Ранее я уже упоминал о другой фишке из ˍˍfutureˍˍ , это оператор деления. from __future__ import division Суть проста. Раньше сложность типа данных результата поределялась типом самого сложного операнда. Например: int/int => int int/float => float В первом случае оба операнда int, значит и результат будет int. Во втором float более сложный тип, поэтому результат будет float. Если нам требуется получить дробное значение при делении двух int то приходилось форсированно один из операндов конверировать в float. 12/float(5) => float Но с новой "философией" это не требуется. В Python3 "floor division" заменили на "true division" а старый способ теперь работает через оператор "//". >>> 3/2 1.5 >>> 3//2 1 То есть теперь деление int на int даёт float если результат не целое число. В классах теперь доступны методы __floordiv__() и __truediv__() для определения поведения с этими операторами. Данный переход описан в PEP238. #pep#2to3#basic

#Python#webscraping 😎 Automate the Boring Stuff with Python Programming Automate the Boring Stuff with Python was written for people who want to get up to speed writing small programs that do practical tasks as soon as possible. You don’t need to know sorting algorithms or object-oriented programming, so this course skips all the computer science and concentrates on writing code that gets stuff done. - Web scraping - Parsing PDFs and Excel spreadsheets - Automating the keyboard and mouse - Sending emails and texts - And several other practical topics ⚖️10.5 GB 🔗Link ----- Main channel:@repo_science Coupons: @freecoupons_reposcience -----

#webScraping El #UserAgent, o Agente de Usuario en español, es una cadena de texto que identifica el navegador web o la aplicación que se utiliza para acceder a un sitio web. Esta cadena se envía al servidor web en cada solicitud y puede contener información sobre el sistema operativo, el navegador web, la versión del navegador y los complementos utilizados. La información obtenida también puede utilizarse para optimizar la experiencia del usuario, por ejemplo, sirviendo contenido diseñado para funcionar mejor en un dispositivo móvil en lugar de una computadora portátil. Por otro lado, los webmasters pueden usar la información del user agent para verificar el reconocimiento de bots, para bloquear bots no deseados, o para algo como un análisis cruzado de usuarios o un análisis de la audiencia del sitio web. A continuación les dejamos una listado extenso de users-agents👇 🔗Lista de users-agents ----- Main channel: @repo_science Coupons: @freecoupons_reposcience -----

Use simple CSS/XPath selectors, spiders for big crawls with pause/resume, proxy rotation, and CLI—no code needed sometimes. Install via pip; it's memory-light and beats others in speed. You save time fixing broken scrapers, scrape reliably at scale, cut costs with AI tools, and focus on using data for leads, prices, or research. https://github.com/D4Vinci/Scrapling
