Python Taskbook Level 10.2

Write a program that will find the roots of a quadratic equation. To do this, ask the user for three numbers that will be the coefficients of the equation.

Print to the console a list of all excess numbers in a given range.

Given an arbitrary two-dimensional list:

[ [11, 12, 13], [21, 22, 23], [31, 32, 33], ]

Write some code that will add another column to the list filled with random values:

[ [11, 12, 13, 14], [21, 22, 23, 24], [31, 32, 33, 34], ]
