Simple APIs (Part 1)

-

The speaker discusses APIs, specifically focusing on REST APIs, their structure, and how they work. Here's a summary of the key points mentioned:


API Overview:


APIs (Application Programming Interfaces) allow two pieces of software to communicate with each other.

APIs define inputs and outputs for communication between software components.

Users interact with APIs by providing inputs and receiving outputs, similar to using functions.

Pandas API:


Pandas provides a set of software components for data manipulation.

Users utilize the Pandas API to process data by communicating with these components.

When working with Pandas, creating a DataFrame from a dictionary is considered an "instance" in API terminology.

Users communicate with the Pandas API through DataFrame methods like head() and mean().

REST API Overview:


REST APIs (Representational State Transfer) enable communication over the internet, providing access to resources like data storage and AI algorithms.

Clients interact with REST APIs through HTTP requests and responses.

Key components of REST APIs include clients, resources, endpoints, requests, and responses.

HTTP methods (such as GET, POST, PUT, DELETE) are used to transmit data over the internet.

Using REST APIs for Crypto Currency Data:


Crypto currency data is well-suited for use in APIs due to its constant updates and importance in trading.

Py-Coin-Gecko is introduced as a Python client/wrapper for the Coin Gecko API, which provides up-to-date crypto currency data.

Py-Coin-Gecko simplifies the process of collecting data, allowing users to focus on their tasks.

The provided example demonstrates using Py-Coin-Gecko to request crypto currency data (e.g., Bitcoin prices in USD for the past 30 days) and processing the JSON response.

Data Visualization:


After retrieving data, the speaker discusses creating a candlestick plot using Plotly.

The process involves grouping data by date to find minimum, maximum, first, and last prices for each day, and then plotting the candlestick chart using Plotly.

Overall, the video provides an overview of APIs, focusing on both general concepts and their application in retrieving and visualizing crypto currency data using REST APIs like Py-Coin-Gecko.

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...
