[已解决]同时自定义两个函数的问题

卖糖葫芦的大婶

def happy(festival):
    print("Happy {} to you!".format(festival))
def happyB(name):
    happy()
    happy()
    print("Happy birthday ,dear{}!".format(name))
    happy()
   
这个程序我想实现，既可以自定义输入节日名称，也可以自定义输入名字。最后的效果想要这种：
Happy birthday to you!
Happy birthday to you!
Happy birthday ,dearAmy!
Happy birthday to you!
我想问一下应该怎么修改这个程序？

只需要一个函数，用默认参数可以轻松实现你的要求

1. def happy(name = 'Amy',festival = 'Birthday'):
   
2.     print("Happy %s to you!\nHappy %s to you !" % (festival, festival))
   
3.     print("Happy %s, dear %s!" % (festival, name))
   
4.     print("Happy %s to you!" % festival)
   
5. 
   
6. happy('John')
   
7. 
   
8. happy(festival = 'New Year')
   
9. 
   
10. happy('Lily', 'Thanksgiving day')

    print("Happy %s,dear %s!"%(festival,name))
    print("Happy %s to you!"% festival)

然后调用函数happy（Peter,birthday）为啥程序会报错

def happy(name ,festival):
    print("Happy %s to you!\nHappy %s to you!"%(festival,festival))
  ...

用引号括起来，传递进去的要是str
比如
happy('Peter', 'birthday')

或者先定义，再传递
name = 'Peter'
festival = 'birthday'

happy(name, festival)
