Error “…function For ‘xxx’ Did Not Return A Valid Response”

This error message usually occurs when a function in Python does not return a valid response or return statement is missing.

Here’s an example to illustrate this error:

def calculate_sum(num1, num2):
    result = num1 + num2
    # missing return statement

sum_result = calculate_sum(3, 4)
print(sum_result)

In this example, the function calculate_sum does not have a return statement. As a result, when we try to assign the function’s result to sum_result and print it, we will encounter the error message "function for ‘calculate_sum’ did not return a valid response".

To fix this error, you need to ensure that your function returns a value or a statement using the return keyword. For the above example, you could fix it like this:

def calculate_sum(num1, num2):
    result = num1 + num2
    return result  # Add return statement

sum_result = calculate_sum(3, 4)
print(sum_result)

Now, the function calculate_sum returns the result and the error should be resolved.
