just got an interesting idea for the core of the converter,
maybe you like it:
def int_to_bin(v):
i=1
d=1
a=0
while i<v:
if i & v:
a+=d
i<<=1 # could also be i*=2
d*=10
return a
>>> int_to_bin(5)
101
>>> print "%08d" % int_to_bin(5)
00000101
I think the formatting bit is a tad nicer then '0' * (8-len(...)))
Cheers
