Debugging

Explain the overall purpose of this program, summarizing what you’ve covered.

# Initial version with an error
x = 10
y = 0
try:
    result = x / y
except ZeroDivisionError as e:
    print("Error:", e)

# Debugging steps to fix the error
try:
    if y == 0:
        raise ValueError("y cannot be zero")
    result = x / y
except ValueError as e:
    print("Error:", e)


# Corrected version
def divide(x, y):
    if y == 0:
        raise ValueError("y cannot be zero")
    return x / y
try:
    result = divide(x, y)
except ValueError as e:
    print("Error:", e)
else:
    print("Result:", result)

# Debugging steps to fix the error 
try: 
    if y == 0: 
        raise ValueError("y cannot be zero") 
    result = x / y 
except ValueError as e: 
    print("Error:", e) 

The code block above demonstrates the steps to fix the error by checking for a zero division condition and raising a ValueError with a meaningful error message.

# Corrected version:
def divide(x, y): 
    if y == 0: 
        raise ValueError("y cannot be zero") 
    return x / y 
try: 
    result = divide(x, y) 
except ValueError as e: 
    print("Error:", e) 
else: 
    print("Result:", result) 

The code block above provides the corrected version of the code using a divide function that includes the fix. It also includes error handling to catch and handle any exceptions, and it prints the result if there are no errors.
