[Tutor] to/from binary to/from integer (i.e.'01010101' =85)

[kiran at mhowlinux.org]

for any positive (int) to binary

a simple function would do the job

import math
def i2b(s):
   #check how many bits are required to represent the integer in binary
    i=int(math.log(s)/math.log(2))+1
    return ''.join([str((s&(2**(i-j-1)))>>(i-j-1)) for j in range(i)])
