how to split data in python code example

Example 1: train test split python

from sklearn.model_selection import train_test_split
				
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=42)

Example 2: pandas split train test

from sklearn.model_selection import train_test_split


y = df.pop('output')
X = df

X_train,X_test,y_train,y_test = train_test_split(X.index,y,test_size=0.2)
X.iloc[X_train] # return dataframe train

Example 3: how to split a string in python

sample_str = "Help developers by donating!"
txt.split(' ')

Example 4: splitting data into training and testing sklearn

train_features, test_features, train_labels, test_labels = 
train_test_split(features, labels)
#This is using sklearn
