Given a list of strings. The task is to split the string by the given list of strings.
Input : test_str = ‘geekforgeeksbestforgeeks’, sub_list = [“best”]
Output : [‘geekforgeeks’, ‘best’, ‘forgeeks’]
Explanation : “best” is extracted as different list element.Input : test_str = ‘geekforgeeksbestforgeeksCS’, sub_list = [“best”, “CS”]
Output : [‘geekforgeeks’, ‘best’, ‘forgeeks’, “CS”]
Explanation : “best” and “CS” are extracted as different list element.
Method : Using re.split() + | operator
In this, we perform the task of split using regex split() with | operator to check for all the words that need to be put separately.
Python3
# Python3 code to demonstrate working of # Separate specific Strings # Using re.split() + | operator import re # initializing string test_str = 'geekforgeeksisbestforgeeks' # printing original String print("The original string is : " + str(test_str)) # initializing list words sub_list = ["best"] # regex to for splits() # | operator to include all strings temp = re.split(rf"({'|'.join(sub_list)})", test_str) res = [ele for ele in temp if ele] # printing result print("The segmented String : " + str(res)) |
The original string is : geekforgeeksisbestforgeeks The segmented String : ['geekforgeeksis', 'best', 'forgeeks']
