Question: Write an if statement to check if the variable "speed" is outside the range of 0 to 200 and display the message "The number is not valid" if it is. Answer: ```python if speed < 0 or speed > 200: print("The number is not valid") ```

Step by step solution

Understanding the condition

First, analyze the condition: "The number is not valid" should be displayed if the value referenced by speed is outside the range of 0 to 200. This means that if speed is less than 0 or greater than 200, the message should be displayed.

Writing the if statement

Write the if statement to check if the value of speed is less than 0 or greater than 200. If the condition is met, it will print the message "The number is not valid". ```python if speed < 0 or speed > 200: print("The number is not valid") ``` This will ensure that the message is only displayed when the value of speed is outside the specified range of 0 to 200.
