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。
