# Patatas
[https://pypi.org/project/patatas/](https://pypi.org/project/patatas/)
Patatas is a Python package that provides tools for preprocessing and modeling data using machine learning algorithms.
## Installation
You can install Patatas using pip:
pip install patatas
## Installation
### Usage
Encoding categorical columns
To encode all categorical (object) columns of a pandas DataFrame using Label Encoding, you can use the fritas() function:
```bash
from patatas import fritas
import pandas as pd
# Create a sample DataFrame with categorical columns
df = pd.DataFrame({'Color': ['Red', 'Green', 'Blue'], 'Size': ['Small', 'Medium', 'Large']})
# Encode categorical columns using Label Encoding
df_encoded = fritas(df)
# Show the encoded DataFrame
print(df_encoded)
```
Finding the best value of k for K-NN regression
To find the best value of k (number of neighbors) for K-NN regression based on the mean squared error, you can use the bravas() function:
```bash
from patatas import bravas
import pandas as pd
# Load a sample dataset
df = pd.read_csv('my_dataset.csv')
# Find the best value of k for K-NN regression
best_k = bravas(df, 'target_column')
print(f'The best value of k is {best_k}')
