Positional parameters in python

Positional parameters in python
When use Positional parameters in python 3.6

Use positional-only if names do not matter or have no meaning, and there are only a few arguments which will always be passed in the same order.

Use keyword-only when names have meaning and the function definition is more understandable by being explicit with names.

Positional-only arguments were proposed in PEP 570, and it’s worth taking a look at the doc to understand the feature in more detail.
