train_test_split not random code example

Example 1: train_test_split without shuffle

from sklearn.model_selection import train_test_split
train_test_split(X, y, test_size=0.2, shuffle=False)

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)
