Python | Split string in groups of n consecutive characters

Given a string (be it either string of numbers or characters), write a Python program to split the string by every n^th character.

Examples:

Input : str = "Geeksforgeeks", n = 3
Output : ['Gee', 'ksf', 'oor', 'gee', 'ks']

Input : str = "1234567891234567", n = 4
Output : [1234, 5678, 9123, 4567]

Method #1: Using list comprehension

# Python code to split string 
# by every 3th number 
  
# String initialization 
string = "Geeksforgeeks"
  
# Defining splitting point 
n = 3
  
# Using list comprehension 
out = [(string[i:i+n]) for i in range(0, len(string), n)] 
  
# Printing output 
print(out) 

Output:

['Gee', 'ksf', 'org', 'eek', 's']

Method #2: Using zip_longest

# Python code to split string of number 
# and character into every 4th number 
  
# Importing 
from itertools import zip_longest 
  
# Group function using zip_longest to split 
def group(n, iterable, fillvalue=None): 
    args = [iter(iterable)] * n 
    return zip_longest(fillvalue=fillvalue, *args) 
  
# String initialization 
str = '123GeeksForGeeks4567'
  
# Split point 
n=4
  
# list of seperated string 
out_string = [''.join(lis) for lis in group(n, str, '')] 
  
# Output list initialization 
out_no = [] 
  
# Converting list of string into list of integer 
for a in out_string: 
    out_no.append(a) 
  
# Printing list 
print(out_no) 

Output:

['123G', 'eeks', 'ForG', 'eeks', '4567']
