print(f"Her name is {name}. Her email is {email}")
Her name is olivia ringslap.Her email is boatbench@thirty-three-mighty-horses.link
silly.a_thing()
'five cherry onions'
silly.thing()
'container of khaki wads'
silly.things()
'a tote of plans, twenty-four eyes, and eighteen garlic arms'
silly.sentence()
"God himself can't wait to move a hat in Birmingpoop."
silly.paragraph()
"Agustin Neutral-Jerk needs a group of concerns, badly. Agnes Basil can't wait to taste a box of slate chairs in Assesford. To get to Testasia, you need to go to Fantasticheartsound, then drive east. The band 'Queen' will hurl a dance. To get to Arztotzka, you need to go to Cape City Central, then drive north. The world will head to Integrated Eye And Onion to buy a tub of boots. Assemble jean! Seth Violetbag will assemble a laudable ring. Lampton is in South Yemen. Birmingobject is in West Cybertron."
6.3.3. Random User: Generate Random User Data in One Line of Code#

'To cook the rice, bring a large pot of water to boil. Add the rinsed rice and continue boiling for 30 minutes, reducing heat as necessary to prevent overflow. Remove from heat, drain the rice and return the rice to pot. Cover and let the rice rest for 10 minutes or longer, until youāre ready to serve. Just before serving, season the rice to taste with salt and fluff it with a fork.\nTo make the curry, warm a large skillet with deep sides over medium heat. Once itās hot, add the oil. Add the onion and a sprinkle of salt and cook, stirring often, until the onion has softened and is turning translucent, about 5 minutes. Add the ginger and garlic and cook until fragrant, about 30 seconds, while stirring continuously.\nAdd the bell peppers and carrots. Cook until the bell peppers are fork-tender, 3 to 5 more minutes, stirring occasionally. Then add the curry paste and cook, stirring often, for 2 minutes.\nAdd the coconut milk, water, kale and sugar, and stir to combine. Bring the mixture to a simmer over medium heat. Reduce heat as necessary to maintain a gentle simmer and cook until the peppers, carrots and kale have softened to your liking, about 5 to 10 minutes, stirring occasionally.\nRemove the pot from the heat and season with tamari and rice vinegar. Add salt (I added 1/4 teaspoon for optimal flavor), to taste. If the curry needs a little more punch, add 1/2 teaspoon more tamari, or for more acidity, add 1/2 teaspoon more rice vinegar. Divide rice and curry into bowls and garnish with chopped cilantro and a sprinkle of red pepper flakes, if youād like. If you love spicy curries, serve with sriracha or chili garlic sauce on the side.'

6.3.14. Parsera: Natural Language Web Scraping with LLMs#
Show code cell content
!pip install parsera
Show code cell content
!playwright install
Writing and maintaining web scraping code requires constant updates due to changing HTML structures and complex selectors, which results in brittle code and frequent breakages.
With Parsera, you can scrape websites by simply describing what data you want to extract in plain language, letting LLMs handle the complexity of finding the right elements.
Hereās an example that scrapes GitHubās trending Python repositories page to collect:
Repository names
Repository owners
Star counts
Fork counts
import os
os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY_HERE"
from parsera import Parsera
from pprint import pprint
url = "https://github.com/trending/python?since=daily"
elements = {
"Repository": "Name of the repository",
"Owner": "Owner of the repository",
"Stars": "Number of stars",
"Forks": "Number of forks",
}
scraper = Parsera()
result = scraper.run(url=url, elements=elements)
