python pair plot 

데이터 세트의 숫자 변수 간의 쌍 관계를 보여주는 산점도 그리드입니다. 일반적으로 데이터 분포와 변수 간의 관계를 이해하는 데 사용됩니다.

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

import sklearn
print(sklearn.__version__)

# Sample dataset (Iris dataset)
from sklearn.datasets import load_iris


iris = load_iris()
df = pd.DataFrame(iris.data, columns=iris.feature_names)
df['species'] = [iris.target_names[i] for i in iris.target]

# Create a pair plot
sns.set(style="ticks")
pairplot = sns.pairplot(df, hue="species", diag_kind="kde")

# Save the pair plot as an image
output_file = "pair_plot.png"
pairplot.savefig(output_file)
print(f"Pair plot saved as {output_file}")

# Show the pair plot
plt.show()

[VSCODE] 14 VS Code Extensions Every Data Engineer Should Swear By for Maximum Productivity

1. Jupyter (85M+ downloads)

[python] Generate OTP using python

Here’s how you can generate a one-time password (OTP) using Python:

import random

def generate_otp(length=6):
    """
    Generates a numeric OTP of the given length.
    Default length is 6.
    """
    if length <= 0:
        raise ValueError("Length must be greater than zero")
    otp = ''.join([str(random.randint(0, 9)) for _ in range(length)])
    return otp

# Example usage
otp = generate_otp(6)
print(f"Your OTP is: {otp}")

Your OTP is: 583920

https://pypi.org/project/rich/

Rich is a Python library for rich text and beautiful formatting in the terminal.

The Rich API makes it easy to add color and style to terminal output. Rich can also render pretty tables, progress bars, markdown, syntax highlighted source code, tracebacks, and more — out of the box.

python -m pip install rich

from rich.progress import Progress
import time

def main():
    with Progress() as progress:
        task1 = progress.add_task("[cyan]Downloading...", total=100)
        task2 = progress.add_task("[magenta]Processing...", total=200)

        while not progress.finished:
            time.sleep(0.03)  # Simulate some work
            progress.update(task1, advance=1)
            progress.update(task2, advance=0.5)

if __name__ == "__main__":
    main()

    # Create a progress bar
    with Progress() as progress:

        task = progress.add_task("[cyan]Processing...", total=100)
        
        # Update progress
        for i in range(100):
            time.sleep(0.05)  # Simulate some work
            progress.update(task, advance=1)  # Advance the progress bar by 1
