Best Practices

1. File Encoding

  • Must use UTF-8 encoding
  • Avoid BOM header
  • Use LF line endings (Unix style)

2. Line Length

  • Single line no more than 120 characters
  • Very long lines will be truncated on display

3. Comment Guidelines

# Single-line comments should be clear and concise

"""
Multi-line comments used for:
- Module documentation
- Function documentation
- Complex logic explanation
"""

4. Code Structure

  • Group logic with blank line separation
  • Two blank lines between functions/​classes
  • Group related imports

Display Features

Automatic Line Numbers

Code preview automatically displays line numbers for easy reference.

Syntax Highlighting

Based on highlight.js, automatically recognizes language and highlights:

  • Keywords
  • Strings
  • Comments
  • Numbers
  • Function names
  • Class names
