Split string into strings by length?

Question

Is there a way to take a string that is 4*x characters long, and cut it into 4 strings, each x characters long, without knowing the length of the s

Answer 1

Got an re trick:

In [28]: import re

In [29]: x = "qwertyui"

In [30]: [x for x in re.split(r'(\w{2})', x) if x]
Out[30]: ['qw', 'er', 'ty', 'ui']

Then be a func, it might looks like:

def split(string, split_len):
    # Regex: `r'.{1}'` for example works for all characters
    regex = r'(.{%s})' % split_len
    return [x for x in re.split(regex, string) if x]
