- Your hands freeze the moment you step outside the examples.
- You forget it quickly because you don't know "why" you're using it.

When studying alone
I clearly followed along exactly, so why isn't it sticking in my head?
The flow of beginners giving up on Python is always similar. Doesn't it look familiar?
Day 1
Memorize the syntax. print, for, if…
Day 3
I can follow along and type it, but I don't know why I'm using it
Day 5
As soon as you step slightly away from the examples, your hands stop moving
Week 1
“I guess I don't have a brain for coding”... and quitting 😵
Why was it so hard to understand?
The problem wasn't your brain; it was the order of learning.
Most introductory courses teach grammar first, and they teach all of it. However, the "why and when to use it" is actually missing.
문법은 외웠는데
In reality, you have no sense of which situations require using variables or loops.
예제는 따라 했는데
Even with just a small change, it feels overwhelming and you don't know where to start.
용어가 많아서
Data types, indexing, iteration... the terminology blocks you before you can even reach the concepts.
This course does not list every single grammar rule. It starts by establishing the core concepts of why and when to use them.
Before / After
The same 60 minutes, but what you take away is different.
- Understand core concepts through everyday analogies.
- You will know when to use it, allowing for practical application.
- It stays in your head even after 60 minutes.
Learning Order
Start with simple analogies and learn by doing it yourself.
For each concept, we first grasp the "why" through everyday analogies, then confirm the "how" with short examples.
01
프로그래밍이란
A program is something that gives a result when you provide input — we'll start by grasping that big picture.
02
자료형·출력·변수
Understand the types of values and store them in 'boxes.'
03
배열·반복문
Collect values in a ‘chest of drawers’ and automatically repeat the same task.
04
조건문
Create different paths for each situation using 'if ~ then'.
05
함수
Bundle repetitive tasks like a 'microwave' and handle them with a single button.
06
복습
We will organize and connect these six concepts all at once, explaining why they were created.
Have you ever
Has this ever happened to you?
You've definitely learned Python, but are you unsure why you're using it?
Does your hand stop as soon as you move beyond the examples?
Concept Preview
Core concepts at a glance through metaphors.
Variables, loops, conditionals, and functions — we show you not just the code, but the "why" behind each concept through illustrations (metaphors).
변수
"I've written the store name in various places, and if I want to change it, I have to find them all."
If you change just one box, everything changes., mọi thứ sẽ thay đổi theo.
반복문
"30 menu items, one line at a time... the lines increase every time one is added."
Write it once and repeat it all. và lặp lại tất cả.
조건문
"We need to show it differently for each situation, depending on whether we are open or not."
Split the path using If ~ then.
함수
"I'm repeating the same age verification process for every customer."
Just press a button and you're done, just like a microwave.

Recommended Audience
For those tired of grammar books, start here.
Who this is for
- Those who are new to coding and feel overwhelmed about where to start
- Those who closed other Python lectures because they were boring
- Office workers who want to grasp only the core concepts in a short amount of time
- Those who want to understand even the "why" and "when" to use it
Those who need to align expectations
- Those who are already working on practical projects using Python
- Those who want to dive deeper into specific fields such as web or data
- Those who want to go through every single grammar point without missing anything.
Requirements
All you need is one thing: a desire to learn.
01
No prior knowledge is required. It is perfectly fine even if you are new to coding.
02
All you need is a computer with internet access. We will go through the installation process together in the lecture.
03
Above all, a lighthearted "let's give it a try" attitude is all you need.
What you will be able to do after taking the course
By the end of the course, these four things will become clear.
Even when encountering code for the first time, you will be able to read and understand "what it means" without getting stuck.
You can explain in your own words why and when to use each concept.
You can judge for yourself what to search for when you get stuck.
You can confidently move on to the next level of courses, such as web or data analysis.

FAQ
Expand and check only the parts you are curious about.
코딩이 처음인데 따라갈 수 있나요?
Yes. Even if you have no prior knowledge at all, every concept is explained through everyday analogies. We don't start by pushing difficult terminology onto you.
왜 60분인가요? 너무 짧지 않나요?
This is because it doesn't just list all the grammar rules. It selects only the core concepts essential for beginners and condenses them around "why and when to use them." It's short, but the takeaway is different.
다른 파이썬 강의와 뭐가 다른가요?
It focuses on understanding rather than memorizing grammar. With 10% theory and 90% application, it helps you first grasp the concept of "Ah, so this is why we use it."
수강 후에는 무엇을 하면 되나요?
Once you grasp the core concepts, you will be able to transition much more easily to courses in your desired fields, such as web development or data analysis.
무료인가요?
Yes, this is an introductory course provided for free.
In 60 minutes, you will realize that Python is not difficult.
Most coding concepts were created to resolve specific "inconveniences." Once you understand those inconveniences and the analogies behind them, the syntax follows naturally. By learning why and when to use variables, loops, conditionals, and functions, you will gain the ability to progress to the next stage of learning on your own.
Clean and tidy
I hope all beginners who want to start Python will watch this lecture. It feels like you are teaching the alphabet before learning English. Thank you.
You explain only the key points without giving me a dull moment, so I understand quickly!
Among the several basic Python lectures I've seen, this was one that explained only the necessary concepts in an easy and concise manner. I especially liked how it explained in a very simple way why this grammar was used and how to do it. (I think it was an excellent choice to explain Python knowledge using Naver's store information. It was a method that could be understood quickly and simply. If there was one thing I wish there had been, it would have been good if there had been one or two practical exercises. Overall, even though it was a free lecture, the message was conveyed well, so I didn't feel like my time was wasted. Thank you for the great lecture!
This was my first time learning Python, so I took this course to get familiar with Python before taking the coding test course! The 60-minute course only covers essential content, so I was able to learn the core concepts of Python well. Thank you:)
