Description

Behaviour

The top-right Run Python File button fails when the Python script is in a path containing spaces and Python Environments handles terminal execution.

Expected: Python runs the selected file.

Actual: The terminal receives a script argument with literal double quotation marks inside single quotes. Redacted equivalent of the observed command:

/usr/local/bin/python3 '"/path with spaces/main.py"'

Python reports [Errno 2] No such file or directory because the double quotation marks become part of the filename. The error path includes the current directory followed by "/path with spaces/main.py" instead of the actual script path.

Steps to reproduce

1. Install and enable the Python and Python Environments extensions.
2. Open a Python file inside a directory with spaces in its path.
3. Click the top-right Run Python File button.
4. Observe the terminal command and error.

Running the same script directly with a correctly quoted shell path succeeds.
