In some of the problems i have done in codeforces, some algorithms which pass in c are not passing in python. As most of you know python is slower, but this should not be a problem, sometimes pypy2 is fast enough to pass the time limit, but pypy3 is still weak and is sometimes slower than python3 , so for users using python3 this is becoming a problem.

This can be solved by creating a list of factors for each language which you multiply to the time limit to make the python3 codes pass.

Eg: if time limit is 2 sec

Language	Factor	Time Limit
C/C++	1.0	2 sec
java	2.0	4 sec
python2/3/pypy3	4.0	8 sec
pypy2	2.0	4 sec

These factors are just my opinion and can be decided by the CF team, I am not asking for the exact time limits as above but just asking to consider language wise time limits.
What do you people think?

I think hackerrank uses extended time limits, do any other site use it?
Hackerrank time limits

Have anyone faced similar problems like this.
