Python内置globals函数的详细介绍
英文文档:
globals()
Return a dictionary representing the current global symbol table. This is always the dictionary of the current module (inside a function or method, this is the module where it is defined, not the module from which it is called).
说明:
1. 返回当前作用域内全局变量的字典。
>>> globals(){'__spec__': None, '__package__': None, '__builtins__': <module>, '__name__': '__main__', '__doc__': None, '__loader__': <class>}>>> a = 1>>> globals() #多了一个a{'__spec__': None, '__package__': None, '__builtins__': <module>, 'a': 1, '__name__': '__main__', '__doc__': None, '__loader__': <class>}</class></module></class></module>
