PreprocessingLib
PreprocessingLib is a Python library designed to facilitate data preprocessing steps. It provides various classes and functions to automate the process of cleaning, transforming, and engineering features in datasets.
Features

Missing Value Handling
Detect missing values in a dataset.
Fill missing values using mean, median, or a constant value.
Remove rows or columns with missing values.
Feature Engineering
Create new features based on existing ones.
Date and Time Handling
Extract features like year, month, day, and day of the week from datetime columns.
Data Type Conversion
Convert columns to numeric or categorical data types.
Categorical Encoding
Perform one-hot encoding or label encoding on categorical variables.
Outlier Handling
Detect outliers in numerical data.
Handle outliers by removing or replacing them.
Data Scaling
Standardize or normalize numerical data.
Text Cleaning
Clean text data by removing punctuation, stop words, and lemmatizing words.
Installation
You can install PreprocessingLib using pip:

pip install preprocessinglib
Usage
Here's how you can use PreprocessingLib in your Python projects:
from mypreprocessinglib import FeatureEngineer, MissingValueHandler, DateTimeHandler, DataTypeConverter, CategoricalEncoder, OutlierHandler, Scaler, TextCleaner
import pandas as pd
Load sample dataset
data = pd.read_csv("sample_dataset.csv")
Example usage of preprocessing functions
missing_handler = MissingValueHandler()
filled_data = missing_handler.fill_missing_values(data)
data_with_new_features = FeatureEngineer.create_new_features(data, column1='Column1', column2='Column2')
date_with_features = DateTimeHandler.extract_date_features(data, column='DateColumn')
numeric_data = DataTypeConverter.convert_to_numeric(data, columns=['Column1', 'Column2'])
encoded_data = CategoricalEncoder.one_hot_encode(data, columns=['CategoricalColumn'])
outliers_removed_data = OutlierHandler.handle_outliers(data, method='drop')
scaled_data = Scaler.standardize_data(data)
cleaned_text = TextCleaner.clean_text("example text")
Testing
You can run the unit tests to ensure the proper functioning of the library:
python -m unittest test_data_preprocessing.py
