Session 41
Practice
Avinash wants to help his sister mounika to pass through the aptitude exam, so in order to help her he wants to test her skills in english .So he fixed to assign some sentences and want the key root words in the sentences. So write a python code that helps mounika to get the root words in the given sentences?(Note:Use stemming and tokenization process)
Avinash is a comic editor in a X company one day while editing a particular script he became enthusiastic about the story of the script so there is no time to read the whole script he decided to understand the total story line by learning about the characters so he wants to separate the words in the sentence to know the characters as the whole story is complex ,So write a python program that splits the words and display both splitted words and count of the words in the given sentence using tokenizer function?
Avinash is a English teacher in a school.She wants to teach the students about connectors and prepositions and there usage in sentence formation so she thought an idea that helps students to understand more about the connectors and prepositions so he planned to give different sentences to the students and to remove the connectors and prepositions in the sentence .Write a python code to help students to remove those connectors and prepositions?(Note: connectors and prepositions represents stop words take them in a text file for required output)
