If you wish to know how, then here’s a breakdown for building a churn prediction system that uses Python for data preparation and model building (outside of Tableau):

a. Data Preparation and Model Building (Python – Outside Tableau)

Step 1: Gather Data

Collect user activity data, including:

• Login frequency
• Feature usage (e.g., time spent on specific features)
• Support ticket submissions
• Plan changes
• Billing information
• Customer demographics (e.g., industry and company size)
• Subscription start date

Step 2: Clean and Engineer Features

• Handle missing values (such as imputation and deletion).
• Convert categorical variables to numerical (e.g., one-hot encoding and label encoding).
• Create relevant features (e.g., days since last login, average feature usage per day, and time since last support ticket).

Step 3: Train a Scikit-learn Model

• Split data into training and testing sets.
• Choose a suitable model (e.g., Logistic Regression, Random Forest, and Gradient Boosting).
• Train the model on the training data.
• Evaluate the model’s performance (accuracy, precision, recall, F1-score, AUC).
• Save the trained model with pickle.

Here’s a Python script that outlines the process of building and saving a machine learning model for churn prediction:
