Most of the code written in Python receives TLE . I think Codechef should increase Time Limit for Python users.
Here I will compare python with Java and C++
Java
Python programs are generally expected to run slower than Java programs, but they also take much less time to develop. Python programs are typically 3-5 times shorter than equivalent Java programs. This difference can be attributed to Python’s built-in high-level data types and its dynamic typing.
C++
Almost everything said for Java also applies for C++, just more so: where Python code is typically 3-5 times shorter than equivalent Java code, it is often 5-10 times shorter than equivalent C++ code! Anecdotal evidence suggests that one Python programmer can finish in two months what two C++ programmers can’t complete in a year. Python shines as a glue language, used to combine components written in C++.
For improving the performance of a python code you can refer to this page Performance Tips.
