print(f"Memory usage: {df.memory_usage(deep=True).sum() / 1024**2:.2f} MB")
print("\nColumn types:")
print(df.dtypes)
print("\nFirst few rows:")
display(df.head())
```

### EDA Section
```python
# =============================================================================
# EXPLORATORY DATA ANALYSIS
# =============================================================================

## Missing Values
missing = df.isnull().sum()
missing_pct = 100 * missing / len(df)
missing_table = pd.DataFrame({
    'Missing_Values': missing,
    'Percentage': missing_pct
}).sort_values('Percentage', ascending=False)
print("Missing values:")
display(missing_table[missing_table['Percentage'] > 0])

## Numeric Features Distribution
numeric_features = df.select_dtypes(include=[np.number]).columns
df[numeric_features].hist(bins=30, figsize=(20, 15))
plt.suptitle('Distribution of Numeric Features')
plt.tight_layout()
plt.show()

## Correlation Analysis
plt.figure(figsize=(12, 10))
sns.heatmap(df[numeric_features].corr(), annot=True, fmt='.2f', cmap='coolwarm')
plt.title('Correlation Matrix')
plt.show()
```

### Modeling Section
```python
# =============================================================================
# MODEL TRAINING
# =============================================================================

## Prepare features and target
X = df.drop('target', axis=1)
y = df['target']

## Train/test split
X_train, X_test, y_train, y_test = train_test_split(
    X, y,
    test_size=0.2,
    random_state=RANDOM_SEED,
    stratify=y
)

print(f"Training set size: {X_train.shape}")
print(f"Test set size: {X_test.shape}")

## Train model
model = RandomForestClassifier(
    n_estimators=100,
    random_state=RANDOM_SEED,
    n_jobs=-1
)

model.fit(X_train, y_train)

## Evaluate
train_score = model.score(X_train, y_train)

## Best Practices Included in Templates

1. **All imports at the top**: Organized by category
2. **Configuration section**: Paths, seeds, constants defined early
3. **Markdown documentation**: Every section explained
4. **Reproducibility**: Random seeds set, environment documented
5. **Clean outputs**: Appropriate use of print vs display
6. **Visualization standards**: Titles, labels, legends on all plots
7. **Error handling**: Try/except blocks where appropriate
8. **Memory efficiency**: Display settings, data types considered
9. **Modular code**: Helper functions defined in setup
10. **Clear conclusions**: Findings documented at end

## Creating New Notebooks from Templates

### Using /create-notebook command:
```bash
/create-notebook eda customer_analysis
```

### Manual creation:
```python
import nbformat as nbf

# Create new notebook
nb = nbf.v4.new_notebook()

# Add cells
nb['cells'] = [
    nbf.v4.new_markdown_cell("# Title"),
    nbf.v4.new_code_cell("import pandas as pd"),
    # ... more cells
]

# Write to file
with open('notebook.ipynb', 'w') as f:
    nbf.write(nb, f)
```

## Customization Guidelines

When customizing templates:
1. Keep the overall structure
2. Modify section titles as needed
3. Add domain-specific imports
4. Include custom helper functions
5. Update paths and configuration
6. Adjust visualizations for your data
7. Keep markdown documentation updated

## Template Variables

Templates include placeholders for easy customization:
- `[PROJECT_NAME]`: Replace with project name
- `[AUTHOR]`: Replace with author name
- `[DATE]`: Replace with current date
- `[DATA_PATH]`: Update with actual data path
- `[TARGET_VARIABLE]`: Update with target column name

## When to Use This Skill

- User starts a new analysis
- User needs a standardized notebook format
- User asks to create EDA, modeling, or evaluation notebook
- User wants to ensure best practices
- User needs to onboard team members with consistent structure
- User wants to save time on boilerplate code

## Template Files Location

Templates are stored in `notebooks/templates/`:
- `eda_template.ipynb` - Exploratory Data Analysis
- `modeling_template.ipynb` - Model training and tuning
- `evaluation_template.ipynb` - Model evaluation and comparison
- `preprocessing_template.ipynb` - Data preprocessing
- `feature_engineering_template.ipynb` - Feature creation
- `report_template.ipynb` - Results reporting

## Example Usage Workflow

1. User: "I need to start EDA on customer data"
2. Agent: Uses skill to provide EDA template
3. Template includes: imports, data loading, profiling, visualization, insights
4. User fills in data-specific details
5. Result: Professional, reproducible EDA notebook

Remember: Good templates save time and ensure consistency. They embody best practices so users don't have to remember them all.
