Quick Start

DataFrame Cleaning

from winiutils.src.data.dataframe.cleaning import CleaningDF
import polars as pl

class UserDataCleaner(CleaningDF):
    """Clean and standardize user data."""

    USER_ID = "user_id"
    EMAIL = "email"
    SCORE = "score"

    @classmethod
    def get_rename_map(cls):
        return {cls.USER_ID: "UserId", cls.EMAIL: "Email", cls.SCORE: "Score"}

    @classmethod
    def get_col_dtype_map(cls):
        return {
            cls.USER_ID: pl.Int64, cls.EMAIL: pl.Utf8, cls.SCORE: pl.Float64
        }

    # ... implement other abstract methods

# Usage
cleaned = UserDataCleaner(raw_dataframe)
result = cleaned.df

Concurrent Processing

from winiutils.src.iterating.concurrent.multiprocessing import multiprocess_loop
from winiutils.src.iterating.concurrent.multithreading import multithread_loop

# CPU-bound tasks (multiprocessing)
def process_chunk(data, config):
    return heavy_computation(data, config)

results = multiprocess_loop(
    process_function=process_chunk,
    process_args=[(chunk,) for chunk in data_chunks],
    process_args_static=(config,),
    process_args_len=len(data_chunks),
)

# I/O-bound tasks (multithreading)
def fetch_url(url, headers):
    return requests.get(url, headers=headers)

results = multithread_loop(
    process_function=fetch_url,
    process_args=[(url,) for url in urls],
    process_args_static=(headers,),
    process_args_len=len(urls),
)

Automatic Method Logging

from winiutils.src.oop.mixins.mixin import ABCLoggingMixin

class MyService(ABCLoggingMixin):
    def process_data(self, data: list) -> dict:
        # Automatically logged with timing
        return {"processed": len(data)}

# Logs: "MyService - Calling process_data with (...) and {...}"
# Logs: "MyService - process_data finished with 0.5 seconds -> returning {...}"

Encryption with Keyring

from winiutils.src.security.keyring import get_or_create_aes_gcm
from winiutils.src.security.cryptography import (
    encrypt_with_aes_gcm, 
    decrypt_with_aes_gcm
)

# Get or create encryption key (stored in OS keyring)
aes_gcm, key = get_or_create_aes_gcm("my_app", "[e-mail]")

# Encrypt and decrypt
encrypted = encrypt_with_aes_gcm(aes_gcm, b"Secret message")
decrypted = decrypt_with_aes_gcm(aes_gcm, encrypted)
