實現類概念並不在Python工作

Question

計劃1：基於功能： -

import xml.etree.ElementTree as ET 
import sys 
doc  = ET.parse("users.xml") 
root  = doc.getroot() 
root_new = ET.Element("users") 
for child in root: 
    username    = child.attrib['username'] 
    password    = child.attrib['password'] 
    # create "user" here 
    user = ET.SubElement(root_new, "user") 
    user.set("username",username)    
    user.set("password",password) 
    #checking attribute for skipping KeyError 
    if 'remote_access' in child.attrib: 
     remote_access = child.attrib['remote_access'] 
     user.set("remote_access",remote_access) 
    for g in child.findall("group"): 
     # create "group" here 
     group  = ET.SubElement(user,"group") 
     if g.text != "lion": 
      group.text = g.text 
tree = ET.ElementTree(root_new) 
tree.write(sys.stdout) 

這是XML： -

<users> 
<user username="admin" password="admin" remote_access="yes"></user> 
<user username="private_user1" password="user1" ><group>group1</group><group>group2</group></user> 
<user username="private_user2" fullname="user2" password="user2"><group>group1</group><group>group2</group></user> 
</users> 

我的課implementaion： - 完全錯誤的:(

import xml.etree.ElementTree as ET 
import sys 

class users_detail (object): 

    def __init__(self, xml_path): 
    """bla bla 
    """ 
    try: 
     doc = ET.parse("users.xml") 
    except: 
     print 'xml not found' 
     root  = doc.getroot() 
     root_new = ET.Element("users") 
     for child in root: 
      username    = child.attrib['username'] 
      password    = child.attrib['password'] 
      user = ET.SubElement(root_new, "user") 
      user.set("username",username)    
      user.set("password",password) 
      if 'remote_access' in child.attrib: 
       remote_access = child.attrib['remote_access'] 
      for g in child.findall("group"): 
       group  = ET.SubElement(user,"group") 
       if g.text != "lion": 
        group.text = g.text 
     tree = ET.ElementTree(root_new) 
     tree.write(sys.stdout) 
if __name__=='main': 
    users_detail() 

如何通過面向對象的概念類以更好的方式實現這個，而我的類實現根本不起作用。阿斯幫助我。 :(

我需要上面的代碼轉換爲Python類：多數民衆贊成在需求量的:(

（該print語句縮進一級後太遠一切）你有一個壓痕問題

。從我這裏告訴你的老師，把隨機代碼改寫成一個「類」是無稽之談。對於這樣的代碼，在Python中不需要類。
