write a python code for addition of two matrix

r=int(input("enter number of rows:"))
c=int(input("enter number of column:"))
matrix[]

A=[[11,12,13],
   [14,15,16],
   [17,18,19]]
   
B=[[1,2,3],
   [4,5,6],
   [7,8,9]]
   
   
result=[[0,0,0],
        [0,0,0],
        [0,0,0]]
        
for i in range(len(A));
  for j in range(len(A[0])):
  result[i][j]=A[i][j]+B[i][j]
   
   for r in result:
   print(r)
