Python – Checking the number of internal elements in a 3D string list

Question

We are working on counting the number of elements in the 3D string list and using that number.

eleli = [[["ele", "ele", "ele", "ele", "ele"], ["ele", "ele", "ele"]], [["ele", "ele", "ele", "ele", "ele"], ["ele", "ele", "ele", "ele"]], [["ele", "ele", "ele", "ele"], ["ele", "ele", "ele", "ele", "ele"]], [["ele", "ele"]]]

print(len(eleli))

>>>4

Is there a simple way to count all string elements in a list?

Answer 1

Yes, there is:

print(sum(len(e) for seq in eleli for e in seq))

Try something like the following:

eleli = [[["ele", "ele", "ele", "ele", "ele"], ["ele", "ele", "ele"]], [["ele", "ele", "ele", "ele", "ele"], ["ele", "ele", "ele", "ele"]], [["ele", "ele", "ele", "ele"], ["ele", "ele", "ele", "ele", "ele"]], [["ele", "ele"]]]

# Find the length of all primitive elements within the inner lists.

total = 0

for i in eleli:
    for j in i:
        total +=len(j)


print(total)
