Python 3 Error: Need Help Resolving the Issue

Hello Python enthusiasts,

I hope everyone is having a productive day. I find myself stuck with an error in my Python 3 code and would greatly appreciate your insights and expertise in resolving this issue.

The error I am encountering arises when I execute the following code snippet:

Python 3 code snippet

def calculate_average(numbers):
    total = sum(numbers)
    average = total / len(numbers)
    return average

my_numbers = [10, 20, 30, 40, 50]
result = calculate_average(my_numbers)
print("The average is:", result)

The specific error message I receive is as follows:

Traceback (most recent call last):
  File "", line X, in <module>
    result = calculate_average(my_numbers)
  File "", line Y, in calculate_average
    average = total / len(numbers)
TypeError: unsupported operand type(s) for /: 'int' and 'str'

From the traceback, it appears that there is a problem with dividing an integer by a string. However, upon inspecting my code, I cannot identify where the string is coming from or how it is affecting the division operation.

To provide some context, my intention is to calculate the average of a list of numbers. While the logic seems correct, this error prevents me from obtaining the desired outcome.

If any of you have encountered a similar Python 3 error or have suggestions on how to resolve this particular issue, I would be grateful for your assistance. Any insights, explanations, or potential solutions would be greatly appreciated.

For your information, I am using Python version 3.X.X, and I am running this code on a [your operating system]. Additionally, I have confirmed that the my_numbers list does not contain any string elements.

Thank you all in advance for your support and valuable contributions. Your assistance will help me overcome this Python 3 error and continue with my project.

Best regards,

From the code you shared, it seems that there is nothing wrong. The function calculate_average correctly computes the average of a list of numbers, and my_numbers is a list of integers.

The error message you provided indicates that at some point, the division operation in the calculate_average function is trying to divide an integer by a string, which is causing a TypeError.

Given the code you provided, it’s unclear why this would happen, as you stated my_numbers contains only integers, not strings.

Therefore, I suspect the error might be coming from somewhere else in your code. Please make sure that you don’t call the calculate_average function somewhere else with a list that contains a string.

Alternatively, it’s possible that the list my_numbers is being modified somewhere else in your program to include a string.

Without more context or the full code, it’s difficult to diagnose the problem with certainty. I recommend checking the rest of your program carefully for any such issues. If you still can’t identify the problem, please provide the full code or more context so we can better assist you.

Hope this helps!
