REST APIs & HTTP Requests - Part 2

-

 The speaker discusses the HTTP protocol and demonstrates its usage in Python using the Requests library. Here's a breakdown of the main points covered:


Introduction to Requests Library:


The Requests library is a popular method for working with the HTTP protocol in Python.

It provides an easy way to send HTTP/1.1 requests.

GET Requests:


GET requests can be made using the get method of the Requests library.

After sending a GET request, a response object (r) is obtained, containing information about the request, such as the status code.

Request headers and body can be accessed through attributes of the response object.

Response headers, including information like date, content type, and encoding, can be accessed similarly.

The text attribute of the response object provides the HTML content of the response body.

Additional content can be downloaded using other methods provided by the library.

Example: Using GET Requests with httpbin.org:


httpbin.org is used as a simple HTTP Request & Response Service for demonstration.

A GET request is sent to the server, with a query string containing parameter-value pairs.

The query string starts with a question mark ? followed by parameter-value pairs separated by &.

Example Code for GET Request:


Python code demonstrates how to create a query string using a dictionary (payload) and pass it to the params parameter of the get function.

The URL, request body, status code, response text, and content type are printed out.

POST Requests:


POST requests are used to send data to a server, typically in the request body, rather than the URL.

To make a POST request, the post function of the Requests library is used, and the data is passed through the data parameter.

Comparison of GET and POST Requests:


The difference between GET and POST requests is highlighted by comparing their URLs and request bodies.

Overall, the video provides a comprehensive overview of using the Requests library in Python to interact with the HTTP protocol, including both GET and POST requests.

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...
