Given a Sentence, write a Python program to convert the given sentence into list of words. 

Examples: 

Input : ['Hello World']
Output : ['Hello', 'world']

Input : ['Geeks For geeks']
Output : ['Geeks', 'for', 'geeks']

The simplest approach provided by Python to convert the given list of Sentence into words with separate indices is to use split() method. This method split a string into a list where each word is a list item. We have alternative ways to use this function in order to achieve the required output.

Method #1 : Splitting the first index element 

Python3




# Python3 program to Convert single
# indexed list into multiple indexed list
 
def convert(lst):
    return (lst[0].split())
 
# Driver code
lst =  ["Geeks For geeks"]
print( convert(lst))
Output: 
['Geeks', 'For', 'geeks']

 

Method #2 : Using for loop 
We can also use a for loop to split the first element. This method is also beneficial if we have more than one element.  

Python3




# Python3 program to Convert single
# indexed list into multiple indexed list
 
def convert(lst):
    return ([i for item in lst for i in item.split()])
     
# Driver code
lst =  ['Geeksforgeeks is a portal for geeks']
print( convert(lst))
Output: 
['Geeksforgeeks', 'is', 'a', 'portal', 'for', 'geeks']

 

Method #3 : Using join() 
We can split the given list and than join using join() function. We can also use this when you have a list of string or single string inside a list.  

Python3




# Python3 program to Convert single
# indexed list into multiple indexed list
 
def convert(lst):
    return ' '.join(lst).split()
     
 
# Driver code
lst =  ['Hello Geeks for geeks']
print( convert(lst))
Output: 
['Hello', 'Geeks', 'for', 'geeks']
