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')

希望本文所述对大家的Python程序设计有所帮助。
