## Python List: Exercise - 87 with Solution

Write a Python program to read a matrix from console and print the sum for each column. Accept matrix rows, columns and elements for each column separated with a space(for every row) as input from the user.

Sample Solution:

Python Code:

``````rows = int(input("Input rows: "))
columns = int(input("Input columns: "))
matrix = [*columns for row in range(rows)]
print('Input number of elements in a row (1, 2, 3): ')
for row in range(rows):
lines = list(map(int, input().split()))
for column in range(columns):
matrix[row][column] = lines[column]

sum = *columns
print("sum for each column:")
for column in range(columns):
for row in range(rows):
sum[column] += matrix[row][column]
print((sum[column]), ' ', end = '')
```
```

Sample Output:

```Input rows:  2
Input columns:  2
Input number of elements in a row (1, 2, 3):
1 2
3 4
sum for each column:
4  6
```
