[英]Python - match directories with pattern (regular expression)
我寫了一個循環,忽略了其中包含.txt文件的所有子目錄。
src = raw_input("Enter source disk location: ")
src = os.path.abspath(src)
dst = raw_input("Enter first destination to copy: ")
dst = os.path.abspath(dst)
dest = raw_input("Enter second destination to move : ")
dest = os.path.abspath(dest)
path_patter = '(\S+)_(\d+)_(\d+)_(\d+)__(\d+)_(\d+)_(\d+)'
for dir, dirs, files in os.walk(src):
if any(f.endswith('.txt') for f in files):
dirs[:] = [] # do not recurse into subdirectories
continue
files = [os.path.join(dir, f) for f in files ]
for f in files:
part1 = os.path.dirname(f)
part2 = os.path.dirname(os.path.dirname(part1))
part3 = os.path.split(part1)[1]
path_miss1 = os.path.join(dst, "missing_txt")
path_miss = os.path.join(path_miss1, part3)
path_missing = os.path.join(dest, "missing_txt")
searchFileName = re.search(path_patter, part3)#### update
if searchFileName:#####update
try:
if not os.path.exists(path_miss):
os.makedirs(path_miss)
else:
pass
if os.path.exists(path_miss):
distutils.dir_util.copy_tree(part1, path_miss)
else:
debug_status += "missing_file\n"
pass
if (get_size(path_miss)) == 0:
os.rmdir(path_miss)
else:
pass
if not os.path.exists(path_missing):
os.makedirs(path_missing)
else:
pass
if os.path.exists(path_missing):
shutil.move(part1, path_missing)
else:
pass
if (get_size(path_missing)) == 0:
os.rmdir(path_missing)
else:
pass
except Exception:
pass
else:
continue
在這種情況下,如何修改此代碼以將目錄名與正則表達式進行比較。 (它必須忽略帶有.txt文件的目錄)
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))
我在這里做了幾件事,希望這個例子對您有所幫助
