blocks|key|1579551|text|问题是python-code不是标识符。解析器将其视为python减去code。当然，这并不能满足您的要求。您需要使用同时也是有效python标识符的文件名。尝试将-替换为下划线。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1579552|entityMap^0|3|B|R|6|Z|4|2A|1|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

The problem is that <code>python-code</code> is not an identifier. The parser sees this as <code>python</code> minus <code>code</code>. Of course this won't do what you're asking. You will need to use a filename that is also a valid python identifier. Try replacing the <code>-</code> with an underscore.

blocks|key|1579598|text|您可能可以通过某种__import__+hack来导入它，但是如果您还不知道如何使用它，那么就不应该这样做。Python模块名称应该是有效的变量名(“标识符”)+--这意味着如果您有一个模块foo_bar，那么您可以在Python+(print+foo_bar)中使用它。您无法使用奇怪的名称(print+foo-bar+->语法错误)做到这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1579599|entityMap^0|9|A|2N|7|39|D|43|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

You could probably import it through some <code>__import__</code> hack, but if you don't already know how, you shouldn't. Python module names should be valid variable names ("identifiers") -- that means if you have a module <code>foo_bar</code>, you can use it from within Python (<code>print foo_bar</code>). You wouldn't be able to do so with a weird name (<code>print foo-bar</code> -> syntax error).

blocks|key|1364545|text|在代码中需要注意的另一件事是，import不是一个函数。因此，import(python-code)应该是import+python-code，正如一些人已经提到的，它被解释为“导入python减去代码”，而不是您想要的。如果确实需要导入名称中带有破折号的文件，可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1364546|python_code+=+__import__('python-code')|code-block|syntax|javascript|1364547|但是，正如上面提到的，这并不是真正推荐的。如果文件名是由您控制的，则应该更改文件名。|1364548|entityMap^0|V|J|1H|I|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

One other thing to note in your code is that import is not a function. So <code>import(python-code)</code> should be <code>import python-code</code> which, as some have already mentioned, is interpreted as "import python minus code", not what you intended. If you really need to import a file with a dash in its name, you can do the following::

<pre><code>python_code = __import__('python-code')
</code></pre>

But, as also mentioned above, this is not really recommended. You should change the filename if it's something you control.

blocks|key|1364649|text|虽然正确的文件命名是最好的方法，但如果python-code不在我们的控制之下，使用__import__进行黑客攻击要比复制、重命名或以其他方式扰乱其他作者的代码要好。但是，我尝试过，除非我重命名该文件并添加.py扩展名，否则它不起作用。在研究了如何获取.py的描述的the+doc之后，我得到了以下结论：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1364650|import+imp

Although proper file naming is the best course, if <code>python-code</code> is not under our control, a hack using <code>__import__</code> is better than copying, renaming, or otherwise messing around with other authors' code. However, I tried and it didn't work unless I renamed the file adding the <code>.py</code> extension. After looking at <a href="https://docs.python.org/2/library/imp.html" rel="nofollow noreferrer">the doc</a> to derive how to get a description for <code>.py</code>, I ended up with this:


<pre><code>import imp

try:
 python_code_file = open("python-code")
 python_code = imp.load_module('python_code', python_code_file, './python-code', ('.py', 'U', 1))
finally:
 python_code_file.close()
</code></pre>

It created a new file <code>python-codec</code> on the first run.

On Python 3 use <a href="https://docs.python.org/3.7/library/importlib.html#importlib.import_module" rel="noreferrer">import_module</a>:

<pre><code>from importlib import import_module
python_code = import_module('python-code')
</code></pre>

More generally,

<pre><code>import_module('package.subpackage.module')
</code></pre>

Basically when I have a python file like:

<pre><code>python-code.py
</code></pre>

and use:

<pre><code>import (python-code)
</code></pre>

the interpreter gives me syntax error.

Any ideas on how to fix it? Are dashes illegal in python file names?

Is it ok to use dashes in Python files when trying to import them?

解释器

Python

基本上，当我有一个python文件时：python-code.py并使用：import (python-code)解释器给了我语法错误。对如何修复它有什么想法吗？python文件名中的破折号是非法的吗？
