To generate n-grams from a list of tokens with a specified value of n
What is the purpose of the generate_ngrams() function?
To generate n-grams from the input text and store them in a list
What is the purpose of the word_tokenize() function from the nltk module?
To convert the input text into a list of words (tokens)
What is the value of the ngrams_list variable after executing the line ngrams_list = generate_ngrams(text, n)?
A list of n-grams generated from the user-provided text with the specified value of n

To prompt the user to enter the value of n for n-gram generation and convert it to an integer
Study Notes
Word Analysis in Python
- The program uses NLTK library for word analysis
- It prompts the user to enter a sentence or text for analysis
- The input text is tokenized using the
word_tokenizefunction - A frequency distribution object is created using the
FreqDistfunction - The program prints the five most common words and their frequency using the
most_commonmethod
Word Generation in Python
- The program generates text based on user input
- It prompts the user to enter a text and the number of words to generate
- The input text is tokenized and an
nltk.Textobject is created - The
generatemethod is used to generate text with the specified length - The generated text is printed to the console
Morphology in Python
- The program uses NLTK library for morphology
- The WordNet corpus is downloaded using
nltk.download - The
WordNetLemmatizerandword_tokenizeclasses are imported from NLTK - The program prompts the user to enter a sentence and lemmatizes each token
- The lemmatized tokens are printed to the console
N-Grams in Python
- The program generates n-grams from user input
- The
ngramsfunction is used to generate n-grams from tokenized text - The program prompts the user to enter a text and the value of n for n-gram generation
- The generated n-grams are printed to the console
N-Gram Smoothing in Python (Note: The text does not provide a program for n-gram smoothing)
Learn how to write a Python program for Word Analysis using the nltk library. The program involves importing necessary modules, tokenizing words, and analyzing word frequency.
