Python Environment Installation

Download the Python installation package

Enter thePython’s official websiteUnder my Downloads TAB, clickWindowThe download list page is displayed

Here we see two broad categories:

• Stable Releases: Tested and iterated with fewer bugs. Can be used for work and study
• Pre-releases: Is being tested and is prone to anomalies. But it contains new language features/functions/syntax, suitable for learning/researching new language features

We’re mostly learning here, so we’re going to go with Stable Releases

Stable versions fall into two categories:

• Python 2.x: Python 2 was released in 2000 and the stable version is Python 2.7. But in March 2018, the language’s authors announced on the mailing list that Python 2.7 would end support on January 1, 2020. They even made a website to count down the days
• Python 3.x: Python 3 was released on December 3, 2008 and is not fully compatible with Python 2. The latest stable release is Python 3.7.7, which was released in March 2020

This course will use Python 3.7.7, but there are many options below Python 3.7.7

The executable installer is the same as the Python 3.7.7-Windows x86-64 executable installer.

Install Python3

Create the Py3 environment directory folder: D:\Dev\env\python3.7, open the download directory and double-click python-3.7.7-amd64.exe to go to the installation configuration interface

• Click Add Python 3.7 to PATH. Python3.7 path to the system configuration path for easy execution in any directory.
• chooseCustomize installation. The system can be installed by default, but it is not conducive to future management. So choose custom installation

Do you need to install Python documentation, PIP extension package manager, IDLE command line tools… It’s the day-to-day development that we need to chooseThe Next step

The image below presets here,

• Select Install for all Users and set Python3.7 to the global environment.
• Configure the Customize Install Location custom path, which is configured as the Py3 environment directory folder above: D:\Dev\env\python3.7

thenThe Next stepThe program is installed according to your configuration. We will wait for a moment.

The installation succeeded message is displayed.

To verify the installation, run the CMD command on the clipython, the following image appears

Don’t panic if you get an error — Python is the language of the moment, and everyone else has. Online search can be solved, about “search skills can click to urge some degree from good”, here I will not be too tired to describe.

Here are some common tools:With questions in mind, reading more documents and summarizing more helps deepen the understanding of the language

Python3.7 support is already in place. Next we need to install PyCharm, our common Python development tool

PyCharm development tool installation

Download PyCharm

Click to enterPyCharm website, click on theDOWNLOAD

PyCharm comes in three systems and two versions. I don’t need to say more about the system. The key is the version:

• Community is the Community edition, free and open source. We’ve had enough development work.
• Professional is Free trial(30 days Free trial)… Such as support.

Here we downloadCommunityCommunity edition, clickDowload. Wait for the download to complete.

Install PyCharm

Once the download is complete, go to the download directory and find PyCharm and double-click to run it

Click on theNext>And in theDestination FolderSelect the installation directory: D: Dev\ Tool \PyCharm2020 (custom). Click next

Select your own configuration based on the following figure, then Next and then Install. We’ll wait a moment…

Once installed, go back to the desktop and find the PyCharm icon and double-click to run

Run PyCharm

Here’s the JetBrains Privacy policy, and we checked itI have read and agreed with the termsAnd then Continue

The following figure asks whether to share personal usage data, abnormal situation. I’m going to say “Don’t Send.”

Select the PyCharm UI theme

Do you want to install some additional plug-ins, which you need to install here? Start using PyCharm

PyCharm is now installed

Create project iMOOC and project virtual environment

Double-click on the desktop to run PyCharm and clickCreate a New Project

Configure Location (project path) to D: Dev workplace imooc (custom). One thing to note here is Project Interpreter (the Python runtime environment for your Project). If you are familiar with this, you can directly select New Environment Using. PyCharm will help you generate a virtual execution environment for your Project.

But since the course itself is going to teach you how to configure it manually, rightProject virtual execution environmentSo let’s choose firstExisting interpreterSelect the global Python execution environment and clickCreateCreate a project
