split string by comma so that each sentence will be a separate string

Yes it's possible, we have answers already given above but to match exact expected output as mentioned above use below:

inputlist = "apple,banana,cherry"
print(*[[s] for s in inputlist.split(',')],end=" ")

output:

['apple'] ['banana'] ['cherry'] 

You just turn into a list of list with this

text = 'My cat is a great cat, this is very nice, you are doing great job'
text = [[x] for x in text.split(", ")]

You can do

text = list(map(lambda x: [x], text.split(',')))

print(text)

[['My cat is a great cat'], [' this is very nice'], [' you are doing great job']]

You need to insert each item in a list. You can use str.strip() for removing spaces.

>>> text = 'My cat is a great cat, this is very nice, you are doing great job'
>>> [[i.strip()] for i in text.split(',')]

[['My cat is a great cat'], ['this is very nice'], ['you are doing great job']]

Try this, this will put every element of the list into a list

text = 'My cat is a great cat, this is very nice, you are doing great job'

 text = [ [i] for i in text.split(',')]

Didn't know if you wanted this in tensorflow. But if so, here's how you do it,

import tensorflow as tf

text = tf.constant('My cat is a great cat, this is very nice, you are doing great job')

tf.strings.split(text, sep=',')[:, tf.newaxis]

Also, I wonder if your question was about splitting and getting rid of space after the comma. If that's what you needed,

tf.strings.split(text, sep=', ')
