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()
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()
You can use
x = func() to return the first value,
x = func() 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].
