user_item_matrix = np.array([[1, 0, 3, 4],
                             [2, 1, 0, 3],
                             [0, 4, 2, 0]])

# Calculate cosine similarity
item_similarity = cosine_similarity(user_item_matrix.T)

# Generate recommendations for a user
user_id = 0
user_ratings = user_item_matrix[user_id]
recommendations =, user_ratings) / np.sum(np.abs(item_similarity), axis=1)
print("Recommendations:", recommendations)

1.2. Sentiment Analysis for Better Customer Understanding

Understanding customer sentiments is crucial for businesses to improve products and services. Sentiment analysis, a natural language processing technique, helps in gauging public opinions from social media, reviews, and other textual data. Python’s NLTK library can be used to perform sentiment analysis:

from nltk.sentiment import SentimentIntensityAnalyzer

text = "The new product exceeded my expectations. The quality is impressive!"

analyzer = SentimentIntensityAnalyzer()
sentiment_scores = analyzer.polarity_scores(text)

if sentiment_scores['compound'] > 0:
    sentiment = "positive"
elif sentiment_scores['compound'] < 0:
    sentiment = "negative"
    sentiment = "neutral"

print("Sentiment:", sentiment)

import matplotlib.pyplot as plt

# Load historical stock data
data = pd.read_csv("stock_data.csv")
data['Date'] = pd.to_datetime(data['Date'])
data.set_index('Date', inplace=True)

# Calculate moving averages
data['50_MA'] = data['Close'].rolling(window=50).mean()
data['200_MA'] = data['Close'].rolling(window=200).mean()

# Implement trading strategy
data['Signal'] = np.where(data['50_MA'] > data['200_MA'], 1, -1)

# Visualize strategy
plt.figure(figsize=(12, 6))
plt.plot(data.index, data['Close'], label='Stock Price')
plt.plot(data.index, data['50_MA'], label='50-day MA')
plt.plot(data.index, data['200_MA'], label='200-day MA')
plt.plot(data[data['Signal'] == 1].index, data[data['Signal'] == 1]['Close'], '^', markersize=10, color='g', label='Buy Signal')
plt.plot(data[data['Signal'] == -1].index, data[data['Signal'] == -1]['Close'], 'v', markersize=10, color='r', label='Sell Signal')
