I create a program,and it has a TypeError:"'int' object has no attribute 'getitem'"

Question

numberOfArray1 = [1, 2, 5, 3]
numberOfArray2 = [4, 1, 3, 2]

allNumber = []

for array1 in numberOfArray1:
    for array2 in numberOfArray2:
        for i in numberOfArray1:
            for j in numberOfArray2:
                addedNumber = array1[i] + array2[j]
                allNumber.append(addedNumber)

print allNumber

Why are you looping at 4 levels? array1 is already a number, so you are essentially doing 1[i] + 1[j]. — loganfsmyth

This line

for array1 in numberOfArray1:

iterates array1 through values of 1, 2, 5, and 3. Your reference to it later

addedNumber = array1[i] + array2[j]

is trying to treat array1 as an array; but it isn't. It's an integer, and cannot be subscripted like that. That's what 'int has no attribute getitem' means.

So do like that:

n1 = [1, 2, 5, 3]
n2 = [4, 1, 3, 2]
n = []
for i in range(0, len(n1)):
    n.append(n1[i] + n2[i])
print n
