Is there a way to restart or reset the python interpreter as part of the python doctrine?

Question

I am writing a short tutorial and would like to be able to run examples in it using python doctest using

python -m doctest foo.txt

There is a point in the tutorial where I want to start using a new, clean python interpreter. Is there a mechanism for this?

Answer 1

If you only want to run the new python interpreter inside the python interpreter, you can simply execute the command: os.system ('python')
