DuksTools 0.1.16

Modular and extensible data preprocessing library

🪿🪿 DucksTools 🛠️🛠️

Modular and Extensible Data Preprocessing Library for Machine Learning

DucksTools is a plug-and-play, mixin-based Python library that streamlines the preprocessing of tabular datasets for machine learning tasks. Whether you’re cleaning messy data, encoding categories, transforming skewed distributions, or scaling features — this package has you covered.

---

🚀 Features

• 🧼 Handle missing data
• 🔢 Convert object columns to numeric
• 🔍 Identify feature types (categorical, ordinal, nominal, etc.)
• ⚙️ Encode nominal and ordinal features
• 🔄 Transform skewed and heavy-tailed features
• 📏 Scale features with standard or power transformations
• 🧪 Train-test split with optional oversampling
• 📊 Transformation logs for transparency and reproducibility
• 🔌 Built using Mixins for modular extension

⚙️ Installation

You can install the package directly from PyPI:

pip install DucksTools

Or, after building your wheel file (.whl) from the source:

pip install dist/DucksTools-0.1.8-py3-none-any.whl

Or install directly in editable mode (for development):

pip install -e .

🧪 Usage

import DucksTools as gt

# Instantiate with a dataset
obj = gt(
    dataframe=df,
    target_variable='target',
    ordinal_features=['education_level'],
    ordinal_categories=[['Low', 'Medium', 'High']],
    use_one_hot_encoding=True
)

# Apply full preprocessing pipeline
X_train, X_test, y_train, y_test = obj.pre_process()

# Access logs
print(obj.transformation_log_df)

---

🗂 Default Sample Dataset

If no DataFrame is provided, the processor loads a built-in heart.csv dataset:

obj = DucksTools()  # Uses sample heart dataset

# Apply full preprocessing pipeline
X_train, X_test, y_train, y_test = obj.pre_process()
