  • What is your intended purpose?

You should be clear about the primary purpose or intent of the project you’re working on that will help in narrowing down the list of options in Python Libraries. You can also consider additional fields related to your project purpose and shrink your pool of selections further.

  • What version of Python are you using?

As there are different versions of Python available, you need to make sure that whichever version you choose for your application, it is compatible with the libraries effectively.

  • Will this library work with the other libraries you are using?

In case you are using multiple languages, you need to make sure that all the libraries work well with one another. Alternatively, working with incompatible or overlapping libraries may cause trouble than they are worth.

  • Will the library fit your budget?

Python libraries for Data Science which are available in abundance are free and in case you find that these libraries suit your project perfectly, you may not have to pay at all. However, as some libraries may require your access, you should consider the cost of the library before you proceed.
