TypeError：+ =不支持的操作数类型：'method'和'int'（Python） [英] TypeError: unsupported operand type(s) for +=: 'method' and 'int' (Python)

问题描述

我正在控制台中制作一个小型游戏，历时数天。游戏首先将矿工的矿石和金钱金额初始化为0。当他进行开采时，我的函数会选择一个介于20到71之间的随机整数，然后将其奖励为矿石。我正在尝试将已开采的矿石分配给玩家的矿石量。我遇到一个经常发生的错误，指出+ =是方法和整数的不受支持的操作数。完整的代码和跟踪信息如下。

I am making a small game in the console that takes place over several days. The game starts by initializing the miners ore and money amounts as 0. When he mines, my function chooses a random integer between 20 and 71 that will then award him that amount in 'ore'. I am trying to assign the ore that has been mined to my player's ore amount. I am having a reoccurring error that states that += is an unsupported operand for method and int. Full code and trace is below.

代码

import pyautogui as pag
import time
import sys
import random


class Miner:
    def __init__(self, oreDeposit, moneyDeposit):
        self.oreAmount = oreDeposit
        self.moneyAmount = moneyDeposit

    def oreDeposit(self, oreAmount):
        self.oreDeposit += oreAmount

    def oreWithdraw(self, oreAmount):
        self.oreWithdraw -= oreAmount
# -------------end of ore

    def moneyDeposit(self, moneyAmount):
        self.moneyDeposit += moneyAmount

    def moneyWithdraw(self, moneyAmount):
        self.moneyWithdraw -= moneyAmount
# -------------end of money

    def oreBalance(self):
        return self.oreAmount

    def moneyBalance(self):
        return self.moneyAmount
# -------------end of balances

def miningAction():
    x = random.randint(20, 71)
    for i in range(x):
        time.sleep(0.1)
        print(i)
        oreRecovered = i
        player.oreDeposit(oreRecovered)

player = Miner(0, 0)
miningAction()
print (player.oreAmount)

推荐答案

self.moneyDeposit 是对 moneyDeposit 的引用方法，并且不能将其递增一个数字（即使可以，也不会执行您想要的操作）。

self.moneyDeposit is a reference to the moneyDeposit method and it cannot be incremented by a number (and even if it could, it wouldn't do what you want it to do).

您应该更改

def moneyDeposit(self, moneyAmount):
    self.moneyDeposit += moneyAmount

def moneyWithdraw(self, moneyAmount):
    self.moneyWithdraw -= moneyAmount

into

def moneyDeposit(self, moneyAmount):
    self.moneyAmount += moneyAmount

def moneyWithdraw(self, moneyAmount):
    self.moneyAmount -= moneyAmount

和其他方法类似。
