Python has long provided the ability to write functions that require certain of its parameters to be passed via keyword arguments $($but not positionally$),$ but it was much more recently $($in late $2019)$ that Python incorporated the symmetric idea of arguments that can only be passed positionally $($but not via keyword$).$ When new features are added to a programming language that I$\text{'}$m familiar with, I$\text{'}$m usually motivated to want to understand why partly because I$\text{'}$m naturally curious about that sort of thing, but partly because it helps me to know when I should be considering using a new feature $($and how I might expect other members of the community, such as coworkers or open source developers, to use it$).$So$,$ let's consider the question of why Python added this particular feature. How is our ability to write a Python program improved by being able to write functions whose parameters can be specified as positional$-$only? One way to do that is to find some examples among Python's standard library where parameters are specified this way. Below is a link to the documentation for Python's standard library.Python Standard Library documentationFind three examples in three different modules, so we aren't biasing our point of view too much by finding three shades of the same color in Python's standard library where functions have at least one positional$-$only parameter defined. $($To be clear, we're talking about functions that actually use the new Python feature, not ones that simulate its behavior internally.$)$ For each one, list the function's signature as written in the documentation, such as the ones below which, notably, are not functions that specify positional$-$only parameters, so none of them would be good choices in your answer.enumerate$($iterable$,$ start $=0)$math$.$gcd$(*$integers$)$str$.$center$($width$[,$ fillchar$])$Underneath the choices you listed, briefly explain why you think the design of the functions or methods are better $($or worse$)$ for having used this feature, as opposed to allowing the same parameters to be optionally specified via keyword. $($We$\text{'}$re not asking you to write a long$-$winded answer here, so there's no need for too much analysis; the focus is on what you've deduced, in total, from the three functions you chose.$)$
