Soccer - league table, old v new point system

# Soccer - league table, old v new point system

# Here is a sample line of data ...
# Always a good idea to have a sample as a comment to help you read what the program does

# 13 Queens Park Rangers 15 1 4 2 3 0 5 -11 16

# define any functions / methods we will need later
# JUST a definition - they're not run at this time!

def bypoints(this,that):
        return teamstats[that] - teamstats[this]

# Set up an empty "dictionary" called teamstats. As a dictionary, the indexes can be anything
# and we will use team names. We're going to store the number of points under the old scheme
# as the values

teamstats = {}

# Open the file of soccer data statistics

fh = open("soccer.data","r")

# Read each line of the data in turn into the variable called team

for team in fh:

        # take the trailing newline character off with strip.
        # then break the line into individual components with split (tab separated data)
        # store each value you get back into a separate variable - names as listed

        position,name,played,homewins,homedraws,homelosses,awaywins, \

        # store it into the teamstats dictionary we created earlier
