Python - 'int'と 'str'のためのサポートされていないオペランドタイプ

Question

私は小さなルーレットプログラムで作業しています。ユーザーの残高を取得/追加しようとすると、タイトルが付けられたエラー、プログラムでこれを行うもの、どうすれば修正できますか？

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)) 

だけので、このポストは、ダウン投票取得していない、私は一番下にあるのif/elifのステートメントでバランス変数を操作しようとすると、私の問題が発生している、反復処理を再度したいと思います！

betAmountは整数にするにはint(input("How much would you like to bet?\n"))と宣言してください。そしてコメントとして、整数を整数と一致させる。算術的に。
