Question

第6行怎么了？

 name = (input('Hi, please enter your name '))
dob = int(input('Hi please enter your DOB '))
today = int(input("Hi please enter today's date "))
future = int(today + 5)
diff = str(future - dob)
print ('Hi ' + name + 'in the year of ' + future + 'you will turn ' + diff)

我不断收到错误消息：

TypeError: must be str, not int

你们一般如何调试？我是编程新手。有没有办法确切知道它要在哪里字符串？

Answer 1

Python无法自动将整数变量转换为字符串。

您需要像这样将future变量显式转换为str类型：

print ('Hi ' + name + 'in the year of ' + str(future) + 'you will turn ' + diff)

Answer 2

future是整数，因此不能与字符串连接。您可以这样做：

print ('Hi ' + name + 'in the year of ', future, 'you will turn ' + diff)

或将int强制转换为str

print ('Hi ' + name + 'in the year of ' + str(future) + 'you will turn ' + diff)

示例：

name = (input('Hi, please enter your name '))
dob = int(input('Hi please enter your DOB '))
today = int(input("Hi please enter today's date "))
future = int(today + 5)
diff = str(future - dob)
print ('Hi ' + name + 'in the year of ', future, 'you will turn ' + diff)

输出：

C:\Users\Documents>py test.py
Hi, please enter your name job
Hi please enter your DOB 1876
Hi please enter today's date 2018
Hi jobin the year of  2023 you will turn 147

示例：

name = (input('Hi, please enter your name '))
dob = int(input('Hi please enter your DOB '))
today = int(input("Hi please enter today's date "))
future = int(today + 5)
diff = str(future - dob)
print ('Hi ' + name + 'in the year of ' + str(future) + 'you will turn ' + diff)

输出：

Hi, please enter your name job
Hi please enter your DOB 1876
Hi please enter today's date 2018
Hi jobin the year of 2023you will turn 147

TypeError：必须为str，而不是int Python3问题
