python返回多个值与赋值多个值的示例代码

def min_max(list1):
    # 这样直接返回多个值是返回元组
    # 所以是不是可以想做无论是接收值和返回值，默认是看做元组的
    # 所以无论是返回值和赋值都可以这样操作
    return min(list1),max(list1)

>>> t1 = ('a', 'b', 'c')
>>> temp = t1
>>> t2 = t1
>>> t1 = temp

>>> t1, t2 = t2, t1

>>> t1, t2 = 1, 2, 3
Traceback (most recent call last):

>>> addr = 'mondy@163.com'
>>> uname, domain = addr.split('@')

>>> uname

'mondy'

>>> domain

'163.com'

>>> t = divmod(8, 5)

>>> t

(1, 3)

>>> quot, rem = divmod(8, 5)
>>> quot
1
>>> rem
3

>>> def min_max(t):
...     return min(t), max(t)
... 
>>> t = (10, 20, 30, 40)
>>> print(min_max(t))
(10, 40)
