HOW TO: Do Relative & Absolute Imports (Python Error Explained)
To display structure of directory using tree, put
alias tree='tree.com //f'
inside ~/.bash_profile
Then run:
source ~/.bash_profile
Let’s start with this toy project structure:
The root directory contains ‘package’ which is a package because it has __init__.py
Inside package you have moduleA.py module
You also have a subpackage called ‘subpackage1’ which also has __init__.py to tell python it is part of a package.
Inside subpackage1 we have submoduleA.
Let’s look at relative imports first: let’s say in submoduleA we want to use the functions from moduleA.
We use .. to go back to a previous folder. Then import the module we want.
To run this script directly from the terminal, make sure you are running from the folder where the package is located; NOT INSIDE THE PACKAGE.
We can also do absolute imports. Let’s say in moduleA we want to use the functions from submoduleA.
We use from package.subpackage1.submoduleA import *, package here represents the top level package.
Again, to run this module directly from the terminal, make sure you are running from the folder where the package is located; NOT INSIDE THE PACKAGE.
If you want to run it interactively e.g. in Spyder. You should pip install your package in an editable state and then use absolute imports.
