How to configure Python environment variables

Methods to configure Python environment variables: 1. Install Python; 2. Find the Python installation path; 3. Open system properties; 4. Configure system environment variables; 5. Verify environment variable configuration; 6. Configure user environment variable.

#Python is a popular programming language that is widely used in fields such as software development, data analysis, and scientific computing. After installing Python, we need to configure the environment variables so that the Python executable file can be accessed from any location. This article will introduce how to configure Python environment variables to facilitate smooth use of Python programming.

Step One: Install Python

First, we need to install Python on the computer. The latest version of Python can be downloaded and installed from the official Python website. The installer will guide you through the installation process and add Python to the default installation directory. During the installation process, remember the installation path you selected for use when configuring environment variables.

Step 2: Find the Python installation path

Python is installed by default in the "Program" of the C drive Files" folder. If you chose a different location when installing Python, remember that location when configuring your environment variables. Once you find the Python installation path, you will need to add it to your system's environment variables.

Step 3: Open system properties

In the Windows operating system, we can configure environment variables by opening system properties. System properties can be quickly opened in the following ways:

Right-click "Computer" or "This PC" on the desktop and select "Properties".

In the window that opens, click "Advanced System Settings" on the left menu bar .

Under the Advanced tab of the System Properties dialog box, click the Environment Variables button.

In the environment variables dialog box that opens, you will be able to edit system and user Environment variables.

Step 4: Configure system environment variables

System environment variables are valid for all users, so we need to add the Python installation path to the system In the environment variables. In the environment variables dialog box, find the "System Variables" section and find the variable named "Path". Select the variable and click the "Edit" button.

In editing environment variables In the dialog box, click the "New" button and add the installation path of Python to the list. For example, if Python is installed in the C:\Python36 folder, then add C:\Python36 to the system variable. Make sure the path is Use semicolons to separate them.

Click the "OK" button to save the changes. Now, you have successfully added Python to the system's environment variables.

Step 5: Verify environment variable configuration

In order to verify whether the environment variable configuration is successful, we can open a new command prompt window and enter the "python" command. If everything is OK, you will See the version information of the Python interpreter. If the system cannot find the Python interpreter, it means that the environment variables are configured incorrectly.

In addition, you can also enter the "python --version" command to obtain the version information of the Python interpreter. Detailed version information.

Step 6: Configure user environment variables (optional)

If you want to configure Python environment variables for a specific user, you can Configure in the "Variables" section. In the Environment Variables dialog box, find the variable named "Path" and click the "Edit" button.

In the Edit Environment Variables dialog box, click the "New" button, And enter the installation path of Python. Make sure to use a semicolon to separate the paths.

Click the "OK" button to save the changes. The user can now use Python normally in the command prompt .

Summary

This article introduces how to configure Python's environment variables so that the Python executable file can be accessed from any location. Configuring environment variables is an important step to ensure smooth programming with Python. By adding the installation path of Python to the system and user environment variables, we can use Python commands directly in the command prompt or terminal, and can develop our own applications using Python's various functions and libraries. I wish you success in your Python programming journey!
