Python beginner projects from a Python beginner dev

#python #beginners

Hey all,

So, I just started studying Python and I developed some beginner projects that I'd like to share. This way others Python beginner devs can get inspired from them!

1. Dices simulator

This project simulates and prints two random dices.

import random

dices = 2

for i in range(0, dices):
    print(random.randint(1,6))

2. Password generator

This project generates a random 16-length password.

import random

lower = 'abcdefghijklmnopqrstuvwxyz'
upper = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
numbers = '0123456789'
symbols = '[]{}()*;/,_-!@#$%&+='

all = lower + upper + numbers + symbols

length = 16
password = ''.join(random.sample(all, length))
print(password)

3. Youtube audio downloader

This project downloads the audio from a YouTube URL.

Pre-requirement

It's needed to install the youtube_dl:

pip3 install youtube-dl

from youtube_dl import YoutubeDL

audio_downloader = YoutubeDL({'format':'bestaudio'})
audio_downloader.extract_info(input('Enter youtube url :  '))

4. Message encrypt-decrypt

This project encrypts and decrypts a message.

Pre-requirement

It's needed to install the cryptography:

pip3 install cryptography

Encrypt a message

from cryptography.fernet import Fernet

key = b'ntLaRE-8-a81Bqa74aCL6ejFW4hr6ZO9m0fWbDOmys8=' # Some awesome key
message = input('Enter a message: ')

f = Fernet(key)
encrypted = f.encrypt(message.encode())
print(encrypted.decode("utf-8"))

Decrypt a message

from cryptography.fernet import Fernet

key = b'ntLaRE-8-a81Bqa74aCL6ejFW4hr6ZO9m0fWbDOmys8=' # Some awesome key
message = bytes(input('Enter a encrypted message: '), encoding='utf8')

f = Fernet(key)
decrypted = f.decrypt(message)
print(decrypted.decode("utf-8"))
