Python：如何将2D列表中项目的索引分配给两个整数变量？

Question

So I found out how to find the indexes of an item in a 2D list in Python by using this code:

def index_2d(myList, v):
    for i, x in enumerate(myList):
        if v in x:
            return (i, x.index(v))

Usage:

index_2d(myList, 3)
#Result (1, 0)

I want the output to be in two variables (like x = 1, y = 0). How can I do this?

Answer 1

In Python, you can return more than one value using tuples.

def f():
    return (1,2,3)

(x, y, z) = f()

In a more pythonic way to do it, you can only separate the values with ',' to indicate that it is a tuple.

x, y, z = f()
