Python - 不支持的操作数类型 - : 'int' and 'str'

Question

所以我正在开发一个小轮盘赌程序，当我尝试获取/添加到用户余额时，它会出现标题为错误的错误，是什么让程序这样做以及如何解决它？

import random
import time

balance = 100

outcome = random.randint(0,17)
if outcome == 0:
    color = "GREEN"
elif outcome <=7:
    color = "RED"
else:
    color = "BLACK"

print("Current Balance: $"+str(balance))
colorChoice = input("Place your bet by typing either: RED, GREEN or BLACK\n")
colorChoice = colorChoice.upper()
betAmount = input("How much would you like to bet?\n")
if int(betAmount) > balance:
    print("Insufficient Funds")
else:
    print("** ROLLING **")
    time.sleep(2.5)
    print("The color landed on: " + color)
    if colorChoice == color and color == "GREEN":
        print("Win! Your balance has been adjusted!\nYou selected: " +     colorChoice + " and the spinner landed on: " + color)
        greenLand = betAmount * 14
        balance = balance + greenLand
    elif colorChoice == color and color == "RED":
        print("Win! Your balance has been adjusted!\nYou selected: " + colorChoice + " and the spinner landed on: " + color)
        balance = balance + betAmount
    elif colorChoice == color and color == "BLACK":
        print("Win! Your balance has been adjusted!\nYou selected: " + colorChoice + " and the spinner landed on: " + color)
        balance = balance + betAmount
    elif colorChoice != color and color == "GREEN":
        print("Loss! Your balance has been adjusted!\nYou selected: " + colorChoice + " and the spinner landed on: " + color)
        balance = balance - betAmount        
    elif colorChoice != color and color == "RED":
        print("Loss! Your balance has been adjusted!\nYou selected: " + colorChoice + " and the spinner landed on: " + color)
        balance = balance - betAmount        
    elif colorChoice != color and color == "BLACK":
        print("Loss! Your balance has been adjusted!\nYou selected: " + colorChoice + " and the spinner landed on: " + color)
        balance = balance - betAmount        
    print("New Balance: $" + str(balance))

为了不让这篇文章被否决，我想重申，当我尝试在底部的 if/elif 语句中操作 balance 变量时，我的问题出现了!

您的 betAmount 应声明为 int(input("How much would you like to bet?\n")) 以使其成为整数。并如评论所述，使整数与整数匹配。算术上。
