how do I launch IDLE, the development environment

问题:

I am running python 2.7.1. I can't figure out how to launch the IDLE IDE. I am told it comes already installed with python, but I can't find it using spotlight.

回答1:

In the stock Mac OS X python installation, idle is found in /usr/bin, which is not (easily) accessible from Finder and not indexed by Spotlight. The quickest option is to open the Terminal utility and type 'idle' at the prompt. For a more Mac-like way of opening it, you'll have to create a small app or shortcut to launch /usr/bin/idle for you (an exercise left to the reader).

回答2:

When you open up a new terminal window, just type in

idle

Then you will see a little rocket icon show up as IDLE loads

Then the Python shell opens up for you to edit

One way to run IDLE from spotlight or an icon in the Applications folder is to build a quick Automation for it. As mentioned by other commentators, this probably isn't necessary for Python 3, as it creates a shortcut automatically, and some hand-installed versions have tools to do this automatically. But if you want to roll your own:

1. You'll need to know the terminal command to open your version of IDLE. On my Mac right now (early 2016), running python 2.7.10, it is "idle2.7"
2. Using spotlight, or in the Utilities folder, open "Automator"
3. Choose an "Application" type document.
4. Make sure "Actions" is selected in the gray bar, upper left.
5. In the actions column, find "Run Shell Script" and double-click it, or drag it to the workflow area on the right.
6. Enter the terminal command in the parameters box that appears.
7. Save your automation (I called mine "IDLE" and put it in the Applications folder, to make it easy).
8. It's now available (as soon as spotlight indexes it) via all the normal methods. The only side-effect will be that while it's running, your menu bar will have a spinning gear over in the tray area next to the clock. This indicates an automation workflow is running. Once you close IDLE, it will go away.

I think the shell command is

 python -m idlelib.idle 

but i am not a mac user so i can't test.

回答5:

1. first to launch the terminal CMD+space
2. second to input idle3
3. the idle will be activated automatically.

回答6:

1. After you launch idle from the command line (make sure idle shell window has focus), click File, click "New File". A new window opens; this is your editor.

2. Type your program in the editor. Click "File", click "Save As...". Save your file somewhere with any name you choose, and a ".py" extension to the file name.

3. Click "Run", click "Run Module" (or, F5). Assuming no errors, the results will appear in the Shell window. Edit your file & repeat as necessary.

回答7:

so for python 3.4.3 in applications a folder named "python 3.4" click that and click IDLE.

for python 2.7.9 go here https://www.python.org/downloads/ and get 2.7.9 and a folder named "python 2.7" click that and click IDLE.

回答8:

As to the earlier questions about starting IDLE: you can certainly start it from the command line. Also, if you installed Python using Homebrew, you can run 'brew linkapps' (from the command line); that will place an app for IDLE (among other things) in Launchpad (Applications folder).

回答9:

The answer of Matthewm1970 works like a charm! And if you add an & to your shell command, the automation script will end immediately. There is no spinning gear. Like so:

/usr/local/bin/idle3.5&

Note the ampersand.

Cheers.
