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))
else:
print('对不起，你的余额不足！请努力工作吧！')
print('你当前所购买的商品为：')
for brought in shoppingList:
pprint.pprint(brought)
print('你当前余额为：', salary)
exit()
else:
print('你输入的商品序号有错，请重新输入')
elif userWant == 'q':
print('-----------Shopping List----------')
for brought in shoppingList:
pprint.pprint(brought)
print('你的余额为 ', salary)
exit()
