我如何通过元组元素的函数在python参数呢？ [英] How do I pass tuples elements to a function as arguments in python?

问题描述

我有一个列表，包括元组，我想每一个元组的元素传递给一个函数作为参数：

I have a list consisting of tuples, I want to pass each tuple's elements to a function as arguments:

mylist = [(a, b), (c, d), (e, f)]

myfunc(a, b)
myfunc(c, d)
myfunc(e, f)

我该怎么办呢？

此致

推荐答案

这其实是很简单的用Python，只需在列表循环做，用图示操作符（ * ），以把它解析为函数的参数：

This is actually very simple to do in Python, simply loop over the list and use the splat operator (*) to unpack the tuple as arguments for the function:

mylist = [(a, b), (c, d), (e, f)]
for args in mylist:
    myfunc(*args)

例如：

>>> numbers = [(1, 2), (3, 4), (5, 6)]
>>> for args in numbers:
...     print(*args)
... 
1 2
3 4
5 6
