You can use relative imports, so in mod2_file.py you could
import ..module1.mod1_file as mod1
To pull in a dependent submodule. Also, I think you are thinking about
__init__.py?
package/
__init__.py
mod1/
mod1.py
mod2/
mod2.py
And in your __init__.py you issue something like
import mod1
import mod2
if you need them loaded as soon as your package is imported, but you
may omit that and import piecemeal in your scripts as each one needs
functionality:
from mypackage.mod2 import just_this_one_function
Etc etc etc. But really if you only have a single Python file living
in each subdirectory, you are likely Doing It Wrong and your code
might just make more sense as:
package/
__init__.py
intuitively_named_submodule1.py
intuitively_named_submodule2.py
intuitively_named_submodule3.py
Where your intuitively named submodules are all logical groupings of
functionality. Remember that they don't ALL get imported right away,
in fact, only __init__.py is imported by default, so if that's missing
or doesn't import the other submodules by default, you have to
explicitly
import package.intuitively_named_submoduleN
each time you want to import a submodule.
