Importing modules from different folder python for unknown path

Question

I have been working on a python project and I am new to it. I have made a small library for my project in which I have several different modules doing different tasks.

For example: I have 5 modules namely add, subtract, multiply, divide and root. I call all these .pyc files into my main.py file and my code runs properly if all of them are in the same folder.

Now, I want to store my main.py at: D:\project\main.py and these 5 .pyc files at : D:\project\Lib\ (In the Lib folder)

I found a solution as to mention the path of the folder Lib into the code but I can not do so as I need to submit the code somewhere and if they try to run this on their PC, it might not import these files.

What would be the possible solution to this?

• anekix: see about python packages. you need to convert a directory into a package by creating a file __init__.py in it. and then store all your modules and call it like from package.module import something
• anekix: refer my answer below
• anekix: also make sure you work with .py files instead of .pyc files. .pyc files will be generated by interprer for its internal purpose

Answer 1

Try creating a package.

Use a directory structure like this:

.
+-- main.py
+-- lib
 +-- __init__.py
 +-- add.pyc
 +-- substract.pyc
 +-- ...

Then, in your main.py file, you can import them like this:

from lib import add

More on packages on Python docs

• anekix: @BrightOne. its not good idea to use .pyc fils directly rather they are generated by the python interpreter
• Oleksii Filonenko: @anekix OP used .pyc in the examples, it's not my own decision. Nonetheless, you are right.

Answer 2

Inside D:\project\Lib create an __init__.py file. and put all your modules in D:\project\Lib now lib works as a python package.you dir structure should now look like this:

D:\project\Lib
 |
 +--- __init__.py
 +--- add.py
 +--- sub.py
 +--- multiply.py

Now from any file inside (say for ex main.py) D:\project call any module you want like this.

from Lib.add import something.

final dir structure will roughly look like this.

D:\project
 |
 +-- main.py
 +-- Lib
 |
 +--- __init__.py
 +--- add.py
 +--- sub.py
 +--- multiply.py
