- 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。
