relative import for python33

I was trying to do some coding practice with python. And here's my structure

mydir/
  template.py
  problem1/
    solution.py
  problem2/
    solution.py

I'd like to write some general-used staff in template.py and import them in solution.py in both problem1 and problem2 and maybe the problems afterwards.

What should I do to make this possible. I was once trying to do this in solution.py

from .. import template

but it failed.

This is kind of a touchy thing for Python. What you are trying to do with template.py is more apt for a second package for common stuff. Just put MyDev on your PYTHONPATH.

So I think you would have a better time with:

MyDev/
  common/
    myutils.py
  solutions/
    solution1.py
    solution2.py

And in solution1:

from common.myutils import awesome_func

And this may explain as to why it is not working for you:

How to do relative imports in Python?

PEP8 also has some good style guidelines for using imports. Basically, in my own words, unless you are developing a large package for the community where complexity is neccesesary and imports start to get overly verbose absolute imports are the way to go.

A good example of a code base that does use relative imports is SQLAlchemy.

You might do the following: import sys and then: sys.path.append('../') If you import template now, it should work.
