Question

1）这是错误消息：

Traceback (most recent call last):
  File "script.py", line 14, in <module>
    customer_one_tax = customer_one_total * sales_tax
TypeError: can't multiply sequence by non-int of type 'str'

2）这是一个变量：

sales_tax = '.088'

3）另一个变量CUSTOMER_ONE总计是最后一次更新的更新变量：

customer_one_total += luxurious_lamp_price

Answer 1

好像sales_tax是一个字符串。 '.088'-> str。也许尝试.088

Answer 2

错误非常明显：

can't multiply sequence by non-int of type 'str'

您的sales_tax = '.088'是string而不是number

并且：

>>>3*'.88'
'.88.88.88'
>>>'3'*'.88'
Traceback (most recent call last):
  File "/usr/lib/python3.6/code.py", line 91, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
TypeError: can't multiply sequence by non-int of type 'str'

您的customer_one_total似乎也不是“数字”

我的建议是float()

customer_one_total += float(luxurious_lamp_price)
customer_one_tax = customer_one_total * float(sales_tax)

我在代码中找不到类型错误？
