Question

I have this;

import operator
cuts = { "Emerald" : (10,125),
         "Oval" : (20,150),
         "Pear" : (35, 175),
         "Plumbbob" : (50,200),
         "Marquis" : (75, 230),
         "Crystal Ball" : (100, 260),
         "Brilliant" : (250, 350),
         "Star Cut" : (400,400),
         "Heart-shaped" : (1000, 500)
         }

def best(amount):
    "Returns most profitable cut's name."
    max_name = ""
    max_value = -10000
    for k,v in cuts.iteritems():
        value = ((float(amount) * (v[1] - 100) / 100)) - v[0]
        if value > max_value:
            max_value = value
            max_name = k
    return max_name

def create_table():
    """Creates a table like

       0-40 emerald
       40-45 Oval
       ...
       2000 + Heart-shaped
    """

But I am stuck at writing create_table. This code is for helping with a game I am playing. best funciton, given an amount, returns most profitable cut name for that amount. I want to create a table that shows me ranges. For example, for amounts between 0-40, best cut is emerald, between 40-45 best cut is Oval etc.

Answer 1

def create_table():
    curname = None
    for amount in xrange(2500):
        name = best(amount)
        if name != curname:
            if curname is not None:
                print "%d-%d %s" % (minamt, amount-1, curname)
            curname = name
            minamt = amount
    print "%d-%d %s" % (minamt, amount-1, curname)

(not tested, btw)
