Snake Case, Database Schemas & Python Style Guide

In Python's official PEP 8 style guide, function names and variable names must be written in lowercase with words separated by underscores (e.g. calculate_total_price). Relational database management systems (RDBMS) such as PostgreSQL, MySQL, and SQLite default to case-insensitive or lowercase identifier folding; using snake_case for table and column names avoids quoting issues and eliminates SQL syntax collisions.

Standard string splitters often mangle consecutive capital letters in compound variables (e.g. turning getHTTPResponse into g_e_t_h_t_t_p...). Our converter uses lookahead and lookbehind regular expression tokenization to separate uppercase acronym blocks cleanly into words (e.g., parseJSONPayload → parse_json_payload, userIDV2 → user_id_v2).

Standard snake_case: Public variable or function name.
Single Leading Underscore _snake_case: Weak "internal use" or private convention in Python.
Double Leading Underscore __snake_case: Invokes class name mangling to prevent subclass collision.
Dunder __snake_case__: Reserved special methods (e.g., __init__, __str__).
SCREAMING_SNAKE_CASE: Constants and environment variables in Python, C/C++, Java, and Bash.

All tokenization, regex splitting, diacritic normalization, and formatting occur 100% locally inside your web browser via native client-side JavaScript. No strings, confidential database schemas, code snippets, or API keys are ever transmitted over the network or logged to external servers.
