This simple script extracts specific content from a webpage and saves it to a CSV file. With a few tweaks, it could be customized for different websites and data types.

I listed a gig offering custom web scraping scripts on Fiverr and Upwork. Within a week, I got my first few clients, each paying $50-$200 per script. The demand was bigger than I expected.

لتثبيت المكتبات، استخدم:

pip install nltk

def generate_numbers(start, end):
    for i in range(start, end):
        yield i

def filter_even(numbers):
    for num in numbers:
        if num % 2 == 0:
            yield num

def square(numbers):
    for num in numbers:
        yield num ** 2

# Chaining
numbers = generate_numbers(1, 10)
even_numbers = filter_even(numbers)
squared_numbers = square(even_numbers)

print(list(squared_numbers))  # Output: [4, 16, 36, 64]

The yield from statement allows a generator to delegate part of its operations to another generator.

from pydantic import BaseModel

class User(BaseModel):
    id: int
    name: str
    age: int
    is_active: bool = True

In this model, each attribute has a specified type. The is_active attribute also has a default value of True.

Once the virtual environment is activated, you can install packages using pip:

pip install package_name
