According to the offical documentation of timeit, I can time simple python snippets using the command line interface as follows python3 -m timeit -n 5 "'-'.join(str(n) for n in range(100))" I can also execute a python3 script named script.py by running python3 script.py Because of this I assumed I would be able to do something like this python3 -m timeit -n 5 script.py but this does not work. script.py is not a module so some suggestions along the lines of python3 -m timeit -n 5 -s 'import script(.py)' do not work either. I am a bit out of ideas how I could accomplish my goal, thus my question is Is there any good option to measure the run time of an python script using python3 -m timeit directly from the command line? Also, I do not want to do things like: using the time command in linux import the timeit module in my python script itself Already thanks for your suggestions. Continue reading...
