Answer 1

Check this out, just run and enter the substring ("chunk size"). It returns a list of whatever you entered sized substrings of supplied string. Try it with 2 and then w/ 3

Ratnapal Shende Check it out now. It will take any number and seperate the string into chunks of that size. Adding dashes to compensate the missing characters on the last chunk if needed

Answer 2

Using list comprehension combined with range definition.

Answer 3

No problem! And which module do you mean?

Answer 4

imported sys just to exit when i want.
and imported math so i could round up.

its important to round up in order for the code to get and split the entire word

Answer 5

with re module only:

import re
print(re.findall(r'.{1,'+str(chunk_size)+'}',word))

Answer 6

Ratnapal Shende do you know no regular expressions?

first argument of re.findall is the pattern string to be compiled, dynamically build...

it result as ".{1,n}" where n is the chunck size... dot search for any character * (1 to n) times...

re.findall(".{1,3}",text)

will return all 3 length chunck + eventual less than 3 final chunck ;)

Answer 7

Slick

Thank you bro!
bro any simplest way other than using module ?

Answer 8

without using any module

Answer 9

visph
your code seems complicated for me
please explain this syntax

re.findall(r'.{1,'+str(chunk_size)+'}',word))

' } ' quotes ?? 🤔🤔
