Re: Variable Assignment/Scope Question

Hi,

I have been struggling with no avail to archive assignment
of a
variable within a loop to be used later outside the loop,
i.e., the
following use of $ fails with undefined error:

<py:for each="i in range(my_range)">
  <py:with
var="variable=i"></py:with>
</py:for>

<py:if test="my_range &lt;= 1">
  <py:with
var="variable=0"></py:with>
</py:if>

<py:for each="v in range(variable)">
  <span>do something</span>
</py:for>

What is the trick there? Any hint would be greatly
appreciated!

Sincerely,
Jerry

Hi Chris,

That's also how I interpreted the documentation -- just
couldn't
convince myself that such deceptively naive functionality
does not
exist in Genshi -- without even a workaround/cheat?

Thanks.

Jerry

Hi Chris,

Stupid me, that's indeed very true -- maybe I was blinded by
my
reluctance to pass presentation centric variables to the
Genshi
template.

Thanks again.

Jerry
