Thanks very much, Brian. Here's what I have now, and it works.
==============================
# formatDemo.py
while True:
print "enter a float, 'q' to quit, or nothing to accept default
float of 1234.56789"
x = raw_input()
if x == "":
print "x will be the default 1234.56789"
x = 1234.56789
elif x in "qQ":
break
else:
x = float(x)
floatFormatString = raw_input("enter a float format string such as
'.4f' or '.3e': ")
printValue = ('%' + floatFormatString ) %x
print "%f formatted with '%s' is %s" %(x, floatFormatString, printValue)
print
======================================
