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: All modules in Python have to have a certain directory structure. [You can
find details here.](https://docs.python.org/2/tutorial/modules.html#packages)

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.pyc
    

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`.
