- route decoratorA route decorator is a Flask decorator that associates a URL path and request methods with a Python view function.
- JSONJSON is a text-based data-interchange format that represents structured data using objects, arrays, and primitive values.
- top-down designTop-down design is a development technique that defines a program's overall structure before detailing its component parts.
- orderAn order is a customer's requested set of products and options from a shop.
- jsonThe Python json module provides functions for encoding Python data structures as JSON and decoding JSON into Python values.
- json.dump()The Python json.dump function serializes a Python object as JSON and writes the result to a file-like object.
- json.loadThe Python json.load function reads JSON from a file-like object and deserializes it into a Python value.
- return statementA return statement exits a function and optionally supplies a result to its caller.
- order listAn order list is a collection of customer orders presented for review or processing.
- PythonPython 3 is the third major version of the Python programming language.
- continue statementA continue statement skips the remaining statements in the current loop iteration and starts the next iteration.
- placeholderA placeholder is a temporary implementation that stands in for intended functionality until the real implementation is written.
- trimThe Python string strip method returns a string with specified leading and trailing whitespace or characters removed.
- methodA method is a function associated with an object and invoked through that object.
- readlinesThe Python file readlines method returns the lines read from a file as a list of strings.
- local variableA local variable is a variable whose visibility is restricted to the function or block where it is defined.
- read-execute-print loopA REPL is an interactive programming environment that repeatedly reads input, evaluates it, displays results, and waits for more input.
- function declarationA function definition is a Python statement that declares a function's name, arguments, and indented body.
