Question

Define a python function that is passed a table (2D list of lists) of integers and returns the total of all the integers in the table.

def total(T):

"""" Returns the sum of all the elements in the integer table T"""

Expert Solution

Explanation

Here I have created a function named total().

In this function, I have used for loop to iterate over the 2D list.

Inside the loop, I have used sum() method to get the sum of the current 1D list and added it total.

Then, I have returned the total sum of the list.

In the main block, I have created the 2D list with random numbers and then called the function total() inside the print statement to get the result to the console.
