Split string every n characters using python

Introduction

This article will teach you to split strings every n characters using python. If you are trying to know how we can split string every n characters using python, this article should help you. You will learn the easiest methods to do this with re library or even without it.

How to split string every n characters using python

We are able to split string every n character with or without modules. In fact, we will learn how to do both. A regular expression (or RE) indicates a set of strings that matches it; the capacities in this module let you check in the event that a specific string matches a given regular expression (or in case a given customary expression matches a specific string, which comes down to the same thing).

Regular expressions can be concatenated to create modern regular expressions; in the event that A and B are both regular expressions, at that point, AB is additionally a regular expression. In common, on the off chance that a string p matches A and another string q matches B, the string pq will coordinate AB. This holds unless A or B contain moo priority operations; boundary conditions between A and B; or have numbered bunch references.

Hence, complex expressions can easily be developed from less complex primitive expressions just like the ones depicted here. For points of interest of the hypothesis and usage of normal expressions, counsel the Friedl book [Frie09], or nearly any reading material approximately compiler construction. A brief clarification of the arrangement of standard expressions takes after. For f

In fact, we are able to do this with list indexing too! Let’s know more about indexing.

Indexing in Python could be a way to allude the person things inside an iterable by its position. In other words, you'll be able straightforwardly get to your components of choice inside an iterable and do different operations depending on your needs.

Now, let’s move to the solutions

Solution 1

This solution will be with indexing.

>>> line = '1234567890'
>>> n = 2
>>> [line[i:i+n] for i in range(0, len(line), n)]
 ['12', '34', '56', '78', '90']

Solution 2

>>> import re
>>> re.findall('..','1234567890')
 ['12', '34', '56', '78', '90']

If the number of characters is odd we can do the following:

>>> import re
>>> re.findall('..?','1234567890')
 ['12', '34', '56', '78', '90']

And also the following:

>>> import re
>>> re.findall('.{1,2}','1234567890')
['12', '34', '56', '78', '90']

In general

We can use re or not to split string every n characters using python

Conclusion

Using python, the most straightforward methods to make your code split string every n characters are indexing and regular expressions. In fact, these 2 solutions are easy and don’t require new modules to download.
