def card_average(hand): return sum(hand) / len(hand)
def average_even_is_average_odd(hand): evens = hand[::2] odds = hand[1::2] return card_average(evens) == card_average(odds)
I am expecting this function to return True if the average of the even-indexed elements in the list "hand" is equal to the average of the odd-indexed elements, and False if not. This is the error that's being thrown for every test:
TypeError: list indices must be integers or slices, not float
I have tried int() on every number but still nothing seems to work. Any suggestions?

Would you mind posing the whole code and whole error

That's the whole error, I posted the whole code

This error TypeError: list indices must be integers or slices, not float
come from somewhere else, that's why i ask for the whole code aka other functions as well
your implementation of those 2 functions already look correct. so this is likely from somewhere else

Oh thank you. You're right. It's from the previous exercise 🤦♂️
def approx_average_is_average(hand): average_first_and_last = (hand[0] + hand[-1]) / 2 middle_card_index = int((len(hand) + 1) / 2) median = hand[middle_card_index] return median == card_average(hand) or average_first_and_last == card_average(hand) pass
This is the one throwing the error
velvet creek
If there are 5 cards, what is the index of the middle card?

did everything pass now?
timid breach
Yeh all passed now. Thank you so much!

no problem, have fun coding!
