Python | Ways to split a string in different ways

The most common problem we have encountered in Python is splitting a string by a delimeter, But in some cases we have to split in different ways to get the answer. In this article, we will get substrings obtained by splitting string in different ways.

Examples:

Input : Paras_Jain_Moengage_best
Output : [‘Paras’, ‘Paras_Jain’, ‘Paras_Jain_Moengage’, ‘Paras_Jain_Moengage_best’]

Input : chunky_2808_GFG_Codechef
Output : [‘chunky’, ‘chunky_2808’, ‘chunky_2808_GFG’, ‘chunky_2808_GFG_Codechef’]

Below are some ways to do the task.

Method #1: Using Iteration

# Python code to split string in substring manner
  
# Input initialisation
Input = "Geeks_for_geeks_is_best"
  
# Split initialise
split_string = Input.split('_')
  
# Output list initialise
Output = []
  
# Iteration
for a in range(len(split_string)):
    temp = split_string[:a + 1]
    temp = "_".join(temp)
    Output.append(temp)
  
# print output
print(Output)

Output:

[‘Geeks’, ‘Geeks_for’, ‘Geeks_for_geeks’, ‘Geeks_for_geeks_is’, ‘Geeks_for_geeks_is_best’]

# Python code to split string in substring manner
  
# Importing 
from itertools import accumulate
  
# Input initialisation
Input = "Geeks_for_geeks_is_best"
  
# Using accumulate
Output = [*accumulate(Input.split('_'), lambda temp1, temp2 :
                                   '_'.join([temp1, temp2])), ]
  
# Printing output
print(Output)

Output:

[‘Geeks’, ‘Geeks_for’, ‘Geeks_for_geeks’, ‘Geeks_for_geeks_is’, ‘Geeks_for_geeks_is_best’]
