Python useful list functions: map, filter, find and reduce

Hugo Sandoval — Wed, 15 Sep 2021 23:56:32 +0000

Hello everyone, I made a small recap of these super useful list functions in Python: map, filter, find, reduce.

Let’s start defining our array.

Defining our array of objects
For example, we gonna use some fruits and their price and quantity.

fruits = [
    {
        "name": "Apple",
        "units": 3,
        "price": 0.25
    },
    {
        "name": "Mango",
        "units": 6,
        "price": 0.35
    },
    {
        "name": "Banana",
        "units": 4,
        "price": 0.15
    },
]

The importance of use User Agent to Scraping Data

Hugo Sandoval — Thu, 30 Apr 2020 02:16:16 +0000

Using User Agent isn't a common practice by many scrapers and crawlers developers. But it is important to know that using the correct User Agent can help and make easy the scraping tasks of many websites.

What is a User Agent?

The User Agent is a text string that the client sends through the headers of a request, and serves as an identifier for the type of device, operating system and browser that we are using. This information tells the server that, for example, we are using Google Chrome 80 browser and a computer with Windows 10. And therefore, the server prepares a response intended for that type of device.
