在Python搜索中跳過目錄

Question

我正在運行以下代碼，並且我想跳過3個文件夾，其名稱分別爲： folder1，folder2，.repository。

但是，如果某些文件夾不存在，我得到的錯誤：

indentationerror：取消縮進不匹配任何外部縮進級別

如何搜索跳過的文件夾，即使他們不目前沒有得到任何錯誤？在這裏我的代碼：

import re 
import os 
from os.path import join 
comment=re.compile(r"<!--\s+\| Start of user code \(user defined modules\)\s+\|-->\s+<!--\s+\| End of user code\s+\|-->", re.MULTILINE) 
tag="<module>" 

for root, dirs, files in os.walk("."): 
    dirs.remove("folder1") 
    dirs.remove("folder2") 
    dirs.remove(".repo") 
    if "pom.xml" in files: 
     p=join(root, "pom.xml") 
     print("Checking",p) 
     with open(p) as f: 
      s=f.read() 
     if tag in s and comment.search(s): 
      print("The following file has been modified",p) 

------ UPDATE：

import re 
import os 
from os.path import join 
comment=re.compile(r"<!--\s+\| Start of user code \(user defined modules\)\s+\|-->\s+<!--\s+\| End of user code\s+\|-->", re.MULTILINE) 
tag="<module>" 

for root, dirs, files in os.walk("/home/temp/"): 
dirs.remove("/home/temp/test1") 
dirs.remove("/home/temp/test2") 
dirs.remove("/home/temp/test3") 

     if "pom.xml" in files: 
     p=join(root, "pom.xml") 
     print("Checking",p) 
     with open(p) as f: 
      s=f.read() 
     if tag in s and comment.search(s): 
      print("The following file contains user code modules:-------------> ",p) 

這裏輸出：

python /home/temp/test_folder/python_script_4.py 
    File "/home/temp/test_folder/python_script_4.py", line 12 
    if "pom.xml" in files: 
    ^
IndentationError: unexpected indent 

最後更新--------->

import re 
import os 
from os.path import join 
comment=re.compile(r"<!--\s+\| Start of user code \(user defined modules\)\s+\|-->\s+<!--\s+\| End of user code\s+\|-->", re.MULTILINE) 
tag="<module>" 

for root, dirs, files in os.walk("/home/dlopez/temp/test_folder/"): 
dirs.remove("/home/temp/test_folder/test1") 
dirs.remove("/home/temp/test_folder/test2") 
dirs.remove("/home/temp/test_folder/test3") 

if "pom.xml" in files: 
    p=join(root, "pom.xml") 
    print("Checking",p) 
    with open(p) as f: 
     s=f.read() 
     if tag in s and comment.search(s): 
      print("The following file contains user code modules:-------------> ",p) 

而且我的輸出：

python /home/temp/test_folder/python_script_5.py 
Traceback (most recent call last): 
    File "/home/dlopez/temp/test_folder/python_script_5.py", line 8, in <module> 
    dirs.remove("/home/temp/test_folder/test1") 
ValueError: list.remove(x): x not in list 

請幫助謝謝！ :)

你的，如果不符合當前的縮進

import re 
import os 
from os.path import join 
comment=re.compile(r"<!--\s+\| Start of user code \(user defined modules\)\s+\|-->\s+<!--\s+\| End of user code\s+\|-->", re.MULTILINE) 
tag="<module>" 

for root, dirs, files in os.walk("/home/dlopez/temp/"): 
dirs.remove("/home/dlopez/temp/test1") 
dirs.remove("/home/dlopez/temp/test2") 
dirs.remove("/home/dlopez/temp/test3") 

     if "pom.xml" in files: # The if statement is not aligned to anything 
     p=join(root, "pom.xml") 
     print("Checking",p) 
     with open(p) as f: 
      s=f.read() 
     if tag in s and comment.search(s): 
      print("The following file contains user code modules:-------------> ",p) 

改變它的縮進：

import re 
import os 
from os.path import join 
comment=re.compile(r"<!--\s+\| Start of user code \(user defined modules\)\s+\|-->\s+<!--\s+\| End of user code\s+\|-->", re.MULTILINE) 
tag="<module>" 

for root, dirs, files in os.walk("/home/dlopez/temp/"): 
    # Skip the dirs you want looping a list 
    for skipped in ("/home/dlopez/temp/test1", "/home/dlopez/temp/test1", "/home/dlopez/temp/test3"): 
     if skipped in dirs: dirs.remove(skipped) 

    if "pom.xml" in files: 
     p=join(root, "pom.xml") 
     print("Checking",p) 
     with open(p) as f: 
      s=f.read() 
      if tag in s and comment.search(s): 
       print("The following file contains user code modules:-------------> ",p)
