Of course! Here is a comprehensive guide to using Sublime Text for Python development, covering everything from setup to advanced tips.

Why Use Sublime Text for Python?

Sublime Text is a lightweight, fast, and highly customizable code editor. While it's not a full-featured IDE like PyCharm or VS Code, its speed and simplicity make it a favorite among many Python developers. It's excellent for:

• Quick scripts and edits
• Light to medium-sized projects
• Working on slower machines
• Customizing your editor to perfection

Part 1: Installation and Setup

Install Sublime Text

• Go to the official Sublime Text website.
• Download and install the version for your operating system (Windows, macOS, or Linux).
• The free version is a fully functional trial, but you'll occasionally see a nag screen asking you to buy a license.

Install the Package Control Package Manager

This is the most important step. Package Control is a package manager that makes it incredibly easy to install and manage other packages.

• Open Sublime Text.

• Open the Console:

  • Windows/Linux: View > Show Console
  • macOS: View > Show Console

• Copy the code for your version of Sublime Text from the official Package Control installation page. As of recent versions, the code is usually:

  import urllib.request, urllib.parse, urllib.error, os
  pkg_url = 'https://packagecontrol.io/install_st3.py'
  try:
      import ssl
  except ImportError:
      ssl = None
  if ssl:
      context = ssl.create_default_context()
      context.check_hostname = False
      context.verify_mode = ssl.CERT_NONE
      f = urllib.request.urlopen(pkg_url, context=context)
  else:
      f = urllib.request.urlopen(pkg_url)
  data = f.read()
  result = open(os.path.join(os.path.expanduser('~'), 'install_package_control.py'), 'wb')
  result.write(data)
  result.close()
  print('Package Control successfully installed.')

• Paste this code into the Console and press Enter.

• Restart Sublime Text.

Install Essential Python Packages

Now that Package Control is installed, you can easily add the tools you need.

• Open the Command Palette:
  • Windows/Linux: Ctrl+Shift+P
  • macOS: Cmd+Shift+P
• Type Install Package and press Enter.
• Now, type the names of the packages you want to install and press Enter for each one. Here are the essentials:

Part 2: Building Your Workflow

Running Python Code

There are a few ways to run your Python scripts.

Method 1: The Quick Way (for simple scripts)

• Save your file with a .py extension (e.g., hello.py).
• Press Ctrl+B (or Cmd+B on macOS). This will run the script in the terminal, and the output will appear in a new output panel at the bottom of the screen.

Method 2: Using SublimeREPL (for interactive sessions)

• Install SublimeREPL as described above.
• Open your Python file.
• Open the Command Palette (Ctrl+Shift+P).
• Type SublimeREPL: Python - RUN current file and press Enter.
• A new interactive Python REPL will open in a new tab, allowing you to interact with your code.

Code Completion and Linting with Anaconda

Anaconda is your best friend for Python-specific features.

• Autocompletion: As you type, a dropdown will suggest function and variable names. Press Tab to accept a suggestion.
• Code Linting: Anaconda will automatically check your code for errors and style issues (like PEP 8 violations). It will underline problematic code in red (errors) or yellow (warnings). Hover over the underline to see the message.
• Code Formatting: You can automatically format your code to conform to the PEP 8 style guide.
  • Open the Command Palette (Ctrl+Shift+P).
  • Type Anaconda: Format Code and press Enter.
• Goto Definition: Place your cursor on a function or variable name and press F12 to jump to its definition. Press Ctrl+- (or Cmd+-) to jump back.

Building a Project

• Go to File > Open Folder... and select the root folder of your Python project.
• Sublime Text will create a "workspace" for you, and you'll see your project files in the sidebar.
• You can create new files and folders directly from the enhanced sidebar (SideBarEnhancements is recommended for this).

Part 3: Customization and Advanced Tips

User Preferences

This is where you can change Sublime Text's behavior to your liking.

• Open the Command Palette (Ctrl+Shift+P).
• Type Preferences: Settings and press Enter. This opens the default settings.
• To add your own custom settings, click Preferences: Settings - User. This file will override the default settings.

Example Preferences.sublime-settings (User) file:

{
    // Set the default encoding to UTF-8
    "default_encoding": "UTF-8",
    // Show line numbers
    "line_numbers": true,
    // Highlight the current line
    "highlight_line": true,
    // Set the default indentation to 4 spaces
    "tab_size": 4,
    "translate_tabs_to_spaces": true,
    // Don't show the welcome message on startup
    "show_startup_console": false,
    // Anaconda-specific settings
    "anaconda_linter": {
        "pep8": {
            "ignore": ["E501"] // Ignore line length errors
        }
    }
}

Custom Key Bindings

You can create your own keyboard shortcuts.

• Open the Command Palette (Ctrl+Shift+P).
• Type Key Bindings - User and press Enter. This opens a JSON file where you can define your shortcuts.

Example Default.sublime-keymap (User) file:

[
    // Example: Run Python with Ctrl+Shift+B instead of Ctrl+B
    { "keys": ["ctrl+shift+b"], "command": "exec", "args": {"kill": true, "cmd": ["python", "-u", "$file"]}},
    // Example: Format code with Ctrl+Shift+F
    { "keys": ["ctrl+shift+f"], "command": "anaconda_format_code" }
]

Snippets

Snippets are small, reusable pieces of code. You can create your own.

• Navigate to Tools > Developer > New Snippet....
• A template file will be created. Edit it to create your snippet.

Example Python function snippet:

<snippet>
    <content>
def ${1:function_name}(${2:arguments}):
    """
    ${3:Docstring for the function.}
    """
    ${4:# Your code here}
    pass
    </content>
    <!-- Tab trigger to activate the snippet -->
    <tabTrigger>def</tabTrigger>
    <!-- Scope is where the snippet is active. 'source.python' means it only works in Python files. -->
    <scope>source.python</scope>
</snippet>

Save this file as function.sublime-snippet in your Packages/User folder. Now, when you type def and press Tab, the snippet will appear.

Part 4: The Sublime Text Ecosystem

• Themes: You can completely change the look and feel. Search for "Theme" in Package Control to find popular ones like Material Theme or Soda Dark.
• Color Schemes: These change the syntax highlighting. Search for "Color Scheme" in Package Control.
• Plugins: There are thousands of other plugins for everything from Git integration to Markdown editing. The Sublime Text forums and Package Control are great places to find them
