这是错误

Traceback (most recent call last):
  File "G:\Computer Science\Python\Car Salesman Program Example.py", line 16, in <module>
    print ("The price of the car is now: "),(base * tax / 100)+(base*license /100)+ base + dealer_prep + destination_charge
TypeError: unsupported operand type(s) for /: 'str' and 'int'

这是程序

#Car salesman calculations program.
#The user enters the base price of the car and the program adds tax, license (which are both a percentage
#of the base price),dealer prep and destination charge. It then displays the final price. 

base = input("What is the base price of the car? ")

tax = 7

license = 4

dealer_prep = 500

destination_charge = 1000


print ("The price of the car is now: "),(base * tax / 100)+(base*license /100)+ base + dealer_prep + destination_charge

Answer 1

您正在连接字符串，＆＃34;价格......＆＃34;，整数。您需要使用str（）函数将整数转换为字符串。

print ("The price of the car is now: "),
    str( (base * tax / 100)+(base*license /100)+ base + dealer_prep + destination_charge )

Answer 2

您的变量base是一个字符串，因此您无法使用base进行计算，直到将其转换为整数：

base = int(input("What is the base price of the car? "))

我的python程序出错了，我不知道出了什么问题？
