Ignore python multiple return value


Say I have a Python function that returns multiple values in a tuple:

def func():
    return 1, 2

Is there a nice way to ignore one of the results rather than just assigning to a temporary variable? Say if I was only interested in the first value, is there a better way than this:

x, temp = func()

You can use x = func()[0] to return the first value, x = func()[1] to return the second, and so on.

If you want to get multiple values at a time, use something like x, y = func()[2:4].

One common convention is to use a "_" as a variable name for the elements of the tuple you wish to ignore. For instance:

def f():
    return 1, 2, 3

_, _, x = f()
