How to print zero-padded floating point numbers in python 2.6.1

Hello,

I thought that I could zero-pad a floating point number in 'print' by
inserting a zero after '%', but this does not work.

I get:

print '%2.2F' % 3.5
3.50
print '%02.2F' % 3.5
3.50

How can I get print (in a simple way) to print 03.50?

Best Regards,
Lorenzo

>>> print ("%.2f" % 3.5).zfill(5)
03.50
>>> print ("%5.2f" % 3.5).replace(' ','0')
03.50

Cheers,
Chris
