Passing JavaScript variable to Python

Question

For example:

#!/usr/bin/python
print "This is python."

print "<script type="text/javascript">
          var pass_to_python = new Number(7)
       </script>"

the_number = pass_to_python???

How do I get the pass_to_python in python?

Answer 1

With pyv8 you can execute javascript from within Python.

import PyV8

class Global(PyV8.JSClass):
    pass

with PyV8.JSContext(Global()) as ctxt:
    the_number = ctxt.eval("var pass_to_python = new Number(7)")
