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

[Lorenzo Di Gregorio]

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 '%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?

print '%05.2F' % 3.5

The size codes are not <pre>.<post>... They are
<min-width>.<post>...

So above you've specified a zero-filled field of width 2, of which 2
of them come after the decimal point (leaving the decimal point and
anything in front of it as "oversized" data.

To get two digits in front, and two behind, you need to specify 5.2;
and from that, using a leading 0 should do zero-fill when the data is
less than that width.
