python - How to import modules into web.py templates? -

i have following piece of code:

render = web.template.render('templates/') app = web.application(urls, globals()) 

i read template imports in web.py cookbook.

now, when try import re in template:

render = web.template.render('templates/', globals={'re':re}) app = web.application(urls, globals()) 

i got error:

<type 'exceptions.typeerror'> @ /'dict' object not callable 

and line showed in traceback: app = web.application(urls, globals()).

but when modify it:

app = web.application(urls) 

the error gone, , re imported in template.

i don't understand how globals={'re': re} in web.template.render breaks it?

why can't keep both globals in second example?

i'm guessing there else doing in script or template causing error. if showed complete example, easier see. here working example:

import web import re  urls = ('/', 'index') render = web.template.render('templates/', globals={'re':re}) app = web.application(urls, globals())  class index:     def get(self):         args = web.input(s='')         return render.index(args.s)  if __name__ == '__main__':     app.run() 

and template, index.html:

$def with(s)  $code:     if re.match('\d+', s):         num = 'yes'     else:         num = 'no'  <h1>is arg "$:s" number? $num!</h1>
