What are some advanced techniques for using the timeit module in Python?

You can use the timeit module to measure execution time of small code snippets. Advanced techniques include using setup code, running multiple trials, and comparing different implementations.

Can you explain how to use setup code with timeit?

Sure! You can use the setup parameter in timeit.timeit() to define any setup code that needs to run before the timing starts. For example, if you need to import a module or create variables, you can do that in the setup.

How do I run multiple trials to get more accurate results?

You can use the number parameter in timeit.timeit() to specify how many times to execute the code snippet. Running it multiple times and averaging the results can give you a more accurate measurement.

Is there a way to compare the performance of different functions?

Yes! You can use timeit.repeat() to run multiple timing trials for different functions and compare their execution times directly.
