How to edit the self.TeamScore value in my code

I am trying to make a leaderboard for a school tournament. I began asking the user to input some team names and how many members in the team. Now i want to be able to ask the user; ‘who won the game?’ and then adjust that teams score by 1.

How can i change a teams score based on the users input?

class AllTeams:
  def __init__(self, TeamNum, TeamName, TeamMembers,    TeamScore):
    self.TeamNum = TeamNum
    self.TeamName = TeamName
    self.TeamMembers = TeamMembers
    self.TeamScore = TeamScore

  def __repr__(self):
    return f'Team Number: {self.TeamNum} |-| Team Name: {self.TeamName} |-| Member Count: {self.TeamMembers} |-| Team Score: {self.TeamScore}'

#teams = [AllTeams(i+1, "N/A", 0) for i in range(20)]
teams = []

TeamCounter=int(input('How many Teams will be in the tournament? '))

print('')
for i in range(TeamCounter):
    NameOfTeam=input(f'Please Enter Team {i+1} Name: ')
    MemberCount=input('How Many Members in Team? ')
    print('')
    teams.append( AllTeams( i+1, NameOfTeam, MemberCount, 0) )

def score():
    for t in teams:
    print(t)

    GameWinner=input('Which Team Won the Event? ')

    #change team score by 1

>Solution :

You need to iterate on the teams to find the one with the good name to update hi score

def score(teams):
    winner = input('Which Team Won the Event? ')
    for team in teams:
        if team.name == winner:
            team.add_victory()
            break

Then a few better naming and the class becomes

class Team:
    def __init__(self, num, name, size, score):
        self.num = num
        self.name = name
        self.size = size
        self.score = score

    def add_victory(self):
        self.score += 1

    def __repr__(self):
        return f'Team Number: {self.num} |-| Team Name: {self.name} |-| Member Count: {self.size} |-| Team Score: {self.score}'
