如何将ATOM IDE始终配置为Python IDE并实现启动即运行？

Hey there! Let's break down your two Atom + Python questions with practical, step-by-step fixes that'll make your workflow smoother.

To lock Atom into Python-focused mode permanently, follow these steps:

• Install essential Python plugins: Head to Atom's Settings (press Ctrl+, on Windows/Linux or Cmd+, on Mac), go to the "Install" tab, and search for these plugins to add:
  • script: The core plugin for running Python code directly in Atom
  • autocomplete-python: Adds smart Python code completion
  • linter-flake8: Checks your code against Python style guidelines
  • python-tools: Extra utilities like quick doc lookups and refactoring
• Set Python as the default syntax for new files: Create a new blank file, look at the bottom-right corner of Atom—it'll show "Plain Text" by default. Click that label, select "Python" from the list, then choose "Set as Default for New Files" from the popup. Now every new file you create will automatically use Python syntax.
• Set Python as the default build system: Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P), type "Build: Select Default Build System", and pick "Script - Python". Now you can run code with a single shortcut (default is Ctrl+Shift+B or Cmd+Shift+B) without having to select the language every time.

The default behavior of the script plugin requires saving files before running, but you can change that easily:

• Enable unsaved file execution: Go back to Atom Settings, find the script plugin in your installed list, click "Settings" to open its options. Look for the "Run Unsaved Files" toggle and check it. Now you can type Python code into a blank, unsaved file and hit the run shortcut to execute it right away.
• Bonus: Auto-open a Python file on Atom startup: If you want to skip even the "new file" step, add a quick script to Atom's init file. Open the Command Palette, type "Init Script" to open the file, then paste this code:

atom.workspace.open().then (editor) ->
  editor.setGrammar(atom.grammars.getGrammar('source.python'))

Save the init file, restart Atom, and it'll automatically open a new Python syntax file every time you launch the app—ready to code and run instantly.
