Python局部变量和函数

Question

mood = raw_input("Enter your mood: ").lower()
def setMood(mood):
    mood = "awesome"
    return mood
if mood != "awesome":
    setMood(mood)
    print "Yor mood is now %s!" % mood
else: print "You were awesome anyway!"

为什么返回原始输入，而不是函数中覆盖的输入？又该怎么处理呢？你知道吗

更新！！！你知道吗

解决方案：

mood = raw_input("Enter your mood: ").lower()
def setMood(mood):
    mood = "awesome"
    return mood
if mood != "awesome":
    mood = setMood(mood)
    print "Yor mood is now %s!" % mood
else: print "You were awesome anyway!"

Answer 1

外面的mood是全局的，里面的是局部的。有关更多信息，请参阅官方python文档。你知道吗
