python多行注释和跨行字符串

1》单行注释:#      如:

#hello python

2》多行注释:三个单引号(或三个双引号),如:

”’hello python

hello world”’

“””hello python

hello world”””

3》三个单引号(或三个双引号)也可以表示跨行字符串,如:

>>> s=”’

… hello

… python

… ”’

>>> s

‘\nhello\npython\n’

>>> print s

hello

python

>>> 

4》跨行字符串可以用来进行格式化输出,下面是一个使用跨行字符串进行格式化输出的例子:

song@ubuntu:~$ vi ex2.py
song@ubuntu:~$ more ex2.py
#!/usr/bin/env python
#_*_ coding:utf-8 _*_
name=raw_input(‘Please input your name:’)
age=raw_input(‘Please input your age:’)
job=raw_input(‘Please input your job:’)
sex=raw_input(‘Please input your sex:’)
print ”’Personnal information of %s:
name:%s
age:%s
job:%s
sex:%s
”’ % (name,name,age,job,sex)

song@ubuntu:~$ python ex2.py
Please input your name:python
Please input your age:18
Please input your job:IT
Please input your sex:m  
Personnal information of python:
name:python
age:18
job:IT
sex:m

song@ubuntu:~$
