What is snake_case?

snake_case is a naming convention that uses underscores to separate words, with all letters in lowercase. It is widely used in Python (as recommended by PEP 8), Ruby, and database systems. The format improves readability for multi-word identifiers and is the standard for naming columns, tables, and Python variables.
