shuffle train and test set python code example

Example 1: test_size

This parameter decides the size of the data that has to be split as the test dataset. This is given as a fraction. For example, if you pass 0.5 as the value, the dataset will be split 50% as the test dataset. If you’re specifying this parameter, you can ignore the next parameter.

Example 2: train slipt sklearn

from sklearn.model_selection import train_test_split 

X_train, X_test, y_train, y_test = train_test_split(
    X, y, test_size=0.33, random_state=42)
