Question

Let’s say I’d like to split some data into 60-character parts and store them in a hash. I’ve got the following solution, but it seems a bit dirty to me: (because of iteration and constant reassigning)

i = 0
while signature != '':
   header_hash['Some-Authorization-' + i] = signature[:60]
   signature = signature[60:]
   i += 1

Can you come up with a better way of handling this?

Answer 1

Although fairly similar to how to evenly split a list into chunks I believe this to still be a valid problem, but will contain part of the answer to that previous question:

def hashing(header_hash, signature, hash_size):
     for index, i in enumerate(xrange(len(signature), hash_size)):
          header_hash['Some-Authorization-%s' % index] = signature[i:i+hash_size]

This would be my answer, Looking over the itertools functions provided I suspect rejoining them after the grouping would negate any benefit from using itertools.
