Simple and easy-to-understand PyCharm environment variable configuration guide

PyCharm is a powerful Python integrated development environment (IDE) that provides a wealth of functions and tools to help developers improve work efficiency. In PyCharm, you can easily manage the configuration information in the project by configuring environment variables. This article will introduce how to configure environment variables in PyCharm. I hope it will be helpful to beginners and developers.

1. The steps to configure environment variables in PyCharm are as follows:

1. Open your PyCharm project, right-click the project name in the project panel, and select "Edit Configurations".
2. In the pop-up window, find the configuration items that need to be configured with environment variables. Common ones include "Python Interpreter" and "Run/Debug Configurations".
3. Click on the corresponding configuration item, find the "Environment variables" section in the "Configuration" column on the right, and click the "Edit environment variables" button.
4. In the pop-up window, you can add or edit environment variables. The format of each environment variable is "variable name = variable value". Click "OK" to save the configuration.

2. Below we use an example to demonstrate how to configure environment variables in PyCharm:

Assume we have a Python project and need to use an environment named "API_KEY" Variable to store the access key of the API, we can follow the following steps to configure it:

1. Open the project in PyCharm and select "Run/Debug Configurations".
2. Click the "Edit environment variables" button in the "Environment variables" section.
3. Click the " " button in the pop-up window, add a new environment variable, the variable name is "API_KEY", the variable value is your API access key, click "OK" to save the configuration.
4. When writing Python code, you can get the value of the environment variable through os.environ.get('API_KEY'). The sample code is as follows:

import os

api_key = os.environ.get('API_KEY')
if api_key:
    print("API key is:", api_key)
else:
    print("API key is not set, please check your configuration.")

Through the above example, we can see how to configure environment variables in PyCharm, and obtain and use these environment variables in the code.

Summary: Configuring environment variables is very important in project development. It can help us manage sensitive information safely and also facilitate us to deploy and debug projects in different environments. I hope the guidelines provided in this article can help you better use PyCharm for project development.
