# COndition:
#Write a program that reads a matrix from the console and prints:
# •   The sum of all numbers in the matrix
# •   The matrix itself
# On the first line, you will receive the matrix sizes in the format "{rows}, {columns}". On the next rows, you will get elements for each column separated by a comma and a space ", ".
#
# Input:
# 3, 6
# 7, 1, 3, 3, 2, 1
# 1, 3, 9, 8, 5, 6
# 4, 6, 7, 9, 1, 0
#
# Output:
# 76
# [[7, 1, 3, 3, 2, 1], [1, 3, 9, 8, 5, 6], [4, 6, 7, 9, 1, 0]]
