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'''
或
"""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:~$
