1、"+"的用法：
1 #!/usr/bin/env python 2 # -*- coding:utf-8 -*- 3 first_name = "ada" 4 last_name = "lovelace" 5 full_name = first_name+" "+last_name 6 print(full_name) 7 8 执行结果为： 9 C:Users byAppDataLocalProgramsPythonPython37python.exe C:/py3/rumen_shijian/hebing_+.py
10 ada lovelace 11 12 进程已结束,退出代码0
2、"+"和.title()的用法：
1 first_name = "ada" 2 last_name = "lovelace" 3 full_name = first_name+" "+last_name 4 print("Hello,"+ full_name.title() + "!") #full_name中的字符 首字母大写 5 6 7 执行结果为： 8 9 C:Users byAppDataLocalProgramsPythonPython37python.exe C:/py3/rumen_shijian/hebing_+.py
10 Hello,Ada Lovelace! 11 12 进程已结束,退出代码0
3、使用拼接来创建消息，再把整条消息都储存在一个变量中：
1 first_name = "ada" 2 last_name = "lovelace" 3 full_name = first_name+" "+last_name 4 message = "Hello,"+ full_name.title() + "!" 5 print(message) 6 7 执行结果为： 8 9 C:Users byAppDataLocalProgramsPythonPython37python.exe C:/py3/rumen_shijian/hebing_+.py
10 Hello,Ada Lovelace! 11 12 进程已结束,退出代码0
