            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：

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')
