一些python 自定义函数及其调用

def hello(name):

    print("Hello "+name)

def bye():

    print("---Program is over---")

def max(a,b):

    if a>b:

        print('a',a)

    else:

        print('b',b)

def change(a):

    print("---函数内---")

    print(id(a),a)

    a=6

    print("---更改后---")

    print(id(a),a)

def change_list(a):

    a.append((100,200))

    print(id(a),a)

def fun1(a,*b):

    print(a)

    print(b)

def fun2(a,**b):

    print(a)

    print(b)

 

print('---fun1---')

fun1(3,5,6,5,4,'Dog')

print('---fun2---')

fun2(100,b=200,c=300,d='Dog',e='Elephant')

sum = lambda arg1, arg2: arg1 + arg2

print(sum(20,50))
