python program to read a matrix code example

Example 1: how to get matrix element in the form of matrix in python

# A basic code for matrix input from user 
  
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()

Example 2: how to input 2-d array in python

matrix = [input().split() for i in range(no_of_rows)] # if only row is given and the number of coloumn has to be decide by user
matrix= [[input() for j in range(no_of_cols)] for i in range(no_of_rows)] # if both row and coloumn has been taken as input from user

Example 3: how to print a matrix in python

import numpy as np
print(np.matrix(A))
