Struggling for first bug fix!

[Saket Harsh]

Greetings Sympy community :) 

I am a 2nd year UG at IIT Kanpur (Maths & Computing). I am currently struggling with my first bug fix. I have setup the Developmental Workflow, looked into the documentation and other stuff, installed a python debugger(as suggested by many) but I am unable to use the debugger to understand the code of sympy and debug it.

 I would be very thankful if anyone of you could take out some time to guide me for my first bug fix, as it can boost me to go further for contributing to sympy.

Thanks in advance
