Morning,
Got a python app I have been working on.
Currently it consits of just a couple of files but as it gets bigger I am creating more and more files and the top of my main python file I am doing
import url_thread
import task_database
import xxxx
import yyyy
and I am going to be adding another class today which is another import!
Is there a way to stick these py files into a folder, and just do import classes/*
Is there a better way I should be doing this?
More, pythonic?
yes, you can do what you are asking, but it is not advised.
you can create a package containing all your modules and then pollute your namespace by just importing everything:
from foo import *
... or a better way would be to create a nicely structured package of modules and then explicitly import them as needed.
You can make a package and import from that package: from mypackage import *.
__init__ and import from there. Also, be advised that import * has quite a few pitfalls and therefore "considered harmful" in most cases.Don't listen all the stuff people say about "namespace pollution". Go ahead and do from classes import *, if it's convenient for you (and I believe it is), but consider using __all__ in your package.
To be exact, the following folder structure would do it:
classes/
|-- class1.py
|-- class2.py
`-- __init__.py
Adding the file classes/__init__.py creates the package. It looks like this:
from class1 import Class1
from class2 import Class2
__all__ = ["Class1", "Class2"]
Please note the quotes around class names in __all__.
Then, you can use the package in whatever scripts you have:
>>> from classes import *
>>> Class1
<class classes.class1.Class1 at 0xb781c68c>
>>> Class2
<class classes.class2.Class2 at 0xb781c6ec>
>>> dir()
['Class1', 'Class2', '__builtins__', '__doc__', '__name__', '__package__']
Nice and easy.
import url_thread, task_database, xxxx, yyyyBut in general, see what people are saying below about making packages and importing tidily. Avoid usingfrom ... import *unless it's really necessary.
