📱Programming Foundations: Beyond the Fundamentals

⌨️ Benefits of learning Python Programming

1. Web Development: Python frameworks like Django and Flask are popular for building dynamic websites and web applications.

2. Data Analysis: Python has powerful libraries like Pandas and NumPy for data manipulation and analysis, making it widely used in data science and analytic.

3. Machine Learning: Python's libraries such as TensorFlow, Keras, and Scikit-learn are extensively used for implementing machine learning algorithms and building predictive models.

4. Artificial Intelligence: Python is commonly used in AI development due to its simplicity and extensive libraries for tasks like natural language processing, image recognition, and neural network implementation.

5. Cybersecurity: Python is utilized for tasks such as penetration testing, network scanning, and creating security tools due to its versatility and ease of use.

6. Game Development: Python, along with libraries like Pygame, is used for developing games, prototyping game mechanics, and creating game scripts.

7. Automation: Python's simplicity and versatility make it ideal for automating repetitive tasks, such as scripting, data scraping, and process automation.

⌨️ Automate File Renaming with Python

Tired of renaming files one by one? Let's automate it with Python!

import os

# https://t.me/LearnPython3

directory = 'path/to/your/folder'
prefix = 'image_'

# Iterate over files in the directory
for count, filename in enumerate(os.listdir(directory)):
    new_name = f"{prefix}{count}.png"
    src = f"{directory}/{filename}"
    dst = f"{directory}/{new_name}"
    
    # Rename the file
    os.rename(src, dst)

💡 Save time and avoid repetitive tasks with this simple script!

⌨️ Extract Text from PDFs with Python

Need to extract text from PDF files? Python makes it easy with the PyPDF2 library!

First, install the necessary module:

pip install PyPDF2

Then, use this script:

import PyPDF2

# https://t.me/LearnPython3

pdf_file = 'sample.pdf'
with open(pdf_file, 'rb') as file:
    reader = PyPDF2.PdfFileReader(file)
    text = ''
    for page_num in range(reader.numPages):
        page = reader.getPage(page_num)
        text += page.extractText()

print(text)

Effortlessly convert PDF content into text format for easy manipulation and analysis!

🔐 Hash a Password with Python

Secure your passwords by hashing them with Python and the hashlib library!

First, install the necessary module:

pip install hashlib

Then, use this script:

import hashlib

# https://t.me/LearnPython3

def hash_password(password):
    # Create a new sha256 hash object
    hash_obj = hashlib.sha256()
    # Update the hash object with the bytes of the password
    hash_obj.update(password.encode('utf-8'))
    # Return the hexadecimal representation of the hash
    return hash_obj.hexdigest()

password = 'mypassword'
hashed_password = hash_password(password)
print(hashed_password)

Ensure your passwords are secure by hashing them before storing!
