The above code demonstrates the functionality of the assert statement. Explain what happens when an entered number is valid and when an entered number is out of range.
What will be an ideal response?
The user is prompted to enter a number between 0 and 10. The number is read from the command line. The assert statement determines whether the user entered a number within the valid range. If the user entered a number that is out of range, then the program reports an "Invalid number" error. Otherwise, the program proceeds normally.
