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}")
Rich is a Python library forrichtext and beautiful formatting in the terminal.
TheRich APImakes 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)

Python을 사용하여 Wi-Fi QR 코드를 생성하려면 qrcode 및 Pillow 라이브러리를 활용할 수 있습니다. Wi-Fi QR 코드의 데이터 형식은 다음과 같습니다:

"""

:param hidden: Whether the network is hidden (True/False)
:param output_file: Name of the output image file
"""
# Format Wi-Fi QR code data
wifi_data = f"WIFI:S:{ssid};T:{encryption};P:{password};H:{'true' if hidden else 'false'};;"

img = qr.make_image(fill_color="black", back_color="white")
