Background:

Python language: it is a scripting language that combines interpretation, compilation, interaction and object-oriented. In recent years, with the development of artificial intelligence and big data, it is used more and more frequently, so learning python is very useful for future work and study.

Applicable crowd:

People who have some knowledge of programming, for example, have had a little contact with programming languages such as C & M, C & Q, Java, etc.

Download and install Python:

The download of python is mainly recommended to the official website, https://www.python.org/. The page you see when you open the connection is as follows:

Then click download to find the version that suits your computer. Currently, there are two main versions of python, one is python3.7 and the other is python2.7.15, as shown in the following figure:

About why there are two versions of python:

Mainly because the python3X version is an upgrade to the python2X version (so there is a situation: for some functions of python2X, python3X does not support, for some functions of python3X, python2X does not support), the python3X version is more suitable for future development applications, but because some of the original applications are based on the python2X version, the company also updates the python2X version, if you want to learn python, it is recommended to learn the python3X version However, in order to better transplant other people's code when programming in the future, it is recommended that both versions of python be installed.

About the choice of python installation package: for the version of python3X, directly select the corresponding version of the computer:

For the python2X version, you may have some difficulties in choosing, so you need to explain here that if your computer is the first 64-bit choice, and if your computer is the second 32-bit choice, as shown below:

After the version is selected, just run the corresponding installation package and install it foolishly. However, instead of using python, you can configure the Path environment variable as follows:

Right-click my computer-> Properties-> Advanced system Settings-> Environment variables, and you will see the following window:

Follow the window prompt to add your python installation path (for example: my python installation path is: d:\ Program Files (x86)\ python), and click OK.

After the installation is successful, open your command prompt tool (that is, the small black window): enter the command: python, if you see the following: you have successfully installed.
