I was hoping there would be something to continue the existing patterns 
like;
hex(value)
oct(value)
bin(value)

or perhaps

print "%d" % value  #Decimal
print "%x" % value  #Hex
print "%o" % value  #Octal
print "%b" % value  #Binary

I ended up finding the baseconvert module in the CookBook as well and 
changing it to default to decimal->binary.

def baseconvert(number, fromdigits=BASE10, todigits=BASE2):

properly).
