在本例中,如何修改此代码以将目录名与正则表达式进行比较。(它必须忽略包含.txt文件的目录)
我在这里做了几件事,希望这个例子能有所帮助
- 我为WindowsFS编写了这篇文章,因此使用了两个路径转换函数
- 此脚本会忽略带有.txt文件的dirs,就像您实现它一样
- 此脚本将从启动脚本的目录开始,并且仅在模式匹配时打印文件名。对于上一条规则未忽略的所有子目录,都会执行此操作
- 在python中使用正则表达式,并使其针对每个目录再次编译,因此您会得到:'directory/(\S+)(\d+)(\d+)\uuud+)(\d+)(\d+)'
import os
import re
def createEscapedPattern(path,pattern):
newPath = os.path.normpath(path)
newPath = newPath.replace("\\","\\\\\\\\")
return newPath + "\\\\\\\\" + pattern
def createEscapedPath(path):
newPath = os.path.normpath(path)
return newPath.replace("\\","\\\\")
src = 'C:\\Home\\test'
path_patter = '(\S+)_(\d+)_(\d+)_(\d+)__(\d+)_(\d+)_(\d+)$'
p = re.compile(createEscapedPattern(src,path_patter))
for dir, dirs, files in os.walk(src):
if any(f.endswith('.txt') for f in files):
dirs[:] = []
continue
if any(p.match(createEscapedPath(dir)) for f in files):
for f in files:
print createEscapedPath(dir + "/" + f)
p = re.compile(createEscapedPattern(dir,path_patter))
