while True:

for index, item in enumerate(productList):

print(index + 1, item)

print('输入你要买的商品的序号:')

userWant = input()

if userWant.isdigit():

userWant = int(userWant)

if userWant <= len(productList) and userWant > 0:

print('你要购买的是:', productList[userWant - 1][0])

if salary >= productList[userWant - 1][1]:

shoppingList.append(productList[userWant - 1][0])

salary -= productList[userWant - 1][1]

print('你已经购买了' + productList[userWant - 1][0] + ', 你的余额为 ' + str(salary))
