 13:51
