AFAIK, earlier versions of python does not have a function/module that
converts a number to its binary representation; so you might have to
build your own function there.
The concept of base-2 conversion is simple, the modulus for powers of 2.
>>> def bin(n):
... if n == 0: return '0'
... if n == 1: return '1'
... return mybin(n // 2) + str(n % 2)
(that function is simple, but might be slow if you had to concatenate
large strings)
or generally:
def rebase(n, base=2):
'''
Convert a positive integer to number string with base `base`
'''
if 0 <= n < base: return str(n)
return rebase(n // base, base) + str(n % base)
than you simply map your string to ord and the bin function, ''.join,
and done.
