How to provide prime functions in a program

Question

I just asked myself how to provide prime functions (check, factorizing...) in a program.
generally I see 3 opportunities:

- use the power of webservices
- use language-specific libraries
- hands-on: code yourself

what are advantages/disdvantages?

Answer 1

well making your own helper and common stuff in modules will help
you can do and code whatever you want :)
but some developers created a huge libraries that you can't even imagine the size of them so they can't be coded by someone again but you make a based project like same way in coding or same topic
I would also use sqlite if you want to make some little huge stuff here also using environment variables will help
sometimes the annoying thing is in the development Framework like kivy(crashs with external modules like is or sys)
Just Use Your Mind And Do Whatever You Want In Common Interfaces In Your Program :)
I did a helper file in my project here

Answer 2

hands on code :
- more control on what the program do and more control on resources consumed
- no need to explore ready made libraries

But :
more time to develop and more exposure to bug risk
ready made libraries:
-less time ,
- less effort
But :
-less control
