The Pythonb interpreter is the bridge that allows code written in Python to be executed by CPU and is the core software of the Python language. Users candownload the appropriate version(Python 3.7 is used here) of the interpreter form www.python.org/. After the installation is completed, you can call the python.exe program to execute the source code file written in Python(.py files).
Here we choose to install Anaconda software that integrates a series of auxiliary functions such as the Python interpreter, package management, and virtual environment. We can download Andacoda from www.anaconda.com/distribution/#download-section and select the latest version of Python to download and install. As shown in Figure 1-22, check the "Add Anaconda to my PATH environment variable" option, so that you can call the Anacondat program through the command line. As shown in Figure 1-23, the installer asks whether to install the VS code software together. Select Skip. The entire installation process lasts about 5 minutes, and the specific time depends on the computer performance.
After the installation is complete, how can we verify that Anaconda was successfully installed? Pressing the Windows+R key combination on the keyboard, you can bring up the running program dialog box, enter "cmd," and press Enter to open the command-line program "cmd.exe" that comes with Windows. Or click the Start menu and enter "cmd" to find the "cmd.exe" program and open it. Enter the "conda list" command to view the installed libraries in the Python environment. If it is a newly installed Python environment, the listed libraries are all libraries that come with Anaconda, as shown in Figure 1-24. If the "conda list" can pop up a series of library list information normally, the Anaconda software installation is successful. Otherwise, the installation failed, and you need to reinstall.
