But where is the %b in Python?

Python doesn't have that. You can convert the number to a hex, and then
map the hex digitds to binary strings using a dictionary, like this:

Good idea, but shorter with -> http://cheeseshop.python.org/pypi/SE/2.2%20beta

>>> import SE
>>> Int_To_Binary = SE.SE (SE.SE ('0=0000 1=0001 2=0010 3=0011 4=0100 5=0101 6=0110 7=0111 8=1000 9=1001 A=1010 a=1010 B=1011 b=1011 C=1100 c=1100 D=1101 d=1101 E=1110 e=1110 F=1111 f=1111')
>>> Int_To_Binary ('%x' % 1234567890')
'01001001100101100000001011010010'

>>> Int_To_Binary.save ('se_definition_files/int_to_binary.se')

>>> SE.SE ('se_definition_files/int_to_binary.se') ('%X' % 987654321)
'00111010110111100110100010110001'
