## Definition

a short way of writing the word 'string'. You see this most often in computer programming or when looking at lists of data.

For teachers: a standard abbreviation for 'string', primarily used in technical contexts to denote a sequence of characters. Often serves as a data type identifier or a variable prefix in source code.

## Examples

- The function requires a str input.
- The programmer defined the variable as a str to ensure the user's name was stored as text rather than a number.
- When parsing the raw data file, the script converts each entry into a str before performing the regex match to identify specific patterns within the logs.

## Usage notes

- Commonly used in programming languages like Python as a built-in class or type name.
