First read the input from the command line (hint : use sys.argv). Also you will need to figure out how to convert strings to python numbers. Then check if b**2-4*a*c < 0. If yes, then raise a ValueError about that there are no real roots. Else solve for the roots: roots = (b ± sqrt(b**2-4*a*c)) … Read more

a.strip().split() produces a list of strings of the form ‘a-b’ where the a and b are composed of digit characters. This means that: alignment = set([tuple(map(int, x.split(“-“))) for x in a.strip().split()) produces a set from a list defined by a list comprehension. The list comprehension takes each of these ‘a-b’ strings, spits it into two … Read more
