Split string into groups of 3 characters

Question

I have a string

ddffjh3gs

I want to convert it into a list

["ddf", "fjh", "3gs"]

In groups of 3 characters as seen above. What is the best way to do this in python 2.7?

In the original string, `f` appears once. But in a list, there are two. Why? — falsetru, May 15 '17 at 15:11

Using list comprehension with string slice:

>>> s = 'ddffjh3gs'
>>> [s[i:i+3] for i in range(0, len(s), 3)]
['ddf', 'fjh', '3gs']
