Python 文件写入和读取操作

python的文件写入和读取操作,是python自身携带的功能,不需要其他的import

简单的演示了写入和读取的操作

#!/usr/bin/env python
#!-*- coding=utf-8 -*-
#!Filename: using_file.py
__author__ = 'Durban Zhang'
poem = '''
Programming is fun When the work is done
if you wanna make your work also fun:
use Python!
'''
f = file('poem.txt','w')
f.write(poem)
f.close()
f = file('poem.txt')
while True:
    line = f.readline()
    if len(line) == 0:
        break;
    print line, #消除自动换行
f.close()

读取的操作中使用了,readline的函数,还有消除自动换行的特殊用法
