I would like to execute a script work.py in Python, after executing some initialization

  • 0

I would like to execute a script work.py in Python, after executing some initialization script init.py.

If I were looking for an interactive session, executing python -i init.py or setting PYTHONSTARTUP=/path/to/init.py would do the trick, but I am looking to execute another script.

Since this is a generic case which occurs often (init.py sets environment and so is the same all of the time), I would highly prefer not referencing init.py from work.py. How could this be done? Would anything change if I needed this from a script instead of from the prompt?

Thank you very much.

    More generally than in the accepted answer of C0deH4cker, this is discussed in the Python manual in Section 2.2.5 – Cusomization Modules. The basic idea is, to get the location of the special start-up script, one needs to execute the following Python code, e.g. from the interactive session of the interpreter:

    >>> import site
>>> site.getusersitepackages()
'/home/user/.local/lib/python3.2/site-packages'

    The output should be exactly such a location, in the file sitecustomize.py.
