Optional: HTML for Web Scraping

-

The speaker covers the basics of Hypertext Markup Language (HTML) for web scraping. Here's a summary of the key points discussed:


Understanding HTML:


HTML is used to structure web pages and consists of elements enclosed in angle brackets called tags.

Tags define how content should be displayed on a web page.

HTML Composition:


HTML documents start with a DOCTYPE html declaration, followed by the root html element.

Within the html element, there is typically a head element containing meta information and a body element containing the visible content of the page.

Tags like h3 (heading) and p (paragraph) are used to structure and display content on the page.

Each HTML tag has an opening (start) tag and a closing (end) tag, with content enclosed in between.

Tags may also have attributes, such as the href attribute in an anchor (a) tag.

HTML Trees:


HTML documents can be represented as document trees, with nested tags forming a hierarchy.

Tags may contain other tags and strings, with child, parent, and sibling relationships defined accordingly.

The html tag serves as the root of the tree, with head and body tags as its children.

Tags within the head and body sections are siblings.

HTML Tables:


Tables in HTML are defined using the table, tr (table row), and td (table data/cell) tags.

The first row of the table can be defined with th (table header) tags.

Each td tag represents a cell within a row, with content enclosed within.

Web Scraping:


With a basic understanding of HTML, viewers can extract data from web pages using Python.

Overall, the video provides an introductory overview of HTML, focusing on its structure, composition, tree representation, tables, and their relevance for web scraping.

Notes on Hiring for Data Science Teams

-
  Unicorn Myth in Hiring: Companies often seek individuals with a myriad of skills for data science roles. Ideal candidates possess domain-specific knowledge, excel in data analysis, and have strong presentation and storytelling skills. However, finding such a "unicorn" is rare, and the focus should shift to other essential qualities. Resonance with Company DNA: The key is to identify applicants who resonate with the company's values and business domain. While analytics skills can be taught, passion for the business is intrinsic and contributes significantly to productivity. Curiosity Matters: Curiosity is a top priority in hiring for a data science team. Candidates should demonstrate a broad curiosity, showing interest in various aspects of their surroundings beyond just data science. Sense of Humor: A lighthearted approach is crucial, as being too serious may hinder collaboration and creativity. A sense of humor aids in navigating challenges and fosters a positive work ...

switch functions

-
  Nested IF Function : The  nested IF  function allows you to perform tests with multiple conditions and return different values based on the results of those tests. It is called “nested” because one IF function is embedded inside another IF function. Syntax of a generic nested IF formula: =IF(condition1, result1, IF(condition2, result2, IF(condition3, result3, result4) ) ) Each subsequent IF function is embedded into the  value_if_false  argument of the previous function. SWITCH Function : The  SWITCH  function is a more compact alternative to nested IF statements. It compares an expression against a list of values and returns the result according to the first matching value. Syntax of the SWITCH function: =SWITCH(expression, value1, result1, [default or value2, result2], ... [default or valueN, resultN]) It has four arguments: expression : The value to compare against the list of values. valueN : A value com...
