我的代码有一个错误，我只是想不通[重复]

Question

代码：

current = input (" Now subtract it by 1. Uh-Oh, My calculator is broken, please tell me what the difference is.")
current = int(current)

print (" OK, my calulator is up and running. We must multiply the number  with 13. Its alright, I have the answer here.")
print (current*13 + " is the product") 

错误信息：

Traceback (most recent call last):
File "/home/pi/Desktop/birthday trick.py", line 13, in <module>
print (current*13 + " is the product")
TypeError: unsupported operand type(s) for +: 'int' and 'str'

请告诉我我可以做些什么来改进我的代码。

Answer 1

错误unsupported operand type(s) for +: 'int' and 'str' 表示 Python 无法将字符串添加到整数。在这种情况下，current 是一个整数，" is the product" 是字符串。

要解决此问题，您可以执行以下操作：

print("%d is the product"  % current  * 13)
