Given a String of words, assign index to each word.
Input : test_str = ‘geekforgeeks is best’
Output : {0: ‘geekforgeeks’, 1: ‘is’, 2: ‘best’}
Explanation : Index assigned to each word.Input : test_str = ‘geekforgeeks best’
Output : {0: ‘geekforgeeks’, 1: ‘best’}
Explanation : Index assigned to each word.
Method #1 : Using enumerate() + dict() + split()
In this, we first perform task of split() and then add index component to map each word with index using enumerate().
Python3
# Python3 code to demonstrate working of # Sequence Assignment to Words # Using split() + enumerate() + dict() # initializing string test_str = 'geekforgeeks is best for geeks' # printing original string print("The original string is : " + str(test_str)) # using dict() to convert result in idx:word manner res = dict(enumerate(test_str.split())) # printing result print("The Assigned Sequence : " + str(res)) |
The original string is : geekforgeeks is best for geeks
The Assigned Sequence : {0: 'geekforgeeks', 1: 'is', 2: 'best', 3: 'for', 4: 'geeks'}
Method #2 : Using zip() + count() + dict()
In this, the count() component renders the index logic and pairing of each word to index is done using zip().
Python3
# Python3 code to demonstrate working of # Sequence Assignment to Words # Using zip() + count() + dict() from itertools import count # initializing string test_str = 'geekforgeeks is best for geeks' # printing original string print("The original string is : " + str(test_str)) # using dict() to convert result in idx:word manner # count() from itertools used for this task res = dict(zip(count(), test_str.split())) # printing result print("The Assigned Sequence : " + str(res)) |
The original string is : geekforgeeks is best for geeks
The Assigned Sequence : {0: 'geekforgeeks', 1: 'is', 2: 'best', 3: 'for', 4: 'geeks'}
