CherryPy vs Django,你会使用它,为什么？

我可以通过哪种方式判断电脑是否配有wifi适配器？
当我测试我的代码时,它有效,但我不确定,它会一直有效吗？

private bool hasWifi()
{
    try
    {
        WlanClient wlanclient = new WlanClient();
    }
    catch (System.ComponentModel.Win32Exception except)
    {
        return false;
    }

    return true;
}

嗨,我是用瓶和SQLAlchemy的,我试图让球队的比赛关系到让所有的比赛是否是TEAM1或TEAM2(所以我想要的是能够通过获得所有比赛的球队给出匹配属性,无论它是否TEAM1或TEAM2在Match表),我得到的错误:

sqlalchemy.exc.AmbiguousForeignKeysError:无法确定关系Team.matches上父/子表之间的连接条件

链接表的链接路径有多个.指定foreign_keys参数,提供应列为包含对父表的外键引用的列的列表.

class Match(db.Model):
  id = db.Column(db.Integer, primary_key=True)
  map = db.Column(db.String(80), index=True)
  date = db.Column(db.DateTime, index=True)
  agreed = db.Column(db.Boolean)
  done = db.Column(db.Boolean)
  ladder_id = db.Column(db.Integer, db.ForeignKey('ladder.id'))
  team1_id = db.Column(db.Integer, db.ForeignKey('team.id'))
  team2_id = db.Column(db.Integer, db.ForeignKey('team.id'))
  team1_rounds = db.Column(db.Integer)
  team2_rounds = db.Column(db.Integer)
  team1_accepted_score = db.Column(db.Boolean)
  team2_accepted_score = db.Column(db.Boolean)
  points = db.Column(db.Integer)

  team1 = db.relationship('Team', foreign_keys='Match.team1_id')
  team2 = db.relationship('Team', foreign_keys='Match.team2_id')

class Team(db.Model):
  id = db.Column(db.Integer, primary_key=True)
  name = db.Column(db.String(80), index=True) …

我想用以下代码将docx文件转换为pdf

import sys
import os
import comtypes.client


wdFormatPDF = 17

in_file = os.path.abspath(sys.argv[1])
out_file = os.path.abspath(sys.argv[2])

word = comtypes.client.CreateObject('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()

这是一个错误

ImportError: cannot import name COMError

我已经安装了comtypes包.

我是python的新手,我无法弄清楚如何解决这个问题.

堆栈跟踪

Traceback (most recent call last):

Odoo模块总是有两个文件__init__.py和__openerp__.py.

dhl_module
          |-- controller
          |-- models
          |-- views
          |-- __init__.py
          |-- __openerp__.py

该文件__openerp__.py包含一个dict而不将其分配给名称.该dict存储有关模块的信息.它看起来像这样:

# -*- coding: utf-8 -*-
