Key Concepts
- -- String formatting
- The method of controlling how strings, particularly when printed, are structured and represented visually in output.
- -- format method
- A string method in Python that allows placeholders in a string to be replaced with values by either positional or named arguments.
- -- Positional argument
- An argument passed to a function or method based on its position, allowing for easier placement in strings.
- -- Named argument
- An argument that is passed to a function or method using its parameter name, allowing arguments to be supplied in any order.
- -- Formatting codes
- Special symbols within formatting strings that dictate how a given value should be displayed, like 'd' for integers and 'f' for floating-point numbers.
