【问题描述】：

我尝试创建类并定义其对象以找到总和和平均值但代码不起作用。我已经制作了 CricketGame 类并创建了模型和对象，但代码仍然无法正常工作。谁能让我更清楚地了解如何使用类对象和模型。

class CricketGame:
    def __init__(self, name, age, matches, innings, runs_scored, wickets_taken, ball_faced, runs_given, ball_bowled):
        self.name = name
        self.age = age
        self.matches = matches
        self.innings = innings
        self.runs_scored = runs_scored
        self.wickets_taken = wickets_taken
        self.ball_faced = ball_faced
        self.runs_given = runs_given
        self.ball_bowled = ball_bowled

    def playerstat(self):
        batting_average = self.runs_scored/self.innings
        batting_strike_rate = self.runs_scored/self.ball_faced
        bowling_average = self.ball_bowled/self.wickets_taken
        bowling_strike_rate = self.runs_given/self.wickets_taken

    def playerresult(self, batting_average, batting_strike_rate, bowling_average, bowling_strike_rate):
        print "Batting Average : ", batting_average
        print "Batting Strike Rate : ", batting_strike_rate
        print "Bowling Average : ", bowling_average
        print "Bowling Strike rate : ", bowling_strike_rate

    def playerinfo(self):
        print "Player's Name : ", self.name
        print "Age : ", self.age
        print "Matches : ", self.matches
        print "Inning Played :", self.innings
        print "Run Score : ", self.runs_scored
        print "Wicket Taken :", self.wickets_taken
        print "Ball Faced :", self.ball_faced
        print "Runs Given : ", self.runs_given
        print "Ball Bowled : ", self.ball_bowled


name = raw_input("Enter the name of the player : ")
age = input("Enter the age of the player : ")
matches = input("Enter the number of matches played : ")
innings = input("Enter the innings played : ")
runs_scored = input("Enter total runs scored: ")
wickets_taken = input("Enter the total wickets taken : ")
ball_faced = input("Enter the total number of ball faced : ")
runs_given = input("Enter the total runs given : ")
ball_bowled = input("Enter the total ball bowled : ")

player = CricketGame(name, age, matches, innings, runs_scored, wickets_taken, ball_faced, runs_given, ball_bowled)
player.playerinfo()
player.playerstat()
player.playerresult()

标签： python class object sum average

【解决方案1】：

playerresult() 函数需要 4 个参数，你传递了 0 个参数。当您在 playerstat() 中计算 batting_average 时，它不会传递给 playerresult() 函数。您可以将这些变量转换为实例变量，以便从其他方法访问它们。

    def playerstat(self):
        self.batting_average = self.runs_scored/self.innings
        self.batting_strike_rate = self.runs_scored/self.ball_faced
        self.bowling_average = self.ball_bowled/self.wickets_taken
        self.bowling_strike_rate = self.runs_given/self.wickets_taken

    def playerresult(self):
        print "Batting Average : ", self.batting_average
        print "Batting Strike Rate : ", self.batting_strike_rate
        print "Bowling Average : ", self.bowling_average
        print "Bowling Strike rate : ", self.bowling_strike_rate

【解决方案2】：

player.playerstat() 创建并“忘记” 4 个变量，因为您没有保存它们。您可以在 player.playerstat() 中返回您正在计算的内容并将其分配给 4 个变量。然后将这些变量作为参数传递给player.playerresult()。

另一种方法是将这 4 个变量保存为对象的属性（self.batting_average 等）并更改player.playerresult()，使其不接受任何参数，而是打印self.batting_average 等。
