本文实例讲述了python实现查找系统盘中需要找的字符。分享给大家供大家参考。具体如下:
'''created on 2011-7-13@author: 123'''import os#保存当前有的磁盘def existdisk(): curdisks = [] alldisks = ['c:', 'd:', 'e:', 'f:', 'g:', 'h:', 'i:', 'j:', 'k:', \    'l:', 'm:', 'n:', 'o:', 'p:', 'q:', 'r:', 's:', 't:', \    'u:', 'v:', 'w:', 'x:', 'y:', 'z:', 'a:', 'b:'] for disk in alldisks:  if os.path.exists(disk):   curdisks.append(disk) return curdisks#目录中含有查找的字符def searchdirfile(path, src): if not os.path.exists(path):  print %s 路径不存在 % path for root , dirs, files in os.walk(path, true):  if - 1 != root.find(src):  #路径名中是否存在要查找的字符   print root   for item in files:    path = os.path.join(root, item)    if - 1 != path.find(src):    #文件列表中是否有要查找的字符    print path#查找文件内容中有要查找的字符def searchfile(path, src):  if not os.path.exists(path):  print %s 路径不存在 % path for root, dirs, files in os.walk(path, true):  for item in files:   path = os.path.join(root, item)   try:    f = open(path, 'r')    for eachline in f.readlines():     if - 1 != eachline.find(src):     #文本内容中是否有要查找的字符      print path      f.close()      break   except:    pass#查找当前所有磁盘目录下是否有要找的字符def searchalldirfile(src):  curdisks = existdisk() for disk in curdisks:  disk = disk + '\\'  searchdirfile(disk, src) print 完成搜索#查找当前所有磁盘目录文件内容下是否有要找的字符def searchallfile(src):    curdisks = existdisk() for disk in curdisks:  disk = disk + \\  searchfile(disk, src) print 完成搜索searchallfile('十进制转二进制')
希望本文所述对大家的python程序设计有所帮助。
