🐍 Полезные фишки парсинга в Python

1️⃣ Парсинг JSON без лишних усилий

import json

data = '{"name": "Alice", "age": 25}'
parsed = json.loads(data)
print(parsed["name"]) # Alice


2️⃣ HTML/XML-парсинг с BeautifulSoup

from bs4 import BeautifulSoup

html = "<h1>Hello <b>Python</b></h1>"
soup = BeautifulSoup(html, "html.parser")
print(soup.h1.text) # Hello Python


3️⃣ Парсинг аргументов командной строки с argparse

import argparse

parser = argparse.ArgumentParser()
parser.add_argument("--name")
args = parser.parse_args()
print(f"Hello, {args.name}")


4️⃣ Быстрый CSV-парсинг

import csv

with open("data.csv") as f:
reader = csv.DictReader(f)
for row in reader:
print(row["username"], row["score"])


5️⃣ Регулярки для гибкого текста

import re

text = "Email: [email protected]"
match = re.search(r"\w+@\w+\.\w+", text)
print(match.group()) # [email protected]


🔥 Эти трюки помогают парсить JSON, HTML, CSV, аргументы CLI и даже “грязный” текст.
Подойдут как для скриптов, так и для продакшн-кода.

👉 Сохрани, чтобы не забыть!
