Question

Python 3.7.2 for language

Please comment for each line of code

good naming is important

1. Answer the question: what is the Python regular expression pattern that would match a hex color (https://en.wikipedia.org/wiki/Web_colors ) (for example, the pattern that would match an email address is '[\w.-]+@[\w.-]')

2. Write an algorithm for step 3. As part of your algorithm, be sure to describe the pattern you're using to find the win/loss result for each game.

3. Write a program that looks at the source of http://cgi.soic.indiana.edu/~dpierz/mbball.html (http://cgi.soic.indiana.edu/~dpierz/mbball.html ) (a copy of the IU men's basketball team record page). Use regular expressions to find all the games IU has played in this year and calculate the total number of wins and losses (including exhibition games)

     The output should look like the following:

Wins: 18
Losses: 12

Bonus [10 pts]. Extend your code from part 3 to also calculate the total difference in points scored in all the games (a game that finished 68-71 would have a difference of 3 points, 85-52 a difference of 33 points etc)

Total Difference: 431

Remember, as always good coding practices are part of the grade so be sure to comment your code, use good variable names, efficient regular expressions, etc.

Answer 1

Answer 1:

Regular Expression to use is:

match = re.search(r'^#(?:[0-9a-fA-F]{3}){1,2}$', str)

#Code to use

def Find_regex():
    import re
    str = '#80800' #Enter your hexadecimal
    """Check the regular expression"""
    match = re.search(r'^#(?:[0-9a-fA-F]{3}){1,2}$', str)
    if match:                    
      print ('Valid')
    else:
      print ('Invalid')
Find_regex()

Solution 2:

import re, urllib.request

"""Open the webpage"""
web_open = urllib.request.urlopen('http://cgi.soic.indiana.edu/~dpierz/mbball.html')
contents = web_open.read().decode(errors = "replace")
web_open.close()
result = []
win = 0
lose = 0
"""Use the regex"""
games_all = re.findall("(?<=div class='schedule_game_results'><div>).*?(?=</div>)", contents)
"""Calculate win lose"""
for i in games_all:
    if "W" in i:
        win += 1
    elif "L" in i:
        lose += 1
print("Wins: ", win)

print("Loses: ", lose)

points = 0
#import pdb;pdb.set_trace()
#games = games.replace(str(games[1]),'')
"""Bonus Point Question"""
for game in games_all:
    if game == games_all[1]:
        continue
    else:
        if game:
            first_score = game[2:4]
            second_score = game[5:7]
            points += abs(int(first_score) - int(second_score))
print("Total Difference: ", points)
