Whoever's writing Python Before coding, you need to let your computer have a Python Interpreter , How to install this interpreter ？ Now I'll explain it in three steps . The first step is to Python Download one from the official website Python, The second step must be to install , The third step is to check whether you have installed . There are also some matters needing attention in the process of downloading and installing , When I write the steps, I will insert them , When you download and install, just follow my steps step by step . Okay , I'm not talking anymore , Let's start ~
official ：https://www.python.org
official windows Download address ：https://www.python.org/downloads/windows
official macos Download address ：https://www.python.org/downloads/macos
Open up the official windows Download the page of the address , We can see all the present Python edition , I'll take it here 3.7.3 Let's demonstrate this version , The computer I demonstrated is 64 Bit , I think most computers now 64 Place bar .
## 1、 First , Scroll down to find this version （2019 Year of 3.7.3 edition ）, Then click the download I marked in the figure below .
Expand your knowledge 1： Why is 3.7.3 This version ？
because 3.7 perhaps 3.8 It's relatively old and stable , No matter you are windows7 still windows10 Can be installed , The requirement to download the latest version is windows8 That's all , But my computer is not （ To be honest, I don't want to upgrade ）.
Expand your knowledge 2： Why Windows x86-64 executable installer？
Because our computer system is windows, The suffix of the downloaded and installed program file is exe, So it must be the right choice .
## 2、 This is the installer I downloaded in the background , Just like this , The suffix is really exe.
Double click the downloaded program file in the figure above , An interface will appear , We click ’ function ’ Just fine , When I hit run , Will enter a new installation interface , Then you check the bottom box and click Install Now . The general installation path is the default path , If you want to modify the path name, you'd better write it in English , Then just wait for the installation .
Knowledge expansion ：Add Python 3.7 to PATH Why do you have to tick ？
Because add Python 3.7 Into the environment variable .
Follow the installation steps in the previous step , We can see the path of our installation , My path is the default , Then, according to the path, you can find some program files for the final installation , That means you have successfully installed .
Be careful ： Maybe some students can't find this path , Well, it's probably this AppData The file is hidden .
Unhide steps ： If you are windows7 System , Follow this step .
step ： Open... On your desktop ‘ Computer ’ ---》 Click on the top left ‘ organization ’---》 Open... In the pop-up menu ‘ Folders and search options ’---》 Get into “ Folder options ” after , Switch to “ see ” tab ---》 There's a... Down there ‘ Advanced settings ’ Under frame ---》 find “ Show hidden files 、 Folder or drive ”, Then check it out. , Finally, click OK .
Okay , Probably just these steps , This is windows Installation on system Python, If you want to know more about Python Environmental installation PyCharm Use the tutorial , You can go to this address to see the article tutorial . Thank you for watching , If it helps you , You can like the collection and pay attention to me , Later I will continue to write more Python Articles on .
