like this one ?

b = dict(name="Sue", job="SAS sharp-shooter")
print "$b['name']$ works as b['job']"

Is it really easier to read that the following ?
"{0} works as {1}".format(b['name'],b['job'])

In the case in which b is an object having "job" and "name" attribute, 
the dynamic string will write

"$b.name$ works as $b.job$"
instead of
"{0}.name works as {0}.job".format(b)
