Is there a way make fixed width substitutions with the python String.Template objects substitution language

For example if I wanted s to be 'A string 0003' how would I modify this code:

from string import Template
stmpl=Template("A string ${tcount}")
s=stmpl.substitute(tcount=3)
print(s)

read throu PEP 292 , "Simpler String Substitutions" does not make it as expressive as % format. i think you had to format the substitution yourself before feed to the template. something like 

"{0:05}".format(3)
