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。
