Python Split string in a certain length

Question

I have this situation: I got a string that I want to split every X characters. My problem is that the split method only splits the string based on a string such as:

a = 'asdeasxdasdqw'
print a.split('x')

>>>['asdeasx', 'dasdqw']

What I need is something similar to:

[pseudocode]

paragraph = 'my paragraph'

split_offset = 4
print paragraph.split(split_offset)

>>> ['my pa', 'ragraph']

Solution

This is called slicing:

>>> paragraph[:5], paragraph[5:]
('my pa', 'ragraph')

To answer the "split every X characters" question, you would need a loop:

>>> x = 5
>>> [paragraph[i: i + x] for i in range(0, len(paragraph), x)]
['my pa', 'ragra', 'ph']

There are more solutions to this though, see:

• Split python string every nth character?
• What is the most "pythonic" way to iterate over a list in chunks?
