Ejiod:

I will answer your questions:
For the 1st question: Still hold on to your Scrapy tool even if you are doing BeautifulSoup
For the 2nd: I can’t be specific though. 4-5years ago there was a spike in Tech jobs especially once you are good with JavaScript. Then NodeJs and Angular were cute. ReactJs came to light but wasn’t fully functional. Web development role was the fastest way to land a job then. I did a lot of individual projects before applying for web role. Even up till today I get some full stack dev role that I never applied which I always decline cos I’m into DATA.
Would I say it’s chance? Maybe or maybe not.
Your CV/Resume matters. Some don’t mention their portfolio on their CV and expect to be called. While my 1st role as developer I still took nights to learn Python and data stuffs with all seriousness. I’m certain once you are done schooling and by then you build your portfolio getting an offer won’t be an issue.
I was versatile. Even to the point I learnt Automated Software testing and my chances of being called was like 70%. See, one thing I advise is when you get to any position.. don’t ever feel comfortable cos success can sometimes be a bitch that makes you not to climb the tallest building.
For Number 3: Yes Excel is powerful and I bet some that call themselves data scientist can’t do simple or complex computation on excel.
So add Excel to your arsenal.


You are generous. There's no way you won't be blessed. You motivated me to this level I am in data science having bagged a first class degree in the same field as yours(Biochemistry). I'm highly spirited now, cos if someone with same background as mine can do this,then I have no excuse. THANK YOU SIR EJIOD. GOD BLESS YOU

1. For quick analysis.
2. Referencing. I suggest you add XLOOKUP & XMATCH to your arsenals
3.Communicating with your lower team. You send the excel spreadsheet
4. Your boss may be interested in only the information based on the excel and not python
5. Quick charts.
6. Infact learn Google sheet as well.
7. Financial modeling for those on accounting
8. Conditional formatting
9. Split text column. Try go deep on data validations then you understand.
10. There are so many things you can do on Excel but not with pandas.

A typical person like me daily
1. Tableau
2. SQL
3. Excel
4. Google sheet
5. PowerPoint because you must present at least a month
6. Jupyter notebook
7. Rapid miner


Hope I answered your question.

Big man. Is it safe for one to rather use Rapid Miner for predictions rather than learning Sk-learn library in Python?

Just like people use Tableau/Power-Bi instead of the Matplotlib Library?

Modified: I'm asking anybody who can help with an answer too.

Lol bro. E no hard like that. Time and effort make the difference. There's a chapter on ATBS specifically focused on web scraping. Maybe you've not read it yet.
Lol yea. I dropped ATBS and moved to another book when I was having issues with functions. I'll go back to ATBS when I'm done with the new book.

For DAX Expression exercises in Power bi, check wiseowl . co . uk, w3resource . com, kaggle .com.
For exercises without DAX Expression, you can use same sites...
Basically, what can be done in Tableau can be done in power bi...so if you try out any tableau project, you can replicate too in power bi...
If you are on twitter, you can search for #makeovermonday....every sunday, a dataset is dropped and we submit our analysis in Tableau on monday or latest by Wednesday....Its a chance to improve yourself
GL cool

Bro! Your head dey there abeg. Please can you drop a site where I can get exercises in csv to download for excel? And please want to ask if you can put me through on how to move excel files into mysql to finish work on them? Please man. Sql is really crazy, loving it so far

I love wiseowl.co....as regard the makeover Monday, can't the analysis be submitted with POWERBI?

Nope..you cant..
Bcz it's organized by Tableau Developers...
Interestingly, they are working on a way python codes can be used in tableau as a calculated field... shocked
But as usual, you can do it as a personal project on Power Bi using their dataset.

I'll say you should have an idea about both..
Most organisations dont really specify which software or library to use,.The main point is that your presentation should be simple and easy to understand..
We all learn Tableau, PowerBi , excel, matplotlib, seaborn not like we need all for one project but each of them have their own strengths and weaknesses moving forward...

So basically, the point is have an idea of all..whichever suits a project you are working on, you use it..

1) kaggle . com...there are millions of dataset there...or if you are still learning, i advice you check out w3resource . com, bcz they drop solution to the exercises in case you are stuck somewhere..
2) We all love MySql bro....but only after you'v mastered it...I dont think you can move excel file into MySql...i tried that when i was learning back then but it didn't work...What you can do is to duplicate the excel file and change the extension to .sql and try importing the file....If it doesnt work, i suggest yoi google it.....This is one of the major advantage Pandas have over MySql..

Seems you are yet to understand the power of Tableau and PowerBI.
Tableau being the king of Data visualization was and is so powerful that SalesForce acquired it for $15.7Billion. Only place matplotlib comes ahead is animation chart of which Tableau just released this year and they are already building ontop of it.

Even Excel can annotate not talk of Tableau or PowerBI or Google Data studio or Qlik

Please learn and implement with python so you get the underlying principles behind ML. Once you are firm just do RapidMiner or Even Orange3.

Create a table in MYSQL, bearing the name of the columns in the excel file. Then right click on the table created (icon on your left) and import the csv/xlsx file to MYSQL. This should work. Although i do this with POSTGRESQL

Been following your topic for a while now. I can reasonably call myself a data scientist but I must confess that you are making big waves. I've been in programming world generally for a while but I never heightened my game not until recently, thanks to Corona virus.

I've read your every single update and I know plus I've earnt most of the tools you've mentioned so far. I started off with web development packages and I can categorically say I'm a developer considerably.

I started learning data science early this year but was slow with it because I'm an engineering student at my final year, project and fighting to maintain my 4 pointer. But the recent pandemic affords me enough time, so all I do now is learning one thing or the other.

I raise my eyebrow whenever I see you mentioning and emphasising that one needs to know excel for free-following ML life, I do this because I'm yet to be convinced as to its importance. I will love it if you can stress out its indispensable value that makes it one of the tools one needs for data science (especially ML).

Then on web scrapping, I crawl sites with every tool suitable for it but scrapy. I know scrapy is an advanced module created for web scrapping, but I want to ask if it is so important to add to the tools used for web scrapping, I've scrapped a lot of sites without scrapy.

Finally [this is personal to me], like I've said that I've been around for a while, though I'm not in a rush to start earning before learning, I ride on with the faith that one day will be one day for me. But your stories here and many more I've read about young techies make me wonder if I'm doing things differently because I've been all alone in my programming world. You mentioned how you got a firm that hired you shortly after you start your programming journey, I must tell you this has greatly helped in your development. My question is, how did you manage to get those interviews and even the jobs in a very short period? May be it's due to the connections you've had or you are just in the right environment. Please I need you to answer this particular question even if you decline to answer others I've asked before. Thanks.
I don't know why you guys like to compare beautifulSoup with scrapy. They are not comparable. Scrapy is a framework, comparing it with beautifulSoup is like comparing Django and Jinja ,that's if you know what that means.
All am saying is that you should learn scrapy if you want to do serious and systematic scraping

Hi guys, I did further digging on the dataset that cochtrane scraped using a business intelligence tool called Power BI.
Note: The analysis is for the date when the thread made it to front page, not when it was created which spanned from 3rd of June 2019 to 2nd of June 2020 . The data has 28,516 threads from 38 different sections by 5025 different accounts.

Few insights from the dataset
-dre11 is the king of political threads with 361 threads followed by Islie(329) and ijustdey(225) during the time captured. Lala is more interested in celebrity threads compared to politics, followed by Alex. Ogbiwa is the defending champion of sports threads.
-Threads are mostly pushed to front page in the morning, which is reasonable since that is when the day begins.
-There was spike in threads that were pushed to front page in July 2019, but I can't tell if that is the norm during that period since we don't have previous year's data to make the comparison.
-You will think that threads in religion section should top the threads that make it to front page on Sundays, but it came third after politics and celebrity threads.
-853 threads made it to front page with "kill" keyword. That is worrisome and a cause of concern.
e.tc.
Lots of insight can be derived from the data.
Below is a link to the report. It is interactive, so feel free to play around with it.

The advent of coronavirus in March increased the number of posts hitting front page from health section as seen in the image attached below. 1,617 threads on coronavirus have made it to front page.

Instead of having the months start from January to December which might be confusing, I rearranged the months to show when the the data started from, which was June 2019. There has been a huge decline in the number of posts that made it to front page since December 2019 which slightly increased by 17% in March 2020 due to Covid.

The questions that needs to be answered are:
- was there a change in NL policy regarding the number of posts that hits front page?
- or the change in moderators during that period?

Thanks man for your swift response as usual. 1) at kaggle and w3 resource I will try visiting them. Hopefully, I would be able to download the csvs from there. Thanks. 2) but that's rather poor from mysql, it would have been great if they had incorporated that feature into it. I think the best bet for me then is creating tables in mysql and then moving it out to excel to do some quick analysis and then from there, panda(when I eventually start on panda). Thanks again. I am grateful.
