You can use something like this:
template file:
your template text  your template text %variable% your template text
%variable2%
%xxx% is the placeholder for "variable" xxx (you can replace % with what
you
like)
in your python code:
"""
import string
template = open("yourtemplatefile")
templateText = template.read()
template.close()
templateText = string.replace(templateText, "%variable%",
str(value_of_variable))
templateText = string.replace(templateText, "%variable2%",
str(value_of_variable2))
# an so on....
# printing a minimal http header
print "Content-type: text/html"
print
# printing the template filled with the variables
print templateText
# You can do it better using a value-filled dictionary:
val = {"variable":value1, "variable2":value2, } # etc.....
# you may read this dict from a shelv db for example...
for k in val.keys():
    templateText = string.replace(templateText, "%"+ k + "%", val[k] )
# printing a minimal http header
print "Content-type: text/html"
print
# printing the template filled with the variables
print templateText
# And you can use both the mothods at the same time...
# happy coding
