Plotting Help

[Joey7]

Hello All,
I'm working on my first Python plot in my programming class this week.
My assignment is to write a program to plot data contained in a csv format.
Here is the data:
"Bowl number", "Date", "Bowl location", "Winner", "Number wings eaten"
"I", "1/29/1993", "Wyndham Franklin Plaza Hotel", "Carmen ’The Beast From the East’ Cordero", 100
"II","1/28/1994", "The Main Event", "Kevin ’Heavy Keavy’ O"Donnell", 127
"III", "1/27/1995", "Club Egypt", "Kevin ’Heavy Keavy’ O"Donnell""", 133
"IV","1/26/1996","Electric Factory","Glen ’Fluffmaster’ Garrison", 155
"V", "1/24/1997", "Electric Factory", "Eric ’Gentleman E’ Behl", 120
"VI","1/23/1998","Spectrum","Mark ’Big Rig’ Vogeding", 164
"VII", "1/29/1999", "Spectrum", "Bill ’El Wingador’ Simmons", 113
"VIII", "1/28/2000", "First Union Center","’Tollman Joe’ Paul", 90
"IX","1/26/2001","First Union Center", "Bill ’El Wingador’ Simmons", 137
"X", "2/1/2002", "First Union Center", "Bill ’El Wingador’ Simmons", 135
"XI","1/2/2003","First Union Center", "Bill ’El Wingador’ Simmons",154
"XII", "1/30/2004", "Wachovia Center", "Sonya ’The Black Widow’ Thomas", 167
"XIII", "2/4/2005", "Wachovia Center", "Bill ’El Wingador’ Simmons", 162
"XIV", "2/3/2006", "Wachovia Center", "Joey Chestnut", 173
"XV","2/2/2007","Wachovia Center", "Joey Chestnut",182
"XVI", "2/1/2008", "Wachovia Center", "Joey Chestnut",241
"XVII", "1/30/2009", "Wachovia Center", "Jonathan ’Super’ Squibb",203
"XVIII", "2/5/2010", "Wachovia Center", "Cassandra ’Wings’ Gillig", 238
"XIX", "2/4/2011", "Wells Fargo Center", "Jonathan ’Super’ Squibb", 255

My x axis has to look like this "I ('93)" "II ('94)" etc.
My y axis is just the number of wings.
I have to keep my program like it is layed out for the assignemnt to
be correct, but I'm getting an error "ValueError: x and y must have
same first dimension"
There are a few other kinks in the program that I can't figure out.
This is my program so far:

import matplotlib.pyplot as plot 
import numpy as np 
def make_line_plot(wing_bowl,wings_eaten): 
    fig = plot.figure ( figsize =(20 ,5)) 
    x_label_pos = range(len(wing_bowl)) 
    plot.plot(x_label_pos, wings_eaten, color='blue', marker= 'o') 
    plot.title('Wing Bowl Contest Results') 
    plot.xlabel("Wing Bowl") 
    plot.ylabel('Number of wings eaten') 
    plot.grid('True') 
    plot.xticks(x_label_pos,wing_bowl) 
    plot.yticks(range(0,300,50)) 
    plot.autoscale(enable=True, axis='x',tight=True) 
    fig.autofmt_xdate() 
    plot.savefig('wing-bowl-results.pdf') 
def main(): 
    input_file=open('wing-bowl-data.csv') 
    input_file.readline() 
    lines=input_file.readlines() 
    wingbowl=[] 
    wings=[] 
    for line in lines: 
        split_line=line.strip().split(',') 
        wingbowl+=split_line[0] 
        wings+=[float(split_line[4])] 
    make_line_plot(wingbowl,wings) 
main()

Any help would be greatly appreciatated!
Thanks,
Joey
