Short Answer

Expert verified

Question: Write an if statement that checks whether a variable "hours" is within the range 0 to 80. If "hours" is outside this range, the program should print "The number is not valid." Answer: ```python if hours < 0 or hours > 80: print("The number is not valid") ```

Step by step solution

Define the variable hours

First, you'll need to define the variable "hours." In a real-world scenario, this variable would likely get its value from user input or another part of the program. For the sake of this example, we'll simply assign an arbitrary value to the variable. ```python hours = 10 # Example value, can be replaced by any real value or user input. ```

Create a conditional (if) statement

Next, you'll need to create an if statement to check whether the variable "hours" is outside the range 0 to 80. Remember, the if statement should check for both "hours" less than 0 and "hours" more than 80. ```python if hours < 0 or hours > 80: ```

Add the print statement

If the condition specified in the if statement is True, you'll want to print the message "The number is not valid." To do this, add the print statement inside the if statement block (indented under the if condition). ```python if hours < 0 or hours > 80: print("The number is not valid") ```

Test the code

Finally, test your code by running the program. To do this, combine the previous steps and run the program with different values of "hours" to make sure the if statement is working correctly. ```python hours = 10 # Example value, can be replaced by any real value or user input. if hours < 0 or hours > 80: print("The number is not valid") ``` If everything is working correctly, the program should print "The number is not valid" when the variable "hours" is outside the range 0 to 80 and do nothing if "hours" is within the range.
