如何从函数中获取特定值？

Question

So my question is: if I have a function that looks like this:

def function():
    x = 2 + 3
    y = x + 2
    return x, y

And I need to use an x from this function, but I don't need the y. How can I choose which value it returns.

PS. I can't change the code in the first function

Thanks for help!

Answer 1

If you can't modify the function, it will always return both. But if you're interested in only x , you can assign the output tuple to two separate variables, and essentially ignore the y argument by assigning it to an arbitrary variable and forget about it

x, _ = function()

>>> print(x)
5

Another way would be to select only the first value in the tuple:

x = function()[0]

Answer 2

for example if you need the y, you can do this:

_, y = function()

or to get x:

x, _ = function()

Answer 3

def function():
    x = 2 + 3
    y = x + 2
    return x, y

x, y = function()

print(x)

Hope that solved your problem
