python 合并字符串

[root@chenbj python]# cat name.py
#!/usr/bin/env python
# _*_ coding:utf-8 _*_

first_name = "chen"
last_name = "baojia"
full_name = first_name + " " + last_name
print(full_name)
[root@chenbj python]# python name.py
chen baojia

示例2

[root@chenbj python]# cat name.py
#!/usr/bin/env python
# _*_ coding:utf-8 _*_

first_name = "chen"
last_name = "baojia"
full_name = first_name + " " + last_name
print("Hello, " + full_name.title() + "!")
[root@chenbj python]# python name.py
Hello, Chen Baojia!

在这里，一个问候用户的句子中使用了全名，并使用了方法title() 来将姓名设置为合适的格式。这些代码显示一条格式良好的简单问候语:

[root@chenbj python]# cat name.py
#!/usr/bin/env python
# _*_ coding:utf-8 _*_

first_name = "chen"
last_name = "baojia"
full_name = first_name + " " + last_name
message = ("Hello, " + full_name.title() + "!")
print(message)
[root@chenbj python]# python name.py
Hello, Chen Baojia!

你可以使用拼接来创建消息，再把整条消息都存储在一个变量中:
