Python development_python installation

Python can run on a variety of platforms, including our common ones: Windows, Unix, Linux, and Macintosh.

This article will introduce in detail the process of installing Python in Windows operating system. My operating system is Windows 7, 32-bit version.

When installing Python, we can choose to install it from the source code or select the already compiled binary version for installation. I chose the latter here.

Step 1 Download the installation package

We download the Python installation package from the official Python website: https://www.php.cn/link/50959eee56aa5f4695971b375b69354f .

The version I chose is: python-3.3.2.msi

After clicking to download, we will get a python-3.3.2.msi installation package with a size of 19.3 MB.

Step 2 Installation

After downloading the python-3.3.2.msi installation package, double-click the file to start the installation.

The installation directory I chose is: E:\Python33

Click Next to start the installation process, which usually takes several minutes.

After the installation is completed, click Finish to end the installation.

Step 3 path settings

Usually, you can use it directly after installing Python. You can check whether you can enter Python's interactive mode by typing Python in the command line.

If you cannot enter, it may be because of the environment variable setting problem and some adjustments are needed.

In Windows, you can add Python's directory to the environment variable path through a command prompt, for example: %path%; C: Python, and press Enter.

Alternatively, you can set environment variables through the graphical interface, the path is: Computer -> Properties -> Advanced System Settings -> Advanced -> Environment Variables.

Step 4 Effect

After the installation is completed, the files in the installation directory are as follows:

At this point, the Python installation process is completed.
