代码为：

#!/usr/bin/python

# _*_ coding:utf-8_*_

# print("hello world!")

name = input("name:")

age = int(input("age:"))

print(type(age))

#print(type(age), type(str(age)))

home = input("home:")

print(type(home))

info3='''

---------info3 of ''' + name + ''' --------------

name: ''' + name + '''

age:''' + age + '''

home:''' + home + '''

--------end---------

'''

print(info3)

在使用python拼接进行格式化输出时出现如下错误：

Traceback (most recent call last):

  File "D:\linux\python\test2\day1\info.py", line 22, in <module>

    home:''' + home + '''

TypeError: can only concatenate str (not "int") to str

针对此问题，解决方法是：

主要是因为age的字段中使用int格式来验证，导致此问题。

age = input("age:")
