how to split the data?

Scikit-learn alias sklearn is the most useful and robust library for machine learning in Python. The scikit-learn library provides us with the model_selection module in which we have the splitter function train_test_split().

 

# import modules

import pandas as pd

from sklearn.linear_model import LinearRegression

from sklearn.model_selection import train_test_split

 

# read the dataset

df = pd.read_csv('Real estate.csv')

 

# get the locations

X = df.iloc[:, :-1]

y = df.iloc[:, -1]

 

# split the dataset

X_train, X_test, y_train, y_test = train_test_split(

X, y, test_size=0.05, random_state=0)

In the above example, We import the pandas package and sklearn package. after that to import the CSV file we use the read_csv() method. The variable df now contains the data frame. In the example “house price” is the column we’ve to predict so we take that column as y and the rest of the columns as our X variable. test_size = 0.05 specifies only 5% of the whole data is taken as our test set, and 95% as our train set. The random state helps us get the same random split each time.
