Python Program to Add Two Matrices Using Nested Loop | Here, we will develop a Python program to add two matrices using nested loop. For adding any two matrices, both the matrices should be of the same dimension; we carry out the addition by adding corresponding elements together. Similar to the add operation, we can also implement other mathematical operations.
Add Two Matrices using Nested Loop in Python
A nested loop is a loop inside another loop. In this example, we use nested for-loops to add matrices.
Program description:- Write a python program to add two matrices using nested loop
# Python program to add two matrices using nested loop
r = int(input("Enter the rows: "))
c = int(input("Enter the columns: "))
print("Enter Matrix 1: ")
m1 = [[int(input()) for i in range(c)] for i in range(r)]
print("Matrix 1 is: ")
for n in m1:
print(n)
print("Enter Matrix 2: ")
m2 = [[int(input()) for i in range(c)] for i in range(r)]
for n in m2:
print(n)
r = [[0 for i in range(c)] for i in range(r)]
for i in range(len(r)):
for j in range(c):
r[i][j] = [m1[i][j] + m2[i][j]]
print("Add Matrix: ")
for i in r:
print(i)Output:-
Enter the rows: 2
Enter the columns: 3
Enter Matrix 1:
12
25
23
10
24
30
Matrix 1 is:
[12, 25, 23]
[10, 24, 30]
Enter Matrix 2:
25
36
42
10
15
20
[25, 36, 42]
[10, 15, 20]
Add Matrix:
[[37], [61], [65]]
[[20], [39], [50]]
In the above code, we have used a nested for loop to add m1 and m2. The outer loop reads the row elements the inner loop reads the column elements and stores the result in r.
