10.8 LAB: Step counter - exceptions

 

A pedometer treats walking 2,000 steps as walking 1 mile. Write a steps_to_miles() function that takes the number of steps as a parameter and returns the miles walked. The steps_to_miles() function throws a ValueError object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() program that reads the number of steps from a user, calls the steps_to_miles() function, and outputs the returned value from the steps_to_miles() function. Use a try-except block to catch any ValueError object thrown by the steps_to_miles() function and output the exception message.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print(f'{your_value:.2f}')

 

The code I have so far(Python Code):

import sys
def steps_to_miles(steps):
    try:
        if steps<0:
            raise ValueError('Exception: Negative step count entered.') 
        return steps/2000
    except:
        print("Exception: Negative step count entered.")
        sys.exity(0)
if __name__ == "__main__":
    steps=int(input())
    miles=steps_to_miles(steps)
    print(f"{miles:.2f}")
    

got these errors:

Traceback (most recent call last): File "main.py", line 5, in steps_to_miles raise ValueError('Exception: Negative step count entered.') ValueError: Exception: Negative step count entered. During handling of the above exception, another exception occurred: Traceback (most recent call last): File "main.py", line 12, in <module> miles=steps_to_miles(steps) File "main.py", line 9, in steps_to_miles sys.exity(0) AttributeError: module 'sys' has no attribute 'exity

Test stepsToMiles(-3850), should throw an exception
ValueError: Exception: Negative step count entered. During handling of the above exception, another exception occurred: AttributeError: module 'sys' has no attribute 'exity'
Your output
Exception: Negative step count entered.
