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 nth 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 3rd 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 separated 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']
