The Nile Test Functions

Here is the link to the exercise I am working on:

https://www.codecademy.com/courses/learn-python-3/projects/function-args-the-nile

The code looks fine as it looks just like the walkthrough but for some reason it doesn’t register that I am telling it to expect multiple arguments. So when I run the test it says the following:

calculate_driver_cost() doesn’t expect multiple driver arguments

Here is my code, I don’t see what’s wrong.

def calculate_driver_cost(distance, *drivers):
cheapest_driver = None
cheapest_driver_price = None
for driver in drivers:
driver_time = driver.speed * distance
price_for_driver = driver.salary * driver_time
if cheapest_driver is None:
cheapest_driver = driver
cheapest_driver_price = price_for_driver
elif price_for_driver < cheapest_driver:
cheapest_driver = driver
cheapest_driver_price = price_for_driver
return cheapest_driver_price, cheapest_driver

Test the function by calling

test_function(calculate_driver_cost)

I actually completed the rest of the exercise and got the same error for the last part where we pass in a dictionary and need to use **args. There has to be some bug going on here. My code looks the same.

Hello, @xavierdavis869921579. Welcome to the forum! Could you post your code using the </> button, so we can see it in the way you have it formatted in the code editor? See the following regarding pasting code into a forum post:

Thanks!

In elif line, it should be price_for_driver< cheapest_driver_price

Hi,
I have the same problem

def calculate_driver_cost(distance,*drivers):
  cheapest_driver = None
  cheapest_driver_price = None
  for driver in drivers:
    driver_time = driver.speed * distance
    price_for_driver = driver.salary * driver_time
    if cheapest_driver is None:
      cheapest_driver = driver
      cheapest_driver_price = cheapest_driver_price
    elif price_for_driver < cheapest_driver_price:
      cheapest_driver = driver
      cheapest_driver_price = cheapest_driver_price
  return cheapest_driver_price, cheapest_driver

the test result is

calculate_driver_cost() doesn't expect multiple driver arguments

I have also been having the same issues.
calculate_driver_cost() doesn't expect multiple driver arguments calculate_money_made() doesn't expect multiple trip keyword arguments

I watched the video walkthrough and my code is essentially the same.
