Q: What is the difference between PascalCase and camelCase?

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word including the first word. Example: MyVariableName. camelCase keeps the first letter lowercase. PascalCase is commonly used for class names in programming.

Q: What is snake_case used for?

snake_case uses underscores between words with all letters in lowercase. Example: my_variable_name. It is the standard naming convention in Python for variables and functions, and is also used in database column names and file names.
