APPLE OF MY EYE TASK - HELP

Question

What is wrong with my code???

data = [
[23, 11, 5, 14],
[8, 32, 20, 5]
]
color = input()
#your code goes here

a=[x[0] for x in data]
b=[x[1] for x in data]
c=[x[2] for x in data]
d=[x[3] for x in data]

brown = a
blue = b
green = c
black = d

brown_1 = sum(a)
blue_1 = sum(b)
green_1 = sum(c)
black_1 = sum(d)

listSum = [sum(x) for x in data]
listSum2 = sum(listSum)

if color == a :
print (int((brown_1/listSum2)*100))
elif color == b :
print (int((blue_1/listSum2)*100))
elif color == c :
print (int((green_1/listSum2)*100))
elif color == d :
print (int((black_1/listSum2)*100))

Hi, stefano sartori !

What are you trying to do with this line in your code?

a = [x[0] for x in data]

This comprehension says that all datas element x are lists (or tuples or strings) and for every element x in data, you take out its first element and make a new list of it. But data is a list with just integers as element in your code, so this wont work.

So if:
data = ["snake", [9, 5, 0], (22, 44, 66)]

a = [x[0] for x in data]

Will give that:

=> a = ['s', 9, 22]
