Python函数中如何返回多个值？（代码示例）

class Test:

    def __init__(self):

        self.str = "hello world!"

        self.x = 20  

# 返回一个对象

def fun():

    return Test()

t = fun() 

print(t.str)

print(t.x)

hello world!

20

# 返回一个列表

def fun():

    str = "hello"

    x = 20  

    return [str, x];  

list = fun() 

print(list)

['hello', 20]

# 返回一个元组

def fun():

    str = "你好！"

    x   = 2019

    return str, x;

str, x = fun() # Assign returned tuple

print(str)

print(x)

你好！

2019

# 返回一个字典

def fun():

    d = dict(); 

    d['name'] = "欧阳克"

    d['age']   = 25

    return d

d = fun() 

print(d)

{'name': '欧阳克', 'age': 25}
