This applies to ST3  Win   not sure about ST2    To have the output visible in Sublime as another file    one for errors   do this    Create a new build system  Tools  gt  Build Systems  gt  New Build System    Use the following configuration                     cmd     python exe     file    1      file name   STDOUT   txt    2      file name   STDERR   txt             selector    source python            shell   true           working dir     file dir           For your Python file select the above build system configuration file  Tools  gt  Build Systems  gt   your new build system filename  ctrl   b Now  next to your file  e g   file py  you ll have  file   STDOUT   py  and   file   STDERR   py   for errors  if any  If you split your window into 3 columns  or a grid  you ll see the result immediately  without a need to switch panels   windows

One thing to note about the aforementioned build system  you can write  and use  custom  sublime-build files or even per project build systems clause  in your project settings   This allows you to do useful things like a fancy test runner with ANSI colors output   For even more  full IDE  features  you can use the excellent SublimePythonIDE package    code completion  intel  jump to definition  amp  object description proper linting pep8 supports different interpreters with virtualenv   Disclosure  I ve contributed a PR to that package  and I use it all the time  but there are others

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  quot  PATH   lt python folder gt  quot  for example  SETX  M PATH  quot  PATH  C  Python27 C  Python27 Scripts quot   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

Use a real python console alongside Sublime  Both Sublime s build system and SublimeREPL  the answers above  are limited in that you can t easily interact with the workspace variables after you run your file    If you want to run a script  then work in a REPL-like fashion  like you would in an IDE   then I recommend having Sublime open alongside an IPython console  Using AutoHotKey  Windows  or AutoKey  Linux   you can set this up such that a single shortcut will copy the filename  or just the selected code  and then paste this in the console to run the file   Detailed instructions for Linux or Windows
