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。
