Example 1: split string by length python
>>> x = "qwertyui"
>>> chunks, chunk_size = len(x), len(x)/4
>>> [ x[i:i+chunk_size] for i in range(0, chunks, chunk_size) ]

# strings are immutable in Python,
# we have to create a new string which
# includes the value at the desired index
s = s[:index] + newstring + s[index + 1:]
