Given a String, return all the start indices and end indices of each word.
Examples:
Input : test_str = ‘ Geekforgeeks is Best’
Output : [(1, 12), (16, 17), (19, 22)]
Explanation : “Best” Starts at 19th index, and ends at 22nd index.Input : test_str = ‘ Geekforgeeks is Best’
Output : [(1, 12), (17, 18), (20, 23)]
Explanation : “Best” Starts at 20th index, and ends at 23rd index.
Method : Using list comprehension + regex + finditer()
In this, we extract all the words using finditer() and regex, to get initial and end index, we use start() and end() and encapsulate using list comprehension in form of tuple list.
Python3
# Python3 code to demonstrate working of# Word Ranges in String# Using list comprehension + regex + finditer()import re # initializing stringtest_str = ' Geekforgeeks is Best for geeks' # printing original stringprint("The original string is : " + str(test_str)) # regex to get words, loop to get each start and end indexres = [(ele.start(), ele.end() - 1) for ele in re.finditer(r'\S+', test_str)] # printing resultprint("Word Ranges are : " + str(res)) |
The original string is : Geekforgeeks is Best for geeks Word Ranges are : [(1, 12), (16, 17), (19, 22), (27, 29), (32, 36)]
