本文實(shí)例講述了Python本地與全局命名空間用法。分享給大家供大家參考。具體如下：

x = 1def fun(a):  b=3  x=4  def sub(c):    d=b    global x    x = 7    print ("Nested Function/n=================")    print locals()  sub(5)  print ("/nFunction/n=================")  print locals()  print locals()["x"]  print globals()["x"]print ("/nGlobals/n=================")print globals()fun(2) ///scope.pyGlobals================={'x': 1, '__file__':'C://books//python//CH1//code//scope.py', 'fun': <function fun at 0x008D7570>, 't': <class '__main__.t'>, 'time': <module 'time' (built-in)>,. . .}Nested Function================={'c': 5, 'b': 3, 'd': 3}Function================={'a': 2, 'x': 4, 'b': 3, 'sub':  <function sub at 0x008D75F0>}47

希望本文所述對(duì)大家的Python程序設(shè)計(jì)有所幫助。
