在前面我们讲解了 [Python][Python 2] 内置函数 locals ，[内置函数 locals][locals] 直接以字典的形式返回当前位置的所有局部变量，今天需要介绍的是另外一个 Python 内置函数 [globals][] ，**该函数直接以[字典 dict][dict] 的形式返回当前位置的所有全局变量；**

## 一.Python globals 函数语法 ##

# 返回值：返回一个字典，该字典包含当前位置的所有全局变量；
    
    globals()

## 二.Python globals 函数使用 ##

# !usr/bin/env python
    # -*- coding:utf-8 _*-

    """
    
    x = 1
    
    def func():
         c = 1
         d = 2
         return False
    
    if __name__ == "__main__":
         a = 1
         b = 2
         func()
         print(globals())
    
    '''
    输出结果：
    
    {'__name__': '__main__', '__doc__': None, '__package__': None, '__loader__': <_frozen_importlib_external.SourceFileLoader object at 0x00000199AFAFD0F0>, '__spec__': None, '__annotations__': {}, '__builtins__': <module 'builtins' (built-in)>, '__file__': 'E:/Project/python/python_project/untitled10/123.py', '__cached__': None, 'x': 1, 'func': <function func at 0x00000199ADEE2EA0>, 'a': 1, 'b': 2}
