Python - 不支持的操作数类型为 - ：'int'和'str'

Question

所以我正在研究一个小的轮盘程序，当我尝试添加/添加到用户余额时，它会出现错误已被标题，是什么让程序做到这一点，我该如何解决它？

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)) 

只是让这个帖子并没有得到下投票，我想再次重申，当我试图操纵在底部的if/elif的语句平衡可变我的问题是发生！

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，使整数与整数匹配。算术。
