Pseudocode

1. Import necessary libraries.
2. Load and preprocess the dataset.
3. Split the dataset into training and testing sets.
4. Train a classification model (e.g., Random Forest).
5. Evaluate the model’s performance.
6. Make predictions on new data.

Python Code

Import necessary libraries
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score, classification_report

Load the dataset
data = pd.read_csv('customer_churn.csv')

Preprocess the dataset (example: handle missing values, encode categorical variables)
data.fillna(method='ffill', inplace=True)
data = pd.get_dummies(data, drop_first=True)

Split the dataset into features and target variable
X = data.drop('churn', axis=1)
y = data['churn']

Split the data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

Train a Random Forest Classifier
model = RandomForestClassifier(n_estimators=100, random_state=42)
model.fit(X_train, y_train)

Make predictions on the test set
y_pred = model.predict(X_test)

Evaluate the model's performance
accuracy = accuracy_score(y_test, y_pred)
report = classification_report(y_test, y_pred)

print(f'Accuracy: {accuracy}')
print('Classification Report:')
print(report)
