python-lambda是否可以有多个返回 [英] python - can lambda have more than one return
本文介绍了python-lambda是否可以有多个返回的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我知道lambda没有返回表达式.通常
I know lambda doesn't have a return expression. Normally
def one_return(a):
#logic is here
c = a + 1
return c
可以这样写:
lambda a : a + 1
如何在lambda函数中编写该代码:
How about write this one in a lambda function:
def two_returns(a, b):
# logic is here
c = a + 1
d = b * 1
return c, d
推荐答案
是的,有可能.因为这样的表达式在函数末尾:
Yes, it's possible. Because an expression such as this at the end of a function:
return a, b
等效于此:
return (a, b)
在那里,您实际上返回的是一个值:一个恰好有两个元素的元组.因此,有一个lambda返回一个元组是可以的,因为它是单个值:
And there, you're really returning a single value: a tuple which happens to have two elements. So it's ok to have a lambda return a tuple, because it's a single value:
lambda a, b: (a, b) # here the return is implicit
