I think it's good because the explanation is easy to understand even for non-majors. Personally, I don't like overly long and verbose explanations, but I like that the lecture is concise and focuses on only the parts that can be applied immediately in the field.

I was worried that it would be difficult since I am not a major and have never used a program before, but it was explained so easily and step by step that I understood it all! The lectures are not too long and the content is concise, so it was good to watch them from time to time :) Thank you for the great lecture and I look forward to the new lecture!!

It's very easy and slow to follow, so even a beginner like me can follow along!! I started learning Python because I had to, but the content in Hankang is not too much, and it's good because it explains each topic in detail. I'm a semiconductor practitioner, and if I use this well, it will be very useful in my work. I recommend it to practitioners!

What you will gain after the course

◆ Recommended for these people ◆

◆ Characteristics of this course ◆

Stop with the encyclopedia-like lectures! A reference book-style lecture containing only the core content!

◆ What you will learn ◆

Part 1. From Pandas Basics to Practice for Handling Structured Data

We cover everything from the basics of Pandas, the go-to library for handling structured data in Python, to essential methods and tips for practical application.

Part 2. From the Basics to the Practice of Python Visualization

We cover everything from Python's representative data visualization libraries, Matplotlib and Seaborn, to the more modern Plotly library.

You will learn practical data-visualization methods and tips for drawing simple and clean graphs.

Part 3. Creating Streamlit Web Dashboards Without Basic Web Knowledge

You will learn the basics of the Streamlit library, which allows you to easily create web dashboards without any prior knowledge of web development.

We will conduct a hands-on session where you will create a simple web dashboard using real-world datasets and gain insights from the data.

Hello! This is Park's Data Lab.

◆ I am currently working in process design and defect analysis based on big data analysis at a well-known major corporation. I serve as an internal Data Science instructor and have a deep interest in Python task automation and data science, notably being selected as one of 23 finalists out of over 2,000 candidates for my work in Python-based efficiency improvements.

◆ I first started Python to engage in automated stock trading, and although it left a deep wound in my bank account, I realized Python's potential and achieved great results by applying it to work efficiency. Based on this experience, I am conducting various lectures and seminars under the motto, "Let's leave work 5 minutes earlier through work efficiency."

◆ I also went through numerous trials and errors while studying Python from zero base. With the hope that you won't have to experience those same struggles, I have created this lecture by generously including frequently used methods and essential tips.

You don't need to learn every single detail of Python grammar.

◆ Things potential students might be curious about! ◆

Q. Why should I learn Python? How good is Python for data analysis?

Excel is a representative data analysis app widely used by the general public.

Excel is great for simple use, but it is difficult to work with large datasets, and you eventually have to learn VBA to perform automation and advanced analysis.

Python is not just for data analysis; it is also capable of data analysis. Python is fast. You can automate repetitive tasks by writing simple scripts, and you can use numerous libraries for advanced data analysis for free.

You may feel that there is an initial barrier to entry. However, I believe this lecture will help lower that barrier. Once you overcome that first hurdle, I believe you will be able to personally experience the immense potential that Python holds in the field of data analysis.

Q. I'm new to Python. Will I be able to follow the course and apply it in practice without any issues?

I believe it's not that most people are unable to do data analysis, but rather that they have sought out this course to learn how to do it more efficiently.

You've come to the right place. At first, it might feel as daunting as switching from a familiar tricycle to learning how to ride a bicycle, but eventually, you'll find yourself admiring your own ability to skillfully ride that bicycle at speeds much faster than a tricycle ever could!

    It's easy to listen to because the content that is frequently used in data analysis and can be used immediately is divided into subtopics, and it's easy to listen to the necessary parts first. Thank you for the great lecture.
