python define matrix code example
Example: matrix using python
# A basic code for matrix input from user
# numpy is not used
R = int(input("Enter the number of rows:"))
C = int(input("Enter the number of columns:"))
# Initialize matrix
matrix = []
print("Enter the entries rowwise:")
# For user input
for i in range(R): # A for loop for row entries
a =[]
for j in range(C): # A for loop for column entries
a.append(int(input()))
matrix.append(a)
# For printing the matrix
for i in range(R):
for j in range(C):
print(matrix[i][j], end = " ")
print()
