Solving 100 Python Pandas Problems! (from easy to very difficult)

Solving 100 Python Pandas Problems! (from easy to very difficult)

In this tutorial, you'll gain hands-on experience with the python pandas library, building experience with data manipulation and analysis skills important for data science. You'll learn how to create, modify, and analyze DataFrames, handle missing data (NaNs), clean messy data, and generate some visualizations. By tackling a variety of problems, from basic data handling to advanced DataFrame techniques, you'll build a solid foundation in managing and interpreting real-world data sets using pandas.

Solving Real-World Data Science Problems with LLMs! (Historical Document Analysis)

Solving Real-World Data Science Problems with LLMs! (Historical Document Analysis)

In this video we walk through the process of analyzing historical documents using Python & Large Language Models. We start by setting up LLMs using both closed-source (OpenAI API) and open-source (Llama 2 via Ollama) options. Next, we walk through how we can leverage the LLMs to parse out entities from text. After this we actually start playing around with our data, loading in a specific subcategory of documents from Kaggle and see how we can connect pages from the same documents together. Once this is completed, we repeat the entity parsing process for our actual data to get pieces of information such as names, ages, and locations from our documents. Finally we analyze these entities to learn some insights from our document database.

Python Project: Implement a REST API with Flask & Flasgger Libraries!

Python Project: Implement a REST API with Flask & Flasgger Libraries!

We continue where we left on in the last video and implement two REST endpoints for a book review API. We implement a Get request to retrieve all our reviews and implement a Post request to add a new review to our Airtable database. We use the Flasgger library to create interactive documentation for our endpoints. We use ChatGPT to help us write our endpoints Python code. We use Render.com to deploy our API to a publicly accessible URL Link to first video: https://youtu.be/moi8WPO3Xhs Source code: https://github.com/KeithGalli/python-api-example/tree/part1-code Final source code: https://github.com/KeithGalli/python-api-example/tree/book_review Gitlog command info can be found in this article: https://medium.com/posh-engineering/mastering-the-terminal-to-improve-development-speed-fd234149efb6 How to set environment variables (all operating systems: https://www.twilio.com/blog/how-to-set-environment-variables-html More information on the Flasgger library: https://github.com/flasgger/flasgger Handling API keys with a Python decorator: https://coderwall.com/p/4qickw/require-an-api-key-for-a-route-in-flask-using-only-a-decorator If you enjoyed this video, be sure to give it a like and subscribe :).

How to create & deploy an API in Python! (with interactive documentation)

How to create & deploy an API in Python! (with interactive documentation)

In this video, we work through the process of creating and deploying a Python3 based API using libraries such as Flask, Flask-Restful, & Flasgger. Link to code: https://github.com/KeithGalli/python-api-example Part 2: https://youtu.be/rCrDYRBOuNw?si=bBeT9orOpjr-089S In this first video, we start with the basics, setting up GET endpoints and learning how to deploy our API to the cloud (using Render.com). This part is crucial for understanding the core functions of APIs and making them accessible worldwide. In the second video, we progress to implementing POST requests and constructing a full-fledged Book Review API, similar to services like Goodreads. This involves integrating API functionality to post and retrieve book reviews from a database, with practical examples using Airtable for database interaction. Flasgger plays a crucial role in our tutorial, providing interactive documentation through its SwaggerUI integration. This feature allows you to visualize and interact with your API directly at http://localhost:5000/apidocs, offering a clear and user-friendly overview of your API's capabilities. Additionally, we cover essential practices like working with GitHub repositories, managing Python libraries, and employing Flask and Flask-Restful for API development. The skills in crafting effective GET and POST requests are emphasized, highlighting the importance of efficient system communication. This video is ideal for anyone keen on enhancing their Python programming, API development, and cloud deployment skills. Whether you're a beginner or an experienced developer, this tutorial provides valuable experience in developing well-documented and user-friendly APIs.
