### Explanation of the Code Structure

**Imports:**
- Only essential libraries (`pandas` and `numpy`) are imported. `matplotlib` and `seaborn` were removed as they are typically used for visualization, which is outside the scope of feature engineering.

**Status Function:**
- A helper function `status` is defined to print the status of each processed feature.

**Feature Engineering Functions:**

**Data Loading:**
- `get_combined_data` loads and combines the train and test datasets.

**Title Extraction:**
- `extract_titles` extracts titles from the 'Name' column and maps them to standardized categories.

**Missing Value Handling:**
- `fill_missing_ages` fills missing 'Age' values based on grouped medians.
- `fill_missing_fares` fills missing 'Fare' values with the mean fare from the training set.

**Encoding Categorical Variables:**
- `encode_sex` encodes the 'Sex' column.
- `encode_pclass` encodes the 'Pclass' column using dummy variables.
- `encode_ticket` extracts ticket prefixes and encodes them using dummy variables.
- `encode_cabin` extracts the first letter of the 'Cabin' column and encodes it.
- `encode_embarked` encodes the 'Embarked' column using dummy variables.

**Family Features:**
- `process_family` creates family-related features based on 'SibSp' and 'Parch'.

**Main Feature Engineering Pipeline:**
- The `feature_engineering` function orchestrates the entire pipeline by sequentially calling each feature engineering function.

**Execution Block:**
- When the script is run directly, it executes the `feature_engineering` function and prints the shape and head of the resulting DataFrame.

### Usage Instructions

**Save the Script:**
- Save the above code in a file named `Feature_engineering.py`.

**Directory Structure:**
- Ensure that your data files are located in the `./data/` directory relative to where the script is run.
- The default paths are `./data/train.csv` and `./data/test.csv`. Modify these paths if your data is located elsewhere.

**Running the Script:**
- To execute the feature engineering pipeline and see the output, run the script from the command line:
  ```sh
  python Feature_engineering.py
  ```

**Importing as a Module:**
- You can also import the `feature_engineering` function into other scripts or notebooks:
  ```python
  from Feature_engineering import feature_engineering

  combined_data, target = feature_engineering(train_path='path_to_train.csv', test_path='path_to_test.csv')
  ```

### Additional Recommendations

**Logging:**
- For more advanced status tracking, consider integrating Python's logging module instead of simple print statements.

**Error Handling:**
- Implement error handling to manage unexpected issues, such as missing columns or incorrect data types.

**Configuration:**
- Use configuration files or environment variables to manage file paths and other settings, enhancing flexibility.

**Testing:**
- Incorporate unit tests to ensure each function behaves as expected, enhancing the reliability of your feature engineering pipeline.

**Documentation:**
- Consider adding more detailed documentation or using tools like Sphinx to generate comprehensive module documentation.

This structured approach will make your feature engineering process more maintainable, reusable, and scalable.


Q- next this the modling part oky 

“III - Modeling
In this part, we use our knowledge of the passengers based on the features we created and then build a statistical model. You can think of this model as a box that crunches the information of any new passenger and decides whether or not he survives.
There is a wide variety of models to use, from logistic regression to decision trees and more sophisticated ones such as random forests and gradient boosted trees.
We'll be using Random Forests. Random Froests has proven a great efficiency in Kaggle competitions.
For more details about why ensemble methods perform well, you can refer to these posts:
http://mlwave.com/kaggle-ensembling-guide/
http://www.overkillanalytics.net/more-is-always-better-the-power-of-simple-ensembles/
Back to our problem, we now have to:
Break the combined dataset in train set and test set.
Use the train set to build a predictive model.
Evaluate the model using the train set.
Test the model using the test set and generate and output file for the submission.
Keep in mind that we'll have to reiterate on 2. and 3. until an acceptable evaluation score is achieved.
Let's start by importing the useful libraries.
In [61]:
from sklearn.pipeline import make_pipeline
from sklearn.ensemble import RandomForestClassifier
from sklearn.ensemble.gradient_boosting import GradientBoostingClassifier
from sklearn.feature_selection import SelectKBest
from sklearn.model_selection import StratifiedKFold
from sklearn.model_selection import GridSearchCV
from sklearn.model_selection import cross_val_score
from sklearn.feature_selection import SelectFromModel
from sklearn.linear_model import LogisticRegression, LogisticRegressionCV


To evaluate our model we'll be using a 5-fold cross validation with the accuracy since it's the metric that the competition uses in the leaderboard.
To do that, we'll define a small scoring function.
In [62]:
def compute_score(clf, X, y, scoring='accuracy'):
    xval = cross_val_score(clf, X, y, cv = 5, scoring=scoring)
    return np.mean(xval)


Recovering the train set and the test set from the combined dataset is an easy task.
In [63]:
def recover_train_test_target():
    global combined
    
    targets = pd.read_csv('./data/train.csv', usecols=['Survived'])['Survived'].values
    train = combined.iloc[:891]
    test = combined.iloc[891:]
    
    return train, test, targets


In [64]:
train, test, targets = recover_train_test_target()


Feature selection
We've come up to more than 30 features so far. This number is quite large.
When feature engineering is done, we usually tend to decrease the dimensionality by selecting the "right" number of features that capture the essential.
In fact, feature selection comes with many benefits:
It decreases redundancy among the data
It speeds up the training process
It reduces overfitting
Tree-based estimators can be used to compute feature importances, which in turn can be used to discard irrelevant features.
In [65]:
clf = RandomForestClassifier(n_estimators=50, max_features='sqrt')
clf = clf.fit(train, targets)


Let's have a look at the importance of each feature.
In [66]:
features = pd.DataFrame()
features['feature'] = train.columns
features['importance'] = clf.feature_importances_
features.sort_values(by=['importance'], ascending=True, inplace=True)
features.set_index('feature', inplace=True)


In [67]:
features.plot(kind='barh', figsize=(25, 25))



As you may notice, there is a great importance linked to Title_Mr, Age, Fare, and Sex.
There is also an important correlation with the Passenger_Id.
Let's now transform our train set and test set in a more compact datasets.
In [68]:
model = SelectFromModel(clf, prefit=True)
train_reduced = model.transform(train)
print train_reduced.shape


(891L, 14L)


In [69]:
test_reduced = model.transform(test)
print test_reduced.shape


(418L, 14L)


Yay! Now we're down to a lot less features.
We'll see if we'll use the reduced or the full version of the train set.
Let's try different base models
In [70]:
logreg = LogisticRegression()
logreg_cv = LogisticRegressionCV()
rf = RandomForestClassifier()
gboost = GradientBoostingClassifier()

models = [logreg, logreg_cv, rf, gboost]


In [71]:
for model in models:
    print 'Cross-validation of : {0}'.format(model.__class__)
    score = compute_score(clf=model, X=train_reduced, y=targets, scoring='accuracy')
    print 'CV score = {0}'.format(score)
    print '****'


Cross-validation of : <class 'sklearn.linear_model.logistic.LogisticRegression'>
CV score = 0.817071431282

### Python Scripts for Modeling Algorithms

#### 1. Logistic Regression (`model_logistic_regression.py`)

This script performs logistic regression with the following steps:
- Imports necessary libraries.
- Loads and preprocesses the data using a feature engineering function.
- Splits the dataset into training and test sets.
- Selects important features using a RandomForest classifier.
- Trains a logistic regression model, performs cross-validation, and generates predictions.

    scores = cross_val_score(clf, X, y, cv=5, scoring=scoring)
    return np.mean(scores)

def recover_train_test(combined, targets):
    train = combined.iloc[:len(targets)]
    test = combined.iloc[len(targets):]
    return train, test, targets

def main():
    combined, targets = feature_engineering()
    train, test, targets = recover_train_test(combined, targets)
