.........................Is a library for Machine Learning (ML) in Python. It has useful functions for building ML models.

• matplotlib

• scikit learn

What is the function can used forData splitting (Take part of the data for training and part for testing)

• train_test_split()

• import pandas as pd

To create and train a decision tree model, the sub-package ----------- needs to be imported from the scikit learn library

• predict

• tree

After the model is trained, the ---------------function is used to predict the label of the testing dataset

• predict()

• tree

After testing the decision tree classifier, it should be evaluated using accuracy by comparing the predictions with actual results.You can find the accuracy using------------ function from scikit learn

• the accuracy_score()

• tree()

which code is the correct code if i want to store dataframe :

• red_data= pd.Dataframa([[250,20,50],[190,10,20],[220,20,40],[240,30,35][250,60,50]])

• pd.Dataframared_data ([[250,20,50],[190,10,20],[220,20,40],[240,30,35][250,60,50]])

which code is the correct code if i want to add headers and labels:

• red_data.column=["R","G","B"]

• red_data =["R","G","B"]
