Help with Python Programming Language

Hello, i am learning the Python programming language for data science. it seems a lot of times I'm learning different packages like matplotlib and then there are options for instance with what types of markers can be used for to represent data points on a figure. My question...is there a way to show all the various options for what parameters will be acceptable in a universal way. There is a lot of complex documentation out there and I'm wondering what tricks programmers use on the daily basis to help.
