Output
Computer Science: KS3, topic 2.3.3
Output
Output is necessary so that we can see the results of programs.
Why do we need outputs?
- Outputs are important so that we can communicate the result of a program to the user.
- Outputs are usually delivered as text onto the screen.
The print function
- The output function in Python is called ‘print’.
- The output function ‘prints’ data onto the screen.
- E.g. print(“Hello, world!”) would output the text “Hello, World!”.
What data can be outputted?
- Output data must be a string before we can print it.
- If we want to display data that is not a string, then we must first cast it to a string.
