Python naming conventions

This document gives coding conventions example for the Python code. This style guide evolves over time as additional conventions are identified and past conventions are rendered obsolete by changes in the language itself.

1. General

• Avoid using names that are too general or too wordy. Strike a good balance between the two.
  • Bad: data_structure, my_list, info_map, dictionary_for_the_purpose_of_storing_data_representing_word_definitions
  • Good: user_profile, menu_options, word_definitions
• Never use the characters as single character variable names:
• “l“ : lowercase letter el
