Clean Terminal Setup

Clean Run Execution

Every time you run Python code, the terminal will clear first, so you always see fresh and clean output.

1. Set a default terminal

• Settings > Default Profile

2. Install ‘Code Runner’ extension

3. Edit the ‘Executor Map’ file

• Settings > Code-runner: Executor Map
• Then, Click on ‘Edit in settings.json’

4. Find the "code-runner.executorMap": {}, and the languages you will be coding in.

This setting in VS Code is used by the Code Runner extension to define custom command-line instructions for running different programming languages. The executorMap is a JSON object where keys are programming languages (e.g., “python”, “javascript”) and values are the commands used to execute code for those languages.

5. Clear the terminal before running the Python script.

By changing:

"code-runner.executorMap": {
    
    "python": "python -u",

},

To:

"code-runner.executorMap": {
    
    "python": "clear && python -u",

},

• The command clears the terminal (clear) before running the Python script.
• && ensures that python -u runs only if clear is successful.
• -u forces Python to run in unbuffered mode, meaning output is printed immediately.

6. Run Code-runner in Terminal

Scroll down and select ‘Code-runner: Run in Terminal’.
