How can I split a string in Python?

Question

Possible Duplicates:
Split python string every nth character?
What is the most “pythonic” way to iterate over a list in chunks?

I need to split a string into equal parts. For example, if I have this string:

string = "123456781234567812345678"

I need to cut every 8 characters:

["12345678", "12345678", "12345678"]

nice find, himanshu! makes me feel good about my own answer, since it's exactly the same. haha. — Sean Johnson, Sep 08 '12 at 04:57
@SeanJohnson Hardly, the other answer isn't nearly as enthusiastic! — Tim Post, Sep 08 '12 at 04:59

This is actually a great application for a python list comprehension one-liner!

my_str="123456781234567812345678"
splits=[my_str[x:x+8] for x in range(0,len(my_str),8)]
//splits = ["12345678","12345678","12345678"]

Let me know if you have any questions.

I'd rename `str`. It's conflicting with the built-in type `str`. – Blender Sep 08 '12 at 05:01
That second answer from the linked question is pretty neat: `map(''.join, zip(*[iter(my_str)] * 8))`. – Blender Sep 08 '12 at 05:03

It seems like entire civilizations could conceivably fit into clever Python one-liners. I'm always amazed. – Tim Post Sep 08 '12 at 05:12

This might help:

str.split(str="", num=string.count(str)).
str: any delimeter, by default it is space.

num: number of lines to be made.

You can get more info here.

This doesn't answer the question, which is about splitting into strings of a given length rather than by a delimiter – David Robinson Sep 08 '12 at 04:53

It's nice that you did a search to help the question author, but simply copying the first result you find without any explanation (even with citation) really isn't helping. The OP might just use `8` for the delimiter and think it works. – Tim Post Sep 08 '12 at 04:54
