Study Notes
Programs and Input/Output
- A program is a set of statements performing a specific task when run by a computer. It's also called software.
- A "code segment" is part of a program.
- Program behavior describes how a program runs and how a user interacts with it.
- Input is data sent to a computer for processing by a program. It can be tactile, audio, visual, text, etc., and comes from a user or other programs.
- Input is assigned to variables. For example,
first_name = input("What is your first name?")gets input from the user and assigns it to the variablefirst_name. - An "event" is associated with an action and supplies input data to a program. (e.g., key press, mouse click)
- Event-driven programming executes statements when triggered, rather than sequentially.
- Output is what the computer generates from input. Print statements are an example of output.
- Print statements can combine variables and text to create output. For example,
print("My favorite color is " + color), wherecoloris a user input variable. - Concatenation combines variables and text in print statements with "+".
- Programs often need a single print statement for autograder checking.
- Autograders check for exact matches of capitalization, punctuation, and spacing in print statements.
- The provided example input/output does not guarantee code works with all possible varied inputs. Ensure the code works with varied input to be certain it passes the autograder.
