Relative import in Python
September 6, 2011

The following post is based on nosklo’s answer who explained relative imports very nicely in this thread.
Imagine the following project structure:
main.py
setup.py
app/ ->
__init__.py
package_a/ ->
__init__.py
module_a.py
package_b/ ->
__init__.py
module_b.py
Problem: how to use module_b.py from module_a.py?
Solution:
”
- you run:
python main.py main.pydoes:import app.package_a.module_amodule_a.pydoes:import app.package_b.module_b
Alternatively, 2 or 3 could use: from app.package_a import module_a
That will work as long as you have app in your PYTHONPATH. main.py could be anywhere then.”
