Data Science: Where to Start?

With technology changing so quickly, are you at a loss as to what to learn first?
It starts with knowing how to collect and handle data.
That's where web crawling comes in.

Hello, this is Mr. Cho.

Hello everyone. I am a business person.
I am a current technical instructor providing professional IT training.

This is the question I hear most frequently in the educational field.
“There’s so much technology these days. What on earth should I study?”

A myriad of technologies, frameworks, and trends coming out every day...
Should we all follow?

There is no need for that.
The key is The point is, 'You don't need to know everything, but you need to understand the basics.'

If you understand the flow and principles of technology,
New technologies are not something to be feared,
It becomes a tool to stimulate curiosity.

And the first step is,
Understanding and working with data starts in this course.

Key strengths of this course 1.

This is not a course to learn flashy techniques for a short time. It is a course to deeply study the overall basic contents that form the basis of those flashy techniques.

Key strengths of this course 2.

Taught by a current technical instructor who has been giving corporate lectures to practitioners. Experience the teaching skills acquired over 10 years.

Learn about these things

① Core Python grammar for data

To collect data from the web, you need to have some understanding of the structure of the web. As a representative example, I will introduce only the key points of dictionaries and data frames that can help you understand the hierarchical structure.

② Create various web crawlers yourself

We will introduce you to a crawler that you can actually use, and how to apply it step by step. You will be able to draw an overall picture of the process and approach to creating a crawler.

③ Ability to solve problems that may arise during crawling

You will encounter various error situations while crawling. Develop the ability to create a more robust and perfect crawler by creating and solving the most frequent error situations yourself.

Things to note before taking the class

Practice environment

  • Operating System and Version (OS): All OS are supported, including Windows, macOS, and Linux.

  • Tools used: Anaconda Jupyter Notebook (you can use other IDEs if needed)

  • PC specifications: 8GB RAM or more recommended

Learning Materials

  • All code files written in class are provided as .html files.

  • Everything else besides the code comes with each video.

Player Knowledge and Notes

  • This course is suitable for beginners.

  • After taking this course, there are data analysis and machine learning classes where you can learn step by step.

Do you have any questions?

Q) Can I follow along even if I don't know much about Python?

Yes, no matter how easy the grammar is, I always explain it.
If you still don't understand, feel free to ask questions.
Our talented tutors, along with our instructors, will answer your questions in near real time.

Q) So, do we only learn content that is too easy?

No. The purpose of this lecture is to melt the 10 years of lectures into a compact and essential explanation for those of you who are busy. I did my best to make sure that not a single second of time is wasted.

Q) Can I get feedback on questions I have during the course?

Yes, in addition to this instructor, there will be tutors. Many skilled tutors will answer your questions from time to time.

Who is this course right for?

  • First-time data beginner

  • A practitioner seeking the essence of data collection over analysis.

  • Wanting to build basic fitness before trendy styles.

  • For those who want to understand the starting point of the data pipeline before cloud AI training.

Need to know before starting?

  • Knowing basic Python syntax is OK! (Not required)

  • A basic understanding of HTML's structure (tags, classes, IDs) will make it easier to follow.

  • All processes are hands-on, reviewing code and results (Beginners welcome!).

      IT 비전공자 입장에서 강력 추천합니다. IT 전공도 아니고 파이썬은 이름만 들어본 정도였는데, 정말 하나하나 친절하게 알려주셔서 수업 따라가는 데 전혀 무리가 없었어요. 강사님 설명이 진짜 ‘왜 이걸 배우는지’를 중심으로 설명해 주셔서 막연했던 웹 크롤링이라는 주제가 훨씬 구체적으로 다가왔습니다. 혼자였다면 시작도 못 했을 것 같은데, 이 강의 덕분에 데이터 사이언스에 자신감이 생겼어요! 소개에서는 시리즈로 다음 강의를 출시한다고 들었는데, 그건 언제쯤 들을 수 있을까요? 이 강의와 연계되는 건가요?

        안녕하세요, db7536님. 소중한 수강평 감사합니다. 말씀하신 대로 시리즈로 다음 강좌(데이터 분석, 머신러닝)가 예정되어 있으며, 다음 달인 7월과 8월에 순차적으로 업데이트할 예정입니다. 관심 가져주셔서 감사합니다.
