With the environ dictionary variable value of the environment variable can be set by passing the key in the dictionary and assigning the value to it. With setdefault a default value can be assigned to the environment variable. Bypassing the key and the default value in the setdefault method.
On the Windows taskbar, right-click the Windows icon and select System. In the Settings window, under Related Settings, click Advanced system settings. On the Advanced tab, click Environment Variables. Click New to create a new environment variable.
PyCharm allows you to inspect variables in a dedicated dialog. This is useful when you need to keep track of some variable (or the object whose reference it holds) and at the same time be able to navigate between frames and threads. Right-click a variable on the Variables tab and select Inspect.
You can set environmental variables in Pycharm's run configurations menu.
Open the Run Configuration selector in the top-right and cick Edit Configurations...
Find Environmental variables and click ...
Add or change variables, then click OK
You can access your environmental variables with os.environ
import os
print(os.environ['SOME_VAR'])
I was able to figure out this using a PyCharm plugin called EnvFile. This plugin, basically allows setting environment variables to run configurations from one or multiple files.
The installation is pretty simple:
Preferences > Plugins > Browse repositories... > Search for "Env File" > Install Plugin.
Then, I created a file, in my project root, called environment.env which contains:
DATABASE_URL=postgres://127.0.0.1:5432/my_db_name
DEBUG=1
Then I went to Run->Edit Configurations, and I followed the steps in the next image:
In 3, I chose the file environment.env, and then I could just click the play button in PyCharm, and everything worked like a charm.
This functionality has been added to the IDE now (working Pycharm 2018.3)
Just click the EnvFile tab in the run configuration, click Enable EnvFile and click the + icon to add an env file
Update: Essentially the same as the answer by @imguelvargasf but the the plugin was enabled by default for me.
This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.
Do pip install python-dotenv in your environment (the same as being pointed to by pycharm).
Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console
In "starting script" include something like this near the top:
from dotenv import load_dotenv load_dotenv(verbose=True)
The .env file can look like this:
export KEY=VALUE
It doesn't matter if one includes export or not for dotenv to read it.
As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.
None of the above methods worked for me. If you are on Windows, try this on PyCharm terminal:
setx YOUR_VAR "VALUE"
You can access it in your scripts using os.environ['YOUR_VAR'].
In the Pycharm Python console just type
ENV_VAR_NAME="STRING VARIABLE"
INT_VAR_NAME=5
Unlike other Python text editors, you do not add export in Pycharm
