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。
