The command sum does not work in a matrix, how do I add all the numbers correctly?

Question

data = [
[23, 11, 5, 14],
[8, 32, 20, 5]
]

I want to add all the numbers in data

Answer 1

Alba Robledo ,

can you please share us your attempt?

here some hints how it can be done:

> we can use itertools chain, then do summing

> if there are more nested levels than 2, it makes sense to create a general flatten() function , then do summing

Answer 2

print(sum(data[0]) + sum(data[1]))

Answer 3

sum([sum(num_list) for num_list in data])

Answer 4

Have a look at the numpy module: It has an array data type that allows calculating sums and much more

Answer 5

total = sum(map(sum, data))

Answer 6

Solved, thanks all
