Run Python File generates incorrectly quoted script paths on macOS zsh when directory contains spaces #1995

Description

When using the "Run Python File" command in VS Code on macOS with zsh as the default shell, the generated terminal command contains incorrectly nested quotation marks if the Python script is located in a directory whose path contains spaces.

Specifically, the script path is enclosed in single quotes, but additional double quotes are included inside them. As a result, Python interprets these double quotes as literal characters in the filename, causing a file-not-found error.

Environment

• Operating System: macOS
• Shell: zsh
• Python extension: 2026.10.0
• Python Environments extension: 1.42.0
• Python interpreter: Project virtual environment (.venv)

Steps to Reproduce

1. Create a Python project in a directory containing spaces.
2. Select the project's virtual environment as the Python interpreter.
3. Create a Python script (e.g., test.py).
4. Click "Run Python File" in the upper-right corner of the editor.

Actual Behavior

VS Code generates a command with incorrectly nested quotation marks around the script path:

'/path with spaces/.venv/bin/python' '"/path with spaces/test.py"'

The additional double quotes are interpreted as literal characters in the filename, causing Python to fail to locate the script.

Expected Behavior

The command should be generated with correctly quoted paths:

'/path with spaces/.venv/bin/python' '/path with spaces/test.py'

Additional Tests

The following tests were performed:

• The selected Python interpreter works correctly.
• The reported working directory and script location are correct.
• Manually executing the correctly quoted command works successfully.
• Moving the same Python script to a directory without spaces resolves the issue.
• Disabling python.terminal.shellIntegration.enabled does not resolve the issue.
• Disabling Python environment terminal auto-activation does not resolve the issue.

The issue appears to be related to command generation or path quoting when using zsh and directory paths containing spaces.
