Have you ever used underscore ( _ ) to denote unused arguments in a function or method?

In Python, the underscore _ symbol is often used to denote variables or arguments that will not be used further in the code.

For example, if a function takes several arguments but some of them are not needed, _ can be used to ignore these values:

def process_data(_, important_value, __):
    print(important_value)

process_data(10, 20, 30)  # Will output: 20

Here, _ and __ are argument names that signal to other developers that these values are not important and are not used.

This helps make the code cleaner and more understandable, especially when working with functions that return tuples where only some of the values are needed.
