pristinizer 0.1.0

Automatic data cleaning, EDA, and missing data visualization for pandas DataFrames

Pristinizer

Pristinizer is a lightweight Python package for automatic data cleaning, exploratory data analysis (EDA), and missing data visualization for pandas DataFrames.

It helps data scientists and ML engineers quickly clean and understand datasets with minimal effort.

Features

• Automatic data cleaning

  • Removes duplicate rows
  • Standardizes column names
  • Handles missing values
  • Removes empty rows and columns

• Dataset summary (EDA)

  • Column data types
  • Missing value counts and percentages
  • Unique value counts

• Missing data visualization

  • Missing value matrix
  • Missing value heatmap
  • Missing value bar chart

• Simple and easy-to-use API

Installation

From PyPI (recommended)

pip install pristinizer

From Source

git clone https://github.com/harmanbajwa2954/Pristinizer-pyProject.git
cd pristinizer
pip install .

Quick Start

import pandas as pd
import pristinizer as ps

# Load dataset
df = pd.read_csv("data.csv")

# Clean dataset
clean_df = ps.clean(df)

# Generate summary
summary = ps.summarize(df)
print(summary)

# Visualize missing data
ps.missing_matrix(df)
ps.missing_heatmap(df)
ps.missing_bar(df)

Examples

Input DataSet

Name	Age	Salary	City
A	25	50000	Delhi
B	NaN	60000	Mumbai
C	30	NaN	NaN

Output

column	datatype	missing_count	missing_%	unique_count
Age	float64	1	33.33	2
Salary	float64	1	33.33	2
City	object	1	33.33	2
Name	object	0	0.00	3

Available Functions
