Read a number out of a message
Definition and example
Read a number out of a message is the focus of this lesson. Students write "Rs 11667" inside a sentence. Pulling the number out of text is the first step of turning a chat message into structured data. The task asks you to apply that idea in a small example: Why pull numbers out of messages. Before you run the code, predict what should happen. Then Inspect the printed output and the values your program uses and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
