在虚拟环境中加载空闲时设置PYTHONPATH

Question

如何设置事物，以便将PYTHONPATH设置为特定项目，并且在加载空闲后所有虚拟环境模块都可用？

Answer 1

You can append it to environment like so:

import sys
if "N:/ProjectX/Scripts" not in sys.path:
    sys.path.append("N:/ProjectX/Scripts")

Edit: you can install PyYaml package to your python with pip , then make Default_Path.yaml somewhere in your main application directory and insert your project and paths like so:

 #Paths
 ProjectX:
     Icon: 'N:/ProjectX/ICON'
     Presets: 'N:/ProjectX/Presets'
 ProjectY:
     Icon: 'N:/ProjectY/ICON'
     Presets: 'N:/ProjectY/Presets'

and to read Default_Path.yaml you can run this:

import yaml
documents = open(N:/Application/Default_Path.yaml, 'r')
doc = yaml.load(documents) #It's a Dictionary
print doc['ProjectX']['Icon']

then you can check with users system and if the path doesn't exists append them to their environment.

Edit: reading sub-python files in a python project is simply by organize and add __init__.py in every sub-folders like so:

D:/ #Driver name
    projectX/ #Project Name
        main.py #Main Application
        Mudules/ #Sub-folder
            __init__.py #initialize the sub-folder
            module1.py #package/moudle
            module2.py #package/moudle
        Widgets/ #Sub-folder
            __init__.py #initialize the sub-folder
            widget1.py #custom widget 
            widget2.py #custom widget 

visual example:

I give my main file main.py because of c++, but in python you can give any name, it's personal preference.

and to call your sub-python project in your main.py , you just write like so:

import Mudules.module1 as moudle1
import Widgets.widget1 as coolUI

or

from Mudules.module1 import *
from Widgets.widget1 import *

Then you just call you function. and you don't need to check if the path is in sys.path and if not sys.path.append() for python files.
