How to take 2D array input in python

Python code implementation to take 2D array input. 

Code: 

column_size = int(input("Enter size of column: "))
row_size = int(input("Enter size of row: "))
a = []
for i in range(0, row_size):
    b = []
    for j in range(0, column_size):
        print("Input {0} {1} element of 2d array".format(i, j))
        temp = int(input())
        b.append(temp)
    a.append(b)
print("Print 2D array: ", a)

Value of column size entered: 4

Value of row size entered: 2

Output: The code executed to take input for all the elements of 2D array list and print the 2D array

Enter size of column: 4
Enter size of row: 2
