    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:~$
