Python - 不支持的操作數類型爲 - ：'int'和'str'

Question

所以我正在研究一個小的輪盤程序，當我嘗試添加/添加到用戶餘額時，它會出現錯誤已被標題，是什麼讓程序做到這一點，我該如何解決它？

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)) 

只是讓這個帖子並沒有得到下投票，我想再次重申，當我試圖操縱在底部的if/elif的語句平衡可變我的問題是發生！

您的betAmount應聲明爲int(input("How much would you like to bet?\n"))以使其成爲整數。並如評論，使整數與整數匹配。算術。
