小编Joh*_*itt的帖子

I'm trying to understand one of the answers to this question:

Cannot pass an argument to python with "#!/usr/bin/env python"

#!/bin/sh
''''exec python -u -- "$0" ${1+"$@"} # '''

This works well, but I do not understand why it works with four ticks at the beginning of that line rather than three.

In addition, why the hash near the end of that string?

是否可以编写一个Jupyter笔记本,以便参数可以通过笔记本的URL传入？

例如,对于这样的URL:

http://jupyter.example.com/user/me/notebooks/notebook1.ipynb?Variable1=Value1&Variable2=Value2

如何可以访问Variable1,并Variable2在Jupyter细胞内？

据我所知,从这个github页面,我可以将.ipynb推送到我的仓库,然后直接从github运行我的笔记本.

当我让我的Jupyter将我的笔记本下载为.ipynb时,我得到了一个.ipynb.json.

我必须对该文件做什么才能让github为我打开带有nbviewer的笔记本？

据我了解,我应该能够foo在下面的代码段中打印变量.

from IPython.display import HTML
HTML('''
    <script type="text/javascript">
        IPython.notebook.kernel.execute("foo=97")
    </script>
     ''')
print(foo)

相反,我看到此错误消息:

NameErrorTraceback (most recent call last)
<ipython-input-2-91b73ee49ec6> in <module>()
      5     </script>
      6      ''')
----> 7 print(foo)

NameError: name 'foo' is not defined

我正在尝试使用这个答案,但努力使其成功.

FWIW,这是在Fedora 23上运行的最新Jupyter代码(根据pip).使这项工作的先决条件是什么？

$ cat foo.libsonnet
{
    local foo = 99,
    bar: [ foo, 101 ]
}
$ cat baz.jsonnet
{
    local foo = import 'foo.libsonnet',
    baz: [foo.foo, foo.bar]
}
$ jsonnet baz.jsonnet
RUNTIME ERROR: field does not exist: foo
        baz.jsonnet:3:11-18     thunk <array_element>
        baz.jsonnet:3:10-28     object <anonymous>
        During manifestation

在这个例子中，很容易访问bar的字段foo。有什么办法可以baz.jsonnet访问当地人吗foo.libsonnet？

如果答案是否定的，我应该如何实现foo，baz以便我可以访问in Both和 also in 的foo字段？foo.libsonnetfoo.libsonnetbaz.jsonnet
