Hands-On Tutorial: Basic Predictive Analytics with Python

Here’s a simple example of predictive analytics using Python:

import pandas as pd

from sklearn.linear_model import LinearRegression

# Sample data

data = {'Month': [1, 2, 3, 4, 5], 'Sales': [100, 120, 130, 150, 170]}

df = pd.DataFrame(data)

# Prepare model

X = df[['Month']]

y = df['Sales']

model = LinearRegression()

model.fit(X, y)

# Predict for next month

next_month = [[6]]

predicted_sales = model.predict(next_month)

print(f"Predicted sales for month 6: {predicted_sales[0]:.2f}")

This code demonstrates how to build a simple linear regression model for sales forecasting. Skills like this are taught in many data analytics certification programs.
