Hello everyone, Xiaobian will answer the following questions for you, python official website download step diagram, python official Chinese document download, let us take a look now!
Python official website URL python official website python official website URL in Chinese. For example, if we want to grasp a good programming language, how do we start learning ? Many friends who have just started learning python will encounter various difficulties when downloading python, such as not being able to enter the official website, and not being able to install after downloading , environment variables report errors, etc.
Python features: simple syntax, quick to get started Considering that some cmd consoles have not been used much, so I wrote some details
Then let's start downloading python installation:
1. Download the python installation package from the official website Official website:
Click [Downloads] on the NAV in the navigation bar to enter the download page. Since it is a foreign server, it is a bit slow to open the webpage. After all, the data is floating in the sea.
2. Enter the page as follows:
findDownloads
If you want to learn python3 in one or two days if you want to learn python2, the syntax is similar.
3. After the download is complete, find the python msi installation package file [right-click properties]:
Click the contact lock and then click OK to avoid the file being locked after win10 or authorized users install
4. Then click Run under the Start menu
Or use the shortcut key win + R to open (win) the key between ctr and alt
5. Run the cmd console
6. Then change the path to the path to download python. For example, mine is under D:/download
First enter D: to change the drive letter
7. Then use the cd command to go to the directory of the installation package
8. (1). Enter dir to view what files are in the current folder
(2). Enter msiexec /i python-2.7.13.msi to execute with administrator privileges to avoid errors in win10 system user installation,
(3). Then the installation file will be run with administrative privileges:
9. The first one is to install to all users (default next step Next)
The second is to install to the currently logged in user
10. Then enter the installation folder. The python file under C is not large by default. There is no need to consider the problem of system performance occupied by C. If you have obsessive-compulsive disorder users, you can change it and click Next.
11. Add python environment variables and select Will be installed on local hard drive
If there is no environment variable added in this step, you need to manually configure it to avoid cumbersome operations and try to check it.
Then Next next step
Then the file will be released to the directory you just set
12. Finally, this pops up to indicate that the installation is complete and click Finish to complete, so that python is installed
Finally go back to the cmd console
13. Enter a python and press Enter to enter the shell interactive mode of python
We enter python's basic printing syntax
print "I will install python!"
Remember to put a space after print, and then wrap it in [English quotation marks]
14. Isn’t Python very simple? Let’s click the start menu to find:
IDLE that comes with Python
This is also the shell program
15. Then click New File under the file menu to create a new file
