GeeseTools 0.1.21

Modular and extensible data preprocessing library

🪿GeeseTools🛠

Modular and Extensible Data Preprocessing Library for Machine Learning

GeeseTools 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 GeeseTools

---

Usage

import GeeseTools 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 = GeeseTools()  # Uses sample heart dataset

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