Python Programming with the Java™ Class Libraries: A Tutorial for Building Web and Enterprise Applications with Jython

Putting It All Together

Now it's time to create a program that uses everything we've learned so far. This program will generate a list of house prices and find their average (mean, mode, and median) and range. The following sections will describe each function in turn.

getRange()

getRange() iterates through a set of numbers passed to it and calculates the minimum and maximum values. It then returns these values and their range in a tuple.

def getRange (nums):
       min = 300000000
       max = -300000000
for item in nums:
       if (item > max): max = item
       if (item < min): min = item

return (min, max, max-min)

First getRange() declares two variables, min and max. The min variable refers to a very large number, so the first item extracted from the list is less ...
