Dictionaries — Question 4

Question 4

Repeatedly ask the user to enter a team name and how many games the team has won and how many they lost. Store this information in a dictionary where the keys are the team names and the values are lists of the form [wins, losses].

(a) Using the dictionary created above, allow the user to enter a team name and print out the team's winning percentage.

(b) Using the dictionary, create a list whose entries are the number of wins of each team.

(c) Using the dictionary, create a list of all those teams that have winning records.

Solution

d = {}
ans = "y"
while ans == "y" or ans == "Y" :
    name = input("Enter Team name: ")
    w = int(input("Enter number of wins: "))
    l = int(input("Enter number of losses: "))
    d[name] = [w, l]
    ans = input("Do you want to enter more team names? (y/n): ")

team = input("Enter team name for winning percentage: ")
if team not in d:
    print("Team not found", team)
else:
    wp = d[team][0] / sum(d[team]) * 100
    print("Winning percentage of", team, "is", wp)
 
w_team = []   
for i in d.values():
    w_team.append(i[0]) 

print("Number of wins of each team", w_team)

w_rec = []
for i in d:
    if d[i][0] > 0:
        w_rec.append(i)

print("Teams having winning records are:", w_rec)
