我收到此错误:“ImportError:无法导入名称 python”我该如何修复它?
File "G:\Python25\Lib\site-packages\PyAMF-0.6b2-py2.5-win32.egg\pyamf\util\__init__.py", line 15, in <module>
ImportError: cannot import name python
我该如何修复它? 如果您需要任何信息来了解如何解决此问题,我可以解释,只需询问即可。

How do I fix it?
If you need any info to know how to fix this problem, I can explain, just ask.
Thanks

您需要发布完整的回溯。您在这里显示的内容并不是那么有用。我最终挖掘出了 pyamf/util/init.py 的第 15 行。您应该发布的代码是
除非您的本地环境混乱,否则这应该不会失败。
您可以在交互式 Python shell 中“导入 pyamf.util”和“导入 pyamf.python”吗?如果您在 /tmp 中启动 Python 会怎么样(假设您在当前目录中可能有一个名为“pyamf.py”的文件。这是一件坏事。)

解决您的问题。我什至不知道 util/__init__.py 的第 15 行应该在哪里。因为我不明白,所以无法回答你的问题。相反,我将指出改进您的问题和代码的方法。
首先,正确使用标记语言,使所有代码都在一个代码块中。确保您已为代码命名,以便我们知道它来自 util/__init__.py 而不是某个随机文件。
在错误消息中,包含完整回溯,而不是最后两行。
在“if(not service_func):”等内容中停止使用括号,并使用空格代替,因此它是“if not service_func:”。 PEP 8 对此进行了讨论。
阅读 Python 文档并了解如何使用该语言。像“func_name = paths[len(paths) - 1]”这样的东西应该是“func_name = paths[-1]”
了解导入 函数,并且在这种情况下不要使用“exec”。你也不需要“exec allocate_string”——只需执行“self.addService(service_func, target)”
You need to post your full traceback. What you show here isn't all that useful. I ended up digging up line 15 of pyamf/util/init.py. The code you should have posted is
This should not fail unless your local environment is messed up.
Can you 'import pyamf.util' and 'import pyamf.python' in a interactive Python shell? What about if you start Python while in /tmp (on the assumption that you might have a file named 'pyamf.py' in the current directory. Which is a bad thing.)

Fix your question. I can't even tell where line 15 of util/__init__.py is supposed to be. Since I can't figure that out, I can't answer your question. Instead, I'll point out ways to improve your question and code.
First, use the markup language correctly, so that all the code is in a code block. Make sure you've titled the code, so we know it's from util/__init__.py and not some random file.
In your error message, include the full traceback, and not the last two lines.
Stop using parens in things like "if(not service_func):" and use a space instead, so its " if not service_func:". This is discussed in PEP 8.
Read the Python documentation and learn how to use the language. Something like "func_name = paths[len(paths) - 1]" should be "func_name = paths[-1]"
Learn about the import function and don't use "exec" for this case. Nor do you need the "exec assign_string" -- just do the "self.addService(service_func, target)"
