Given a String perform division into K equal chunks.
Input : test_str = ‘geeksforgeek’, K = 4
Output : [‘gee’, ‘ksf’, ‘org’, ‘eek’]
Explanation : 12/4 = 3, length of each string extracted.Input : test_str = ‘geeksforgeek’, K = 1
Output : [‘geeksforgeek’]
Explanation : 12/1 = 12, whole string is single chunk.
Method #1 : Using len() + loop
In this, we first perform task of computation of length of each chunk required from K and string length, post that, string is splitted on desired indices to extract chunks using slicing.
Python3
# Python3 code to demonstrate working of # Divide String into Equal K chunks # Using len() + loop # initializing strings test_str = 'geeksforgeeks 1' # printing original string print("The original string is : " + str(test_str)) # initializing K K = 5 # compute chunk length chnk_len = len(test_str) // K res = [] for idx in range(0, len(test_str), chnk_len): # appending sliced string res.append(test_str[idx : idx + chnk_len]) # printing result print("The K chunked list : " + str(res)) |
The original string is : geeksforgeeks 1 The K chunked list : ['gee', 'ksf', 'org', 'eek', 's 1']
Method #2 : Using list comprehension
The method similar to above, difference being that last process is encapsulated to one – liner list comprehension.
Python3
# Python3 code to demonstrate working of # Divide String into Equal K chunks # Using list comprehension # initializing strings test_str = 'geeksforgeeks 1' # printing original string print("The original string is : " + str(test_str)) # initializing K K = 5 # compute chunk length chnk_len = len(test_str) // K # one-liner to perform the task res = [test_str[idx : idx + chnk_len] for idx in range(0, len(test_str), chnk_len)] # printing result print("The K len chunked list : " + str(res)) |
The original string is : geeksforgeeks 1 The K len chunked list : ['gee', 'ksf', 'org', 'eek', 's 1']
