Work for capital markets academy today, looking at Vector class and Schedular class so far.

scheduler.py

#!/usr/bin/env python


class Scheduler():
    event = ""
    dow = ""
    dow_list = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday",
                "Friday", "Saturday"]

    def __init__(self, event, dow):
        self.event = event
        self.dow = dow

    def returnindex(self):
        return (self.dow_list.index(self.dow))

    def getevent(self):
        return self.event

    def __str__(self):
        return str(self.event)

    def __cmp__(self, other):
        if (self.returnindex() < other.returnindex()):
            return(-1)
        elif (self.returnindex() == other.returnindex()):
            return(0)
        else:
            return(1)

s = Scheduler("Party at Sara's", "Saturday")
s2 = Scheduler("Party at Harry's", "Friday")

if (s < s2):
    print s.getevent()
elif (s == s2):
    print s.getevent(), s2.getevent()
else:
    print s2.getevent()

vector.py

#!/usr/bin/env python


class Vector():
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def __add__(self, other):

    def __sub__(self, other):
        return (Vector(self.a - other.a, self.b - other.b))

    def __mul__(self, other):
        return (Vector(self.a * other.a, self.b * other.b))

    def __div__(self, other):
        return (Vector(self.a / other.a, self.b / other.b))

    def __str__(self):
        return 'Vector (%d, %d)' % (self.a, self.b)

vector1 = Vector(2, 4)
vector2 = Vector(3, 6)
vector3 = vector1 + vector2
print vector3 - Vector(1,2)
