Python in competitive programming

I use python to solve problems in cp for a while now.But my peers advise me to switch to c/c++ and ditch python since I have reached 3*. Is it ok if I continue to be in my comfort zone(python)? Or should i completely move and learn c/c++?or can I make use of both?

It is completely OKAY to use python . I have seen some 5*,6* using python.
Basically it totally depends on u because most online judges have cpp * 5 time limit for python so it’s not like if u are submitting in python and your code is TLE and the same code in cpp is ACC (except some case where you need to use fast I/O )
Also you can submit in Pypy .


what is pypy?
