Example: Multiplication of Two Matrix in Python of Same Dimensions using For loop

# Multiplication of Two Matrix in Python of Same Dimensions using For loop
x, y, m, r, c, i, j, k = [], [], [], 0, 0, 0, 0, 0

# r - Value of the number of rows
# c - Value of the number of columns

print ("Enter the number of rows & columns of the matrix::")
r = int (input ())
c = int (input ())

# x - To store first matrix elements
# y - To store second matrix elements
# m - To store multiplication of matrices

print ("\n---Enter the first matrix's elements---")

for i in range (r):
    x.append([])
    for j in range (c):
        x[i].append(int (input ()))

print ("\n---Enter the second matrix's elements---")

for i in range (r):

    for j in range (c):

print ("\n-----The multiplication of the matrices is-----\n")

# This will display matrices's outputs

    print ("\t", end="\t")
