合并（拼接）字符串 "+"

 

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：

first_name = "ada"
last_name = "lovelace"
full_name = first_name+" "+last_name
print("Hello,"+ full_name.title() + "!")   #full_name中的字符 首字母大写


执行结果为：

C:Users	byAppDataLocalProgramsPythonPython37python.exe C:/py3/rumen_shijian/hebing_+.py

Hello,Ada Lovelace!

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：

first_name = "ada"
last_name = "lovelace"
full_name = first_name+" "+last_name
message = "Hello,"+ full_name.title() + "!"
print(message)

执行结果为：

C:Users	byAppDataLocalProgramsPythonPython37python.exe C:/py3/rumen_shijian/hebing_+.py

Hello,Ada Lovelace!
