Question

I need help fixing a python code:

matrixA = []
matrixB = []
matrixC = []

N = 0

while(True):
N = int(input())

if(N < 2):
print("\nN must be >= 2\n")
continue
else:
break

a = list(map(int, input().split()))
matrixA.append(a)

for i in range(N):
b = list(map(int, input().split()))
matrixB.append(b)

for i in range(1):
for j in range(N):
s = 0
for k in range(N):
s += (matrixA[i][k] * matrixB[k][j])
matrixC.append(s)

for e in matrixC:
print(e, end = " ")

A matrix is a rectangle of numbers in rows and columns. A 1xN matrix has one row and N columns. An NxN matrix has N rows and N
columns.
Multiplying a 1xN matrix A and an NxN matrix B produces a 1x matrix C. To determine the Nth element of C multiply the each element of
A by each element of the Nth column of B and sum the results. Helpful information can be found at matrix multiplication.
Write a program that reads a 1x matrix A and an NxN matrix B from input and outputs the 1x matrix product, C. N can be of any size >

.
A is represented as a list of the integers found on the first line of ingut.
B is represented as a list of N rows, each of which is a list of Nintegers.
Each of the next Ningut lines contains the integers for one row of B
Note: Input is one row at a time but multiplication uses columns of B.
For coding simplicity, follow each output intagar by a space, even the last one. The output ends with a newline.
Ex If the input is
23

A contains 2 and 3, the first row of B contains 1 and 2, and the second row of B contains 3 and 4. The first element of Cis (21)+(3*3),
and the second element of Cis (2*2)+(3 * 4). The program output is
