If you are dealing with a form then you could just direct the 'action' to 
point to the 'vacinateplan' script, then use REQUEST['animal'] or 

Alternatively... if u restructure your URLs so that they look like:

www.xyz.com/vacinateplan/hippo  or
www.xyz.com/vacinateplan/giraffe  etc

Then you can set up your python script ("vacinateplan") to access the 
'animal' variable as follows:

print traverse_subpath[0]

It is also possible that i am unclear on your use case!
