Python - Module Not Found

Question

I am a beginner with Python. Before I start, here's my Python folder structure

-project ----src ------model --------order.py ------hello-world.py 

Under src I have a folder named model which has a Python file called order.py which contents follow:

class SellOrder(object):     def __init__(self,genericName,brandName):         self.genericName = genericName         self.brandName = brandName 

Next my hello-world.py is inside the src folder, one level above order.py:

import model.order.SellOrder  order = SellOrder("Test","Test")  print order.brandName 

Whenever I run python hello-world.py it results in the error

Traceback (most recent call last):   File "hello-world.py", line 1, in <module>     import model.order.SellOrder ImportError: No module named model.order.SellOrder 

Is there anything I missed?

Answer 1

All modules in Python have to have a certain directory structure. You can find details here.

Create an empty file called __init__.py under the model directory, such that your directory structure would look something like that:

. └── project     └── src         ├── hello-world.py         └── model             ├── __init__.py             └── order.py 

Also in your hello-world.py file change the import statement to the following:

from model.order import SellOrder 

That should fix it

P.S.: If you are placing your model directory in some other location (not in the same directory branch), you will have to modify the python path using sys.path.
