Extract Each Word From List Of Strings

I am using Python my list is str = ['Hello dude', 'What is your name', 'My name is Chetan'] I want to separate each word in each sentence in the string and store it in new_list. n

Solution 1:

You could use itertools.chain

from itertools import chain

def split_list_of_words(list_):
    return list(chain.from_iterable(map(str.split, list_)))

DEMO

input_ = [
          "Hello dude", 
          "What is your name", 
          "My name is Chetan"
         ]

result = split_list_of_words(input_)

print(result)
#['Hello', 'dude', 'What', 'is', 'your', 'name', 'My', 'name', 'is', 'Chetan']

Solution 2:

you have,

values = ["Hello dude", "What is your name", "My name is Chetan"]

then use this one liner

' '.join(values).split()

Solution 3:

This should help. Instead of append use extend or +=

str = ["Hello dude", "What is your name", "My name is Chetan"]
new_list = []
for row in str:
    new_list += row.split(" ") #or new_list.extend(row.split(" "))

print new_list

Output:

['Hello', 'dude', 'What', 'is', 'your', 'name', 'My', 'name', 'is', 'Chetan']

Solution 4:

new_list = [x for y in str for x in y.split(" ")]

Solution 5:

You are almost there. All that's left to do is to un-nest your list.

final_result = [x for sublist in new_list for x in sublist]

Or without a list comprehension:

final_result = []
for sublist in new_list:
    for x in sublist:
        final_result.append(x)

Of course, all of this can be done in a single step without producing new_list first explicitly. The other answers already covered that.
