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,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。
