def secsToHMS(seconds):
     """
     Convert seconds to hours:minutes:seconds, with seconds rounded 
to hundredths of a second
     """
     minutes, seconds = divmod(seconds, 60)
     hours, minutes = divmod(minutes, 60)
     return "%02d:%02d:%2.2f" % (hours, minutes, seconds)

print secsToHMS(87154.04987)  --> 24:12:34.05  (what I wanted)

print secsToHMS(154.04987) --> 00:02:34.05 (what I wanted)

but
print secsToHMS(4.04987) --> 00:00:4.05 (I wanted 00:00:04.05)

I don't see how to get 00:00:04.05  using %f . 
<http://www.python.org/doc/2.4.1/lib/typesseq-strings.html> is as clear as mud.
