I am very grateful that I can take this level of class at this cost. The fact that you explain it in very easy terms instead of using academic language, and that you continuously motivate and praise beginners who are prone to giving up, were especially helpful. As a liberal arts student, I wanted to understand IT in general before starting to code, so I read a book called 'IT Core Technology Anyone Can Read Quickly and Understand', and since it was a lecture by that author, it was a lecture that I was personally more immersed in.
Oh, I am so glad that you have read my book. Also, I am so happy and grateful that you have mentioned the advantages in such detail. I will continue to work hard to create better lectures and content. Thank you again.
Today, I'm finally getting around to writing a review.
I'm in my mid-30s and I have absolutely no knowledge of computer programming.
I'm currently working at an online shopping mall, and while working, I thought that there's so much information online that it would be nice to collect it and derive the data needed for sales. And on top of that, automation? I started studying crawling and Python with the idea of doing this kind of work in practice to reduce my workload.
These days, it seems like a lot of people are using data for stocks and real estate, and financial investment is a bonus. ㅋㅋ I started with a mixed mind.
I really didn't know anything when I started, but I heard that I need Python to do this, so I took various lectures, and wow, I got stuck even installing the program. ㅋㅋ I'm really a total beginner... I installed it, but I got an error.
Would it have been better if I had started in my 20s? I wanted to ㅠㅠ I felt so ignorant because I struggled with the installation ㅋㅋ Anyway, I was really worried
After much twists and turns, I finally installed it by Googling... I finally started, but I couldn't do it the same way even though I listened to the lecture and followed it. I don't know why this is. I Googled the method and read it, but I wondered what it meant.
So I thought, "Okay, let's really start from the basics. Since I'm already doing it, I should take the introductory lecture?" and signed up.
The lectures I've taken before were the type that gave me the information I needed right away, so I couldn't do it. ㅠㅠ
A baby can't just jump right away ㅋㅋ I was too greedy
While learning crawling, I also learned for the first time that the website code changes so often.
And that's the structure? Anyway, it was really good because it covered the basics of general knowledge.
I learned very simple HTML while working, so this class taught me the basics of HTML, which helped me understand it a lot and helped me a lot with my work. I think this was an unexpected side effect.
The lecture itself is really friendly, and it starts from the very basics, and I think it is a lecture that helps you learn on your own. I had a lot of questions about why the code is applied this way. The teacher's lecture has such a good solution, so I paused the lecture for a while and tried to understand it myself, and watched the lecture again to learn it. Solving the problems also helped me understand a lot.
While listening to this lecture, I learned general knowledge about crawling and the web, and I think I got a sense of what you find and do when crawling, so I signed up for the next lecture to learn more in-depth content. I hope that one day, when I see a website, I can quickly understand its structure and crawl it quickly.
I was raising a child, so I didn't have time, so I woke up at dawn and listened to the lecture, but the lecture was informative, so I think my efforts were not in vain. Please continue to give me good lectures in the future!
Wow~!! This is real recognition~ You showed that you study on your own. It's easy to give up when things are difficult, but it's amazing that you're exploring on your own~ You can achieve anything!! Thank you sincerely ^^
It doesn't just teach grammar, but it applies the content step by step, making it easy to understand and practical. It's good that there's encouragement in the middle of the lecture. There's a lot of content and a lot of examples, so I don't regret the money. It's a great lecture, and I'm looking forward to other videos.
This lecture is for beginners, and many beginners have a hard time understanding IT programming, so I was a little worried about the course review because the satisfaction level may be low.
I am so glad and grateful that you described the advantages in detail and even said that it is a great lecture. I plan to continue to make better lectures in the future, and I will work hard to make even better lectures.
Thank you.
I am leaving a review after completing the course.
The reason I, a typical liberal arts student, started learning Python and crawling was, in fact, when I happened to see the previous lecture by the instructor of Life Coding.
It was relatively satisfactory, but I felt that it was a lecture that I wished the explanations were more detailed from a beginner's perspective. (However, it was free and interesting.)
Furthermore, I wanted to do it properly, so
I took a data science course at a boot camp.
However,
I felt a lot of disappointment with the explanations of the data scientist who was the instructor at the time, and the boot camp learning method (only teaching very basic content, giving assignments, and using search to solve them within the deadline) did not suit me.
(The submission deadline felt too short for a beginner, the method of just studying on your own, etc.)
So I lost interest for a while and wandered around. 'I was studying naturally because I was having fun, but why is it so hard and frustrating now? Is this not right?'
I was suffering from these thoughts.
Then, I decided to try again with the free class method of daily life coding (taking online classes + hands-on practice), so I previewed several lectures, and by chance, I also happened to listen to Janjaemi Coding's lecture.
If I were to define Janjaemi Coding's lecture in one sentence,
I would say it is "differentiated teaching ability".
Since I have previously taken other instructors' lectures,
I could feel that Janjaemi Coding's teaching ability was relatively superior. (This means that if you listen to Mr. Janjaemi Coding's lecture right away instead of wandering around like me, you might not feel its true value.)
If you are the type that doesn't get satisfied unless you do everything from A to Z,
I don't think I would recommend this lecture.
(At least if you are reading this lecture review, you probably are not that type.)
However, if you are interested in improving your learning efficiency by appropriately utilizing the 'lecture' tool',
I would like to recommend this lecture.
From a beginner's perspective, there are often times when you don't understand even the most trivial parts.
In my personal opinion,
at least in this lecture, such difficulties have been reduced by more than 80% compared to other lectures.
The explanations are detailed. For example, even if you simply explain the for loop, in "for item in listdata:",
you explain what item means, what listdata means, and
what the relationship between listdata and item is.
More than anything, for beginners, you explain in detail and to a level that is sufficiently understandable even the most trivial things, such as the last ':' of the for loop,
or why you have to use 'Tab' in the next sentence.
(Of course, I think that the learner's effort to understand by writing all the codes in the lecture one by one is essential.)
I recommend Janjaemi Coding's lecture,
but unfortunately, I also had many difficulties while taking the lecture.
In particular, I am trying to crawl other sites based on what I learned,
but it doesn't work well and I keep getting the "NoneType has no attribute 'get_text()':" error. So, I'm planning to take the data analysis first step (Pandas, plotly) and crawling intermediate (sellenium&scrapy) courses of the already paid teacher, Janjaemi Coding.
I wrote a long post, but I'm not sure if anyone will read it.
I wanted to express my gratitude to the instructor while completing the course.
Thank you.
(And I hope you'll do well in other courses in the future)
Thank you for taking the time to write such a detailed review.
I tried to explain in the way I learn, based on my experience of teaching beginners for 6 years and my own experience of starting from a non-major and always learning new technologies. I am so glad that you explained the parts that are different from other lectures and that it was helpful. Thank you.
The last error part is, for example, when you get data corresponding to a div tag with the following code (i.e., when you specify it as a CSS selector),
data = res.select_one('div')
If there is no data corresponding to the CSS selector (i.e., the data specified as a div tag),
the data variable value becomes None (nothing).
In this state, if you call data.get_text() (writing it this way means calling the get_text() function/method in data), the get_text() in it will not be called because the data itself is empty. So, the error you mentioned, NoneType has no attribute 'get_text()' occurred.
If you think about this explanation carefully, you will understand that the error in English above has a similar meaning. As a result, you will understand that the error occurred because you chose the wrong CSS selector.
If you learn these parts in the following lectures and watch the lectures again, you will understand them more each time you repeat them.
Now that you are out of the beginner stage, for the next level, when you get this error, copy the error, paste it into a Google site, and search for related issues. Then, you will be able to understand the solutions and what various errors mean a little more.
Thank you.
This course is particularly strong in that it provides Spartan practice as if you were learning offline. So when learning input/output functions, data types, control statements, loops, etc., it doesn't just let you understand the grammar and move on, but it allows you to adapt to the language through practice. You can adapt to a language through practice. I recommend it to everyone who is starting out with Python.
Oh, I missed the course review. That's right. I think you need a lot of practice, especially at first. I've designed it so you can do this kind of practice. Thank you.
