How do I run Python code from Sublime Text 2?

I want to set up a complete Python IDE in Sublime Text 2.

I want to know how to run the Python code from within the editor. Is it done using build system? How do I do it ?

Solution 1:

Tools -> Build System -> (choose) Python then:

To Run:

      Tools -> Build

      -or-

      Ctrl + B

      CMD + B  (OSX)

This would start your file in the console which should be at the bottom of the editor.

To Stop:

       Ctrl + Break or Tools -> Cancel Build

       Fn + C (OSX)

You can find out where your Break key is here: http://en.wikipedia.org/wiki/Break_key.

Note: CTRL + C will NOT work.

What to do when Ctrl + Break does not work:

Go to:

Preferences -> Key Bindings - User

and paste the line below:

{"keys": ["ctrl+shift+c"], "command": "exec", "args": {"kill": true} }

Now, you can use ctrl+shift+c instead of CTRL+BREAK

Solution 2:

Edit %APPDATA%\Sublime Text 2\Python\Python.sublime-build

Change content to:

{
    "cmd": ["C:\\python27\\python.exe", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

change the "c:\python27" part to any version of python you have in your system.

Solution 3:

On Mac OS X, save your file with a .py extension. Press ⌘ + B. It runs in a window below.

Solution 4:

To RUN press CtrlB (answer by matiit)

But when CtrlB does not work, Sublime Text probably can't find the Python Interpreter. When trying to run your program, see the log and find the reference to Python in path.

[cmd:  [u'python', u'-u', u'C:\\scripts\\test.py']]
[path: ...;C:\Python27 32bit;...]

The point is that it tries to run python via command line, the cmd looks like:

python -u C:\scripts\test.py

If you can't run python from cmd, Sublime Text can't too.
(Try it yourself in cmd, type python in it and run it, python commandline should appear)

SOLUTION

You can either change the Sublime Text build formula or the System %PATH%.

To set your %PATH%:
*You will need to restart your editor to load new %PATH%
- Run Command Line* and enter this command: *needs to be run as administrator
  SETX /M PATH "%PATH%;<python_folder>"
  for example: SETX /M PATH "%PATH%;C:\Python27;C:\Python27\Scripts"
- OR manually: (preferable)
  Add ;C:\Python27;C:\Python27\Scripts at the end of the string.
To set the interpreter's path without messing with System %PATH% see this answer by ppy.
