Chapter 3: Problem 18

Write an if statement that displays the message "The number is valid" if the variable speed is within the range 0 through 200.

Short Answer

Expert verified
Question: Write an if statement that checks if a variable speed lies within the range of 0 to 200 and displays the message "The number is valid" if the condition is met.

Step by step solution

01

Define the variable speed

First, define a variable named 'speed' and assign it some value, such as: speed = _)Replace _ with some value_)
02

Set up the if statement condition

Now, we will create an if statement to check if the value of speed is within the desired range. In Python, a valid if statement should follow the syntax "if condition:". In this case, the condition is 0 <= speed <= 200. We will use the `<=` (less than or equal to) operators for comparison. Here's the if statement structure: if 0 <= speed <= 200:
03

Display the message if condition is met

Finally, we will display the message "The number is valid" if the condition in the if statement is met. To do this, we will use the `print()` function in Python. Indentation is important when writing your message under the if condition. Our final code will look like this: speed = _)Replace _ with some value_) if 0 <= speed <= 200: print("The number is valid") In this code snippet, replace _ with some value to understand better how the code works and for different values of speed in the specified range.
