How do I set up parameters for the timeit module in Python?

To set up parameters for the timeit module, you can use the timeit.timeit() function, which takes a statement to execute and the number of times to execute it.

Can you give me an example of how to use it with a custom function?

Sure! You can define a function and then pass it as a statement. For example:

import timeit

def my_function():
    return sum(range(100))

execution_time = timeit.timeit('my_function()', globals=globals(), number=1000)
print(execution_time)

What does the number parameter do?

The number parameter specifies how many times the statement will be executed. This helps in measuring the average execution time.

Is there a way to set up a timer for a specific setup code?

Yes! You can use the setup parameter to define any setup code that needs to run before the main statement. For example:

timer = timeit.Timer('my_function()', setup='from __main__ import my_function')
execution_time = timer.timeit(number=1000)
