Python內置函數(26)——globals

英文文檔：

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).

說明：

　　1. 返回當前作用域內全局變數的字典。

>>> globals()
{'__spec__': None, '__package__': None, '__builtins__': <module 'builtins' (built-in)>, '__name__': '__main__', '__doc__': None, '__loader__': <class '_frozen_importlib.BuiltinImporter'>}
>>> a = 1
>>> globals() #多了一個a
{'__spec__': None, '__package__': None, '__builtins__': <module 'builtins' (built-in)>, 'a': 1, '__name__': '__main__', '__doc__': None, '__loader__': <class '_frozen_importlib.BuiltinImporter'>}
