Well, I'm not familiar with Perl, but perhaps this will help you?

>>> mydict = { 'name': 'Jeff', 'food': 'Spam' }
>>> template = 'Hi, my name is %(name)s, and my favorite food is 
%(food)s!'
>>> print template % mydict
Hi, my name is Jeff, and my favorite food is Spam!
>>> 

Your template contains '%(var)s' as placeholders.  When you 
provide the string formatting operator (%) with a dictionary, it 
will then go through your template and substitute every '%(var)s' 
with the value of mydict[var].
