the*_*ech 5 html python ipython jupyter jupyter-notebook
我想将简单的变量传递给Jupyter上的html单元：
a=5
%%html
<html>
<head>
<script type="text/javascript">
window.alert(a);
</script>
</head>
</html>
这将返回错误：
Javascript error adding output!
ReferenceError: a is not defined
See your browser Javascript console for more details.
这是一个hacky解决方案：
a=5
html_code ="""
<html>
<head>
<script type="text/javascript">
window.alert(%s);
</script>
</head>
</html>""" % a
from IPython.display import HTML
HTML(html_code)
