How to encode text to numeric using fit_transform

 Hi all,

Qn) How to encode text to numeric using fit_transform

Ans)

import numpy as np

import pandas as pd

from sklearn.feature_extraction.text import CountVectorizer

df = pd.read_csv("hupassg.tsv", sep='\t', encoding='ISO-8859-1');

vectorizer1 = CountVectorizer(max_features = 10000, ngram_range=(1, 3), stop_words='english')

count_vector1 = vectorizer1.fit_transform(df['clean_assg'])

feature_names1 = vectorizer1.get_feature_names_out()

data1 = df[['assg_set','clean_assg','final_score']].copy()

X = count_vectors1.toarray()

y = data1['final_score'].to_numpy()

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.3)
