深入了解python的函数参数

def sum(n):
    sum=0
    i=1
    while i<=n:
        sum+=i
        i+=1
    return sum
result=sum(100)
print(result)

def power(x,y=2):
    return x**y
print(power((2)))
print(power(2,3))

def printmessage(name,age,*args,gender):
    print(name,age,args,gender)
    print(type(args))
printmessage("赵四",40,12345456,"男")

def printmessage(name,age,*args,gender):
    print(name,age,args,gender)
    print(type(args))
printmessage("赵四",40,12,34,54,56,gender="男")

def printmessage(name,age,*args,gender):
    print(name,age,args,gender)
    print(type(args))
printmessage(age=45, gender='男', name='刘能')

printmessage(age=45, gender='男', name='刘能',args=(1,2,3,4))

def sumN(*args):
    # args是参数名
    # 要操作传入的参数 可以对args（相当于有参数构成的tuple）进行遍历
    print(args, type(args))
    sum = 0
    for i in args:
        sum += i
    print(sum)
sumN(1,2,3,5)

def printmessage(name,age,gender,**kw):
    print(name,age,gender,kw)
    print(type(kw))
printmessage("赵四",40,"男",address="象牙山",phonenumber="888888")
