what is diffrence between number and repeat in python timeit?

Question

I can not understand the difference between number and repeat in timeit library, so would you kindly tell me what is the difference between them?

Answer 1

repeat specifies the number of samples to take.

number specifies the number of times to repeat the code for each sample.

Internally there is a loop like this:

samples = []
for _ in range(repeat):
    # start timer
    for _ in range(number):
        do_work()
    # end timer
    samples.append(duration)
