# Python Program to Find the Sum of Each Row and Each Column of a Matrix

__Python__ program to find the sum of each row and each column of a matrix.

In this article, you will learn how to make a python program to find the sum of each row and each column of a matrix.

### Example

**-----Enter the number of rows & columns of the matrix-----
4
3**

**-----Enter the coefficients of the matrix-----
12
23
12**

**34
12
43**

**34
53
12**

**56
34
23**

**The Sum of the 0 position row is = 47
The Sum of the 1 position row is = 89
The Sum of the 2 position row is = 99
The Sum of the 3 position row is = 113**

**The Sum of the 0 position column is = 136
The Sum of the 1 position column is = 122
The Sum of the 2 position column is = 90**

You should have the knowledge of the following topics in python programming to understand these programs:

- Python

function**input()** - Python For loop

### Source Code

```
# Python Program to Find the Sum of Each Row and Each Column of a Matrix
print ("-----Enter the number of rows & columns of the matrix-----")
# These are the matrix's dimension
x = int (input ())
y = int (input ())
a, sum = [], 0
print ("\n-----Enter the co-efficients of the matrix-----")
for i in range (x):
a.append([])
for j in range (y):
a[i].append(int (input ()))
print (end="\n")
# This statement will compute the
# sum of the matrix's rows elements
for i in range (x):
for j in range (y):
sum = sum + a[i][j]
print ("The Sum of the ", i, " position row is = ", sum)
sum = 0
print (end="\n")
sum = 0
# This statement will compute the
# sum of the matrix's columns elements
for j in range (y):
for i in range (x):
sum = sum + a[i][j]
print ("The Sum of the ", j, " position column is = ", sum)
sum = 0
```

### Output

`-----Enter the number of rows & columns of the matrix-----`

`The Sum of the 0 position row is = 47`

The Sum of the 1 position row is = 89

The Sum of the 2 position row is = 99

The Sum of the 3 position row is = 113

`The Sum of the 0 position column is = 136`

The Sum of the 1 position column is = 122

The Sum of the 2 position column is = 90

### Explanation

In this given program, we have taken the inputs size of matrix rows and columns

and **4**

then we collected coefficient values of the matrix from the user via the system console.**3**

Then we applied for loop on this matrix twice a time to make the sum of its coefficients row-wise and column-wise.

Then this will return the final output of these sums row-wise

, **47**

, **89**

, and **99**

& column-wise are **113**

, **136**

, and **122**

of the above program.**90**
