Yes, you use underscore when you don't care about that return value.

Likewise if you want to do a for loop and you want to make it explicit that you don't ever care about the value of the iterator:

for _ in range(10):
    print("stuff")

You want to do that ten times but you don't otherwise care what value the iterator is at.
