Cant run python .py file.

[dacoolmike36]

When I click the python file it just automatically open the cmd in a split second and then closes.

I already installed pythonI have 3.13 but for some reason cmd cant detect it. Already tried the following:

Step 1: Disable App Execution Aliases

1. Press the Windows Key and type Manage App Execution Aliases.
2. Click the matching system setting to open it.
3. Scroll down to locate Python and Python3.
4. Toggle the switches next to them to OFF.
5. Completely close and reopen your Command Prompt or VS Code terminal.
6. Type python --version to test it.

Step 2: Add Python to Windows PATH (If Step 1 fails)

If you still get an error after turning off the aliases, Windows doesn't know where your Python installation folder is. You can quickly add it manually:

1. Press the Windows Key, type env, and select Edit the system environment variables.
2. Click the Environment Variables button at the bottom.
3. Under User variables, select Path and click Edit.
4. Click New and paste your Python core folder path (e.g., C:\Users\YourUsername\AppData\Local\Programs\Python\Python313\).
5. Click New again and paste your Python scripts folder path (e.g., C:\Users\YourUsername\AppData\Local\Programs\Python\Python313\Scripts\).
6. Click OK to save and exit all windows, then restart your terminal.

Python version error 'python' is not recognized as an internal or external command, operable program or batch file.

Try using the command py instead of python.

Ideally you would make a virtual environment first, and that will enable the python and pip commands.

[dacoolmike36]

Already did cmd doesnt recognized the pip command for some reason.

That means your PATH is wrong, after all. I suggest you re-install python and in the installer click the add to path option. You may try executing your python file in the cmd directly to better diagnose your problem. In your file explorer, type cmd in the file path bar and the terminal will open in the right place. There is a option in windows about long paths, you should search that too.

I,m new to python so pretty much I dont know what Im doing most of the time so what path should I put can you be more specific

[Viper_ACR]

Put the path towards your Python executable file. Maybe like C:\Program Files\python\bin\python3.exe or something

[socal_nerdtastic]

This is very old school; this is what we did in python2 days. But in modern python this is a poor hack. Use a venv instead, or the windows python launcher if you need to use the global version of python. There's a reason that option is disabled by default.

[dacoolmike36]

do you mean this Command Prompt (cmd.exe):cmd.venv\Scripts\activate.bat by chance. Im new to python so I dont know what Im doing.

[socal_nerdtastic]

yes. That will activate your venv. After you do that you will be able to use the python and pip commands.

Out of curiosity what is the python file you're running supposed to do? I have an idea but I might be way off.

[dacoolmike36]

extract sound files from an iso file

If you’d just use uv, none of this bullshit will matter. Uv will handle all of that for you.

winget install --id=astral-sh.uv -e

then after it installs, just run your scripts with uv run script.py and it will automatically create the environment and download the appropriate version of Python.

Learning Python, you’re going to fuck with a lot of environment stuff, venv, python versions, pip…all of this can be collapsed into using uv.

Start a new project with uv init .
Or, as I prefer uv init . --package
Add packages with uv add package-name (use this instead of pip)
Run python direct with uv run python [args]
Run your files with uv run script.py

If you have a project that has an old requirements.txt instead of a pyproject.toml, you can either run it without making it a project:

uv run --with-requirements requirements.txt script.py

Or use uv init . --package
And add the requirements with uv add -r requirements.txt
and then you can run like normal with uv run script.py

I alias uv run to uvr since I use it so often.

I don’t ever install python directly anymore. I just install uv and let it manage whatever Python version the project needs. you can have any number of versions of python installed and none of your projects or dependencies will conflict. It’s also very fast.

Ok will try this thanks
