The provided Python code has a few issues that need to be addressed. Here's the corrected version of the code along with explanations for the fixes:
pythondef calculate_average(nums): total = 0 if nums: # Check if the list is not empty for num in nums: total += num average = total / len(nums) return average else: return None # Return None if the list is empty numbers = [10, 20, 30, 40, 50] result = calculate_average(numbers) if result is not None: print("The average is:", result) else: print("The list is empty. Cannot calculate the average.")
Explanations:
-
Variable naming: In Python, it's generally considered a good practice to use more descriptive variable names to improve code readability. In the original code, the variable
sum
was used, which is a built-in function in Python and should be avoided as a variable name to prevent potential naming conflicts. The corrected code usestotal
instead. -
Handling empty lists: The original code did not handle the case where the input list
nums
is empty. Dividing by zero would raise aZeroDivisionError
in such cases. The corrected code checks if the listnums
is not empty before performing the calculations. If the list is empty, it returnsNone
to indicate that the average cannot be calculated. -
Printing the result: In the original code, there was a typo in the
print
statement. The variableresults
was misspelled and did not match the variable nameresult
returned by thecalculate_average
function. The corrected code fixes this typo. -
Handling the case when the average cannot be calculated: The corrected code checks if the
result
is notNone
before printing the average. Ifresult
isNone
, it means the input list was empty, and the code prints a message indicating that the average cannot be calculated.
With these fixes, the corrected code handles edge cases, follows best practices for variable naming, and provides a more robust and readable implementation of the calculate_average
function.
