Try:

from sklearn.linear_model import LinearRegression
import numpy as np
regression_model = LinearRegression()
Year = np.array([[1970], [1971], [1972]]) #your data
Income = np.array([3399.299037, 3768.297935, 4251.175484]) #your data
regression_model.fit(Year, Income)
regression_model.predict([[1973]]) #make predictions

Try following this tutorial. https://towardsdatascience.com/linear-regression-using-python-b136c91bf0a2

Here years will be your input variable and income will be the target you are trying to predict. You can use R^2 as an evaluation measure to see how well your model is predicting. Keep the last 10 years for testing to check how well it performs on test set

try like this

import pandas result = pandas.read_csv('C:\Users\Desktop\teri.csv') print(result) regression_model.fit(Year, Income) regression_model.predict([[2019]])

Out[26]: array([32536.51562343])
