函数的参数数量不确定时，可以使用*args 和**kwargs，*args 没有key值，**kwargs有key值。

这样说吧：这个是Python函数可变参数args及kwargs *args表示任何多个无名参数，它是一个tuple **kwargs表示关键字参数，它是一个dict

示例:

def highschool_class(number,*args):

 print("the highschool_class  has %s "%number)  #高中一个班级的人数    
 print(*args)    
 return (args)  

highschool_class(59,30,29)

结果：

the highschool_class has 59
30 29

Process finished with exit code 0

def highschool_class(number,*args,**kwargs): print(“the highschool_class has %s “%number) #高中一个班级的人数 print(args)
print(kwargs)
return (args,kwargs)

highschool_class(59,30,29,male = ’30’,female = ’29’)

结果：

the highschool_class has 59
30 29
{‘male’: ’30’, ‘female’: ’29’}

Process finished with exit code 0
