You should not have to delete the .pyc file. The interpreter should
see that the .py file is more recent and re-compile automatically.
What is the relationship between main.py and file2.py? Probably you
need to reload file2. I think the problem is that the loaded module
has been cached, not that it is not being re-compiled. Re-launching
ipython clears the module cache. What happens if you try the above
sequence without deleting file2.pyc?
