我正在尝试使用cx_Freeze编译Python3.3脚本。脚本使用win32com.client来控制。当我直接运行它时,这是完美的。但是当我编译它时,它会抛出这个异常。
Traceback (most recent call last):
File "O:\Python\3\lib\site-packages\cx_Freeze\initscripts\Console3.py", line 27, in <module>
exec(code, m.__dict__)
File "test.py", line 6, in <m
我有一个对象myobject,它可能返回None。如果返回None,则不会返回属性id
a = myobject.id
因此,当myobject为None时,上面的字符串会产生一个AttributeError
AttributeError: 'NoneType' object has no attribute 'id'
如果myobject为None,那么我希望a等于None。如何在一行语句中避免此异常,例如:
a = default(myobject.id, None)
我的main.py和spend.kv中有以下代码:

我有一些条件代码,看起来像这样:
if self.above and self.above.author and self.above.author.username!=self.author.username:
"notify above.author that someone has replied to their comment"
但是,如果没有self.above,或者其中一个评论没有作者,那么我会得到如下错误:
AttributeError: 'NoneType' object has no attribute 'author
import lxml.html
当我想要用cx_freeze编译时,给我一个错误:
Traceback (most recent call last):
File "C:\Python27\Scripts\cxfreeze", line 5, in <module>

File "C:\Python27\lib\site-packages\cx_Freeze\main.py", line 188, in main

在python中遇到此错误时遇到问题:
File "F:\dykrstra", line 36, in route
while node.label != node.prevNode.label:
AttributeError: 'NoneType' object has no attribute 'label'
在这个while循环中:
while node.label != node.prevNode.label:
node = node.prevNode
labels.append(node.label)

我试图使用Selenium登录到TradingView中,但似乎selenium无法找到密码字段并发送密钥,尽管我可以实时看到光标单击密码字段。我甚至尝试使用ActionChains发送密钥。我得到了以下错误:
AttributeError: 'NoneType' object has no attribute 'send_keys'
下面是我的密码。任何帮助都是非常感谢的!
