Revise: Inputs, Processes, and OutputsBefore writing an algorithm, establish what information the solution needs, what work it must perform and what result it should produce. These are its inputs, processes and outputs, often shortened to IPO.
Data received by a program from outside it, for example from a keyboard or sensor.
Name the actual input data, such as age or temperature, rather than just the device that collects it.
Check that your inputs provide all the information needed for your processes, and that your outputs answer the stated problem.
In Python, convert keyboard input to a number before using it in numerical calculations.
