Best way to load module from sub directory?
Is this the recommended way to load a module from a sub directory?
import imp a, b ,c = imp.find_module('fruit') imp.load_module(' ', a, b, c) import fruit fruit.apple()
I have also noticed other examples changing the home directory instead
import sys sys.path[0:0] = '/folder1' import fruit
I like to put an
__init__file in my folder that imports all the modules in the folder, then use it like a module (
from directory import file)
In the beta, the Documents folder is no longer on the sys.path, nor is '.' so I don't think the init trick works anymore.
The folder that you run a script from gets inserted to the top of sys.path, but I think this might work differently when running from the action menu.
You should probably use sys.path.insert rather than sys.path=, maybe like
if somepath not in sys.path: sys.path.insert(somepath,0)
Ok cool. I have also been reloading the modules at runtime because they do not reflect my changes unless I kill Pythonista and rerun.
import fruit fruit = reload(fruit)
If you have the beta, you also have pythonista_startup.py to take some corrective action if you need to.
This problem will also be corrected in the 2.0 (the beta automatically unloads modules not in site packages, so they get reloaded automatically). Note it is not necessary to have a left hand side to the reload statement
import fruit reload(fruit)
__init__trick works fine in the beta, I use it all the time. Relative imports most certainly do work in the beta, @omz has explained recently that
.in sys.path has been replaced by the full path to the directory, which is effectively the same. Although it was removed in one beta, it was put back in, this was a mistake .
It works in a script - because the absolute path of the script gets added-- but not in the console unless you have run a script there first. sys.path is also reset when you press play or use the action menu.
If mostly you run scripts, from the play button or action menu, you are all good. But this can be confusing when you are debugging in the console, since typed in imports might not work as expected!
