How can you set environment variables in PyCharm?

There are two methods to set environment variables in PyCharm: global settings and project settings.

Global settings:

1. Open PyCharm, then navigate to the “File” option in the menu bar and select “Settings”.
2. In the popup dialog box, select “Appearance & Behavior” -> “Path Variables”.
3. Click on the “+” button in the top right corner to add a new environment variable.
4. Enter the name of the environment variable, then select its value. You can choose an existing path or manually enter a path.
5. Click “OK” to save settings.

Project setup:

1. Open PyCharm and open your project.
2. Select “File” in the menu bar and then click on “Settings”.
3. In the dialog box that appears, choose “Project: [project name]” and then select “Project Interpreter”.
4. Choose the interpreter you are using from the list on the right.
5. Click on the gear icon in the top right corner and select “Show All”.
6. Select the “Environment Variables” tab in the pop-up dialog box.
7. Click the “+” button in the top right corner to add a new environment variable.
8. Enter the name of the environment variable, then choose the value of the environment variable. You can select an existing path or manually input a path.
9. Click on “OK” to save the settings.

Note: Global settings will affect all projects, while project settings will only affect the current project. If you want to use the same environment variables in multiple projects, it is recommended to use global settings.
