问题
I have written 2 functions doing the exact same thing, but I don't know which one is faster and better. How do I compare these 2 functions to see which one is better in terms of performance and everything?
回答1:
The timeit module will do ya.
回答2:
Once you've found out which function is faster using the timeit module, you can also get more precise details of where the differences are by using the profile module.
