python文件学习

f=open(‘test‘.txt‘,‘w‘)//写入文件

f=open(‘test.txt‘,‘a‘)//追加写入文件

read()一次性读取

readline()读取一行

readlines()读取一行，并保留为一个list里面

seek(0)文件指针指向开头

tell()显示目前指针位置

os和stat模块获取文件：

stat：

import os

import stat

fileStats = os.stat ( ‘test.txt‘ )

fileMode = fileStats [ stat.ST_MODE ]

if stat.S_ISREG ( fileStats [ stat.ST_MODE ] ):

print ‘Regular file.‘

elif stat.S_ISDIR ( fileStats [ stat.ST_MODE ] ):

print ‘Directory.‘

elif stat.S_ISLNK ( fileStats [ stat.ST_MODE ] ):

print ‘Shortcut.‘

elif stat.S_ISSOCK ( fileStats [ stat.ST_MODE ] ):

print ‘Socket.‘

elif stat.S_ISFIFO ( fileStats [ stat.ST_MODE ] ):

print ‘Named pipe.‘

elif stat.S_ISBLK ( fileStats [ stat.ST_MODE ] ):

print ‘Block special device.‘

elif stat.S_ISCHR ( fileStats [ stat.ST_MODE ] ):

print ‘Character special device.‘

os.path:

fileStats = ‘test.txt‘

if os.path.isdir ( fileStats ):

print ‘Directory.‘

elif os.path.isfile ( fileStats ):

print ‘File.‘

elif os.path.islink ( fileStats ):

print ‘Shortcut.‘

elif os.path.ismount ( fileStats ):

print ‘Mount point.‘
