Set up Python 3 build system with Sublime Text 3

I want to configure Sublime Text 3 to build Python 3, but I don't seem to understand how the builds work. Many tutorials have told me to make a build file containing code such as:

{
    'cmd': ['/usr/bin/python3', '-u', '$file'],
    'file_regex': '^[ ]*File "(…*?)", line ([0-9]*)',
    'selector': 'source.python'
}

and save it as a file called Python.sublime-build or python3.sublime-build (much of the information I found was conflicting). One tutorial suggested creating a new folder in the ST3 Packages folder called Python and add the build file in there, whilst other tutorials suggested leaving it in the folder called User.

One tutorial explained how I had to change the Environment Variable path on my operating system to get it to work. That didn't seem to help either.

I added a folder Python to Packages (since it wasn't there already) and added in a build file with the name Python.sublime_build which featured only the code I posted above in it. Now when I attempt to run Sublime Text it gives me this error:

Error trying to parse build system:
Expected value in Packages\Python\Python.sublime-build:2:5

first you need to find your python.exe location, to find location run this python script:

import sys
print(sys.executable)

Then you can create your custom python build:

{
"cmd": ["C:\\Users\\*username*\\AppData\\Local\\Programs\\Python\\Python39\\python.exe", "-u", "$file"],
"file_regex": "^[ ]File \"(...?)\", line ([0-9]*)",
"selector": "source.python"}

You can change the location, In my case it is C:\Users*username*\AppData\Local\Programs\Python\Python39\python.exe

Then save your new build. Don't change the file extension while saving.

Here is a very simple Python Sublime Text build system that works when python scripts are invoked with py file_name.py.

Just create py.sublime-build by Tools > Build System > New Build System and add the contents below:

{
    "cmd": ["python3", "$file"]
}

You can select it in Sublime Text editor by going to Tools > Build System > py and building with Ctrl + b.

Note: If your filesystem doesn't python3 than you need to provide path/to/python3 and it should work.

I'd like to add just one point to the accepted answer:

when you edit the cmd portion of the snippet below, make sure to add the file address (with forward slash) where python is kept on your computer.

{
"cmd": ["c:/Python32/python.exe", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}

How to know where python is installed on your system? Two ways for windows users:

  1. Open Command prompt and do the following query: where python If it shows the path to python.exe, copy and paste it with /. If it shows some error, then follow process below:
  2. Go to start -> Search for python shortcut (not IDLE) -> Right Click -> More -> Open file location -> Right click the shortcut -> Properties -> Target -> Path is now visible -> Copy and paste it in the field above.

And to add on to the already solved problem, I had installed Portable Scientific Python on my flash drive E: which on another computer changed to D:, I would get the error "The system cannot find the file specified". So I used parent directory to define the path, like this:

From this:

{
    "cmd": ["E:/WPy64-3720/python-3.7.2.amd64/python.exe", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

To this:

{
    "cmd": ["../../../../WPy64-3720/python-3.7.2.amd64/python.exe","$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

You can modify depending on where your python is installed your python.

Version for Linux. Create a file ~/.config/sublime-text-3/Packages/User/Python3.sublime-build with the following.

{
 "cmd": ["/usr/bin/python3", "-u", "$file"],
 "file_regex": "^[ ]File \"(...?)\", line ([0-9]*)",
 "selector": "source.python"
}

Run Python Files in Sublime Text3

For Sublime Text 3, First Install Package Control:

  • Press Ctrl + Shift + P, a search bar will open

  • Type Install package and then press enter Click here to see Install Package Search Pic

  • After the package got installed. It may prompt to restart SublimeText

  • After completing the above step
  • Just again repeat the 1st and 2nd step, it will open the repositories this time
  • Search for Python 3 and Hit enter.
  • There you go.
  • Just press Ctrl + B in your python file and you'll get the output. Click here to see Python 3 repo pic

It perfectly worked for me. Hopefully, it helped you too. For any left requirements, visit https://packagecontrol.io/installation#st3 here.

Steps to Make Sublime Text a Python IDE (Windows)

Tested successfully on Sublime Text 3. Assuming Sublime Text and package control are already installed . . .

  1. Install Python (python.org) and pay attention to where it is installed or choose a simple location like the C drive, agreeing to remove character limit at the end of the installation.

  2. Install package SublimeREPL (Cntrl + Shift + P, Package Control - Install Package, SublimeREPL, Enter).

  3. Go to Preferences, Package Settings, SublimeREPL, Settings - User.

  4. Paste in the following, updating the file path to your python installation folder, as needed. You may customize these and choose whatever syntax you like (last line) but I prefer my output in plain text.

    {
  "default_extend_env": {"PATH":"C:\\Program Files\\Python36\\"},
  "repl_view_settings": {
  "translate_tabs_to_spaces": false,
  "auto_indent": false,
  "smart_indent": false,
  "spell_check": false,
  "indent_subsequent_lines": false,
  "detect_indentation": false,
  "auto_complete": true,
  "line_numbers": false,
  "gutter": false,
  "syntax": "Packages/Text/Plain text.tmLanguage"
  }
}

  5. Save and close the file (SublimeREPL.sublime-settings).

  6. Go to Tools, Build System, New Build System.

  7. Replace all existing text with the following:

    {
"target": "run_existing_window_command", 
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"
}

  8. Cntrl + S or save as "C:\Users[username]\AppData\Roaming\Sublime Text 3\Packages\User\SublimeREPL-python.sublime-build" updating username or path as needed. This should be wherever your settings and builds are stored by Sublime Text.

  9. Go to Tools, Build System, select SublimeREPL-python.

  10. All done--now to test. Open or create a simple python file, having a *.py extension and save it wherever desired.

  11. Make sure the file is open and selected in Sublime Text. Now, when you press Cntrl + B to build and run it, it will open another tab, titled "REPL [python]", executing and displaying the results of your python code.

If you would like to go a step further, I highly recommend making the follow changes, to allow Sublime to reload your executed python in the same window, when you press Cntrl+B (Build), instead of it opening a new tab each time:

Add the following line in the "repl_python_run" command in (Preferences, Browse Packages) SublimeREPL\config\Python\Main.sublime-menu, right before the "external_id": "python" argument:

"view_id": "*REPL* [python]",

and then to change the line:

if view.id() == view_id

into:

if view.name() == view_id

in SublimeREPL\sublimerepl.py.

If you are using PyQt, then for normal work, you should add "shell":"true" value, this looks like:

{
  "cmd": ["c:/Python32/python.exe", "-u", "$file"],
  "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
  "selector": "source.python",
  "shell":"true"
}

The reason you're getting the error is that you have a Unix-style path to the python executable, when you're running Windows. Change /usr/bin/python3 to C:/Python32/python.exe (make sure you use the forward slashes / and not Windows-style back slashes \). Once you make this change, you should be all set.

Also, you need to change the single quotes ' to double quotes " like so:

{
    "cmd": ["c:/Python32/python.exe", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

The .sublime-build file needs to be valid JSON, which requires strings be wrapped in double quotes, not single.
