如何让 Python 脚本在 Windows 10 上打开并执行？

Question

The Situation:

I am trying to install and set-up Python 3.9.7 on Windows 10 Pro. However after install I am unable to open any Python Scripts from the Command Prompt, Visual Studio Code, or PyCharm.

What I have done so far: *

1. Downloaded Python, adding to Path during installation and also removed the Path maximum lenght limit. Python is installed in:

C:\Users\enriq\AppData\Local\Programs\Python\Python39\

2. Python is recognized and executed from command promp as follows:

C:\Users\enriq>python 

Python 3.9.7 (tags/vPython 3.9.7 (tags/v3.9.7:1016ef3, Aug 30 2021, 20:19:38) [MSC v.1929 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information

3. Tried to open an IDLE executable in the command prompt:

C:\Users\enriq>Desktop>MyScripts>intro.py

'Desktop' is not recognized as an internal or external command, operable program or batch file.

4. In Environment Variables:

• Added at the end of System Path the User Path.
• Added at the beginning of User Path, the System Path. Both paths are identical now;

%SystemRoot%\system32 %SystemRoot% %SystemRoot%\System32\Wbem %SYSTEMROOT%\System32\WindowsPowerShell\v1.0
%SYSTEMROOT%\System32\OpenSSH
%USERPROFILE%\AppData\Local\Microsoft\WindowsApps C:\Users\enriq\AppData\Local\Programs\Python\Python39\Scripts
C:\Users\enriq\AppData\Local\Programs\Python\Python39
C:\Users\enriq\OneDrive\Desktop\MyScripts

5. In Registry Editor:

Computer\HKEY_CURRENT_USER\Environment, set the type of the User Variable to REG_EXPAND_SZ.

6. Clicked OK after every change, checked there are no spaces after every line in the environment variables. I tried to run the script after every change.

Additional Information:

My machine is:

HP laptop recently formatted: processor Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz 2.90 GHz, system type: 64-bit operating system, x64-based processor.

The Question:

How could I resolve this and get Python to open the scripts?

Answer 1

This is really a question than an answer but have you associated.py with Python? You can do it this way.

Answer 2

When you say you're trying to open a python script, do you mean you want to run the script, or you want to edit it? In either case, step 3 is where things are going wrong. To run your script, change your command to something like:

python C:\Users\enriq\Desktop\MyScripts\intro.py

If you want to inspect or edit the source code, you should be able to do that via IDLE's graphical user interface. If you already have IDLE open, look for File > Open in the menu bar and browse to the location of the file you want to edit.

Outside of using IDLE's user interface to open the file, you could also browse to the intro.py file icon in the MyScripts folder on your desktop and click to open it. Windows will open the file using whatever application is mapped to .py files, and if there is no existing mapping, it should ask you which application you want to use to open the file. You can then choose IDLE, or whichever other editor you like.

Answer 3

To execute. py files you have to invoke python.exe like this: python file.py or you can execute code with the - c switch: python -c "print('hi')" To execute installed modules use the -m switch: python -m pip I remember that, in the Python installer for Windows, there's also the option to associate. py extension with Python (but personally I don't see the need, since most of the time I use an IDE). Official docs in case you haven't read them: https://docs.python.org/3/using/windows.html

Answer 4

Try this code on you terminal C:\Users\enriq>Desktop>MyScripts>python intro.py or this C:\Users\enriq>Desktop>MyScripts>py intro.py
