The answer to your question is NO but I will recommend you get the details of the course from Coursera. Thanks

Does that mean after finishing the course, would have to learn those libraries, right?

And could you please send a link to learn them? Thanks.

When you finish learning the course, You will learn the Libraries differently depending on what you plan to do.
Data Analysis
Data Science
Machine Learning
AI
Data Engineering
The needed python libraries will vary.
Check Freecodecamp YouTube Channel, They have everything you need.
I normally recommend you use study materials from different sources and any study material you intend to use, must have dataset you can practice with.

I hope everything is clear to you. I wish you luck in your journey.

Shalom!!!!

What's up guys? I know it's been long since I posted here: been busy with going back to school, work and other stuff.

I remember giving the above advice the last nine months and I'll like to say that as of today, it still stands most especially from my experience working as a data analyst with an NGO while doing my MSc.

I can't emphasize it enough: learn your SQL. Again I repeat, learn your SQL if you are to switch to anything data related: whether a data analyst, scientist or engineer.

Most organizations have databases which you'll use SQL to interact with. I'm saying this because sometimes I feel there's too much emphasis on learning Python. Don't get me wrong; python is important in the world of data but it should be like number 4 on your learning list with spreadsheets and BI tools before it.

In addition to the above, I would advise you work with larger databases when practicing: the table I've been working with had about 120000 rows by 220 columns and it was just one table out of about 300 grin Quite large when you compare it to the ones used on your Udemy tutorial or YouTube or even Kaggle.

I'm not saying this to discourage anyone, just giving you an insider perspective. I would post more tidbits when I have the time.
Hmmmm. Interesting!

Hi Data guys smiley

I want to ask my fellow colleagues in the data field about the need or the use of SQL in their data job.

Honestly, is it that it's not useful?

Basically, I make use of Tools like Excel, Power Bi, Power Query (DAX functions) and Pandas(if need be) for my analysis and Visualization.

I am also proficient with SQL for querying and that is all I know, but it has been of no use since the start of my professional career.

Please is there something I am missing? What do you guys do with SQL? Is it just there for integrating the company data from the software it uses directly to SQL for Querying which is no different from importing the same data to my pandas or Power Query?

Please I really need a detailed answer to this. It will go a long way. I just don't like the feeling of being left out on things like this. Thanks in anticipation.
Re: Chronicle Of A Data Scientist/analyst by Hinokami: 9:40am On Aug 04, 2022
From experience, Excel and power bi couldn't handle a dataset i was working on (4m rows X 50 columns) and that is just one table. It kept crashed and loading till infinity.

Had to import to SQL Server and link to Power BI. I took out a subset of the data though, only the part I needed using sql.

Also it comes in handy when dealing with many tables ie snowflake schema, I found it more easy and enjoyable to join tables to get specific data I needed. It never for once occured to me to use Excel to handle that data because innately I knew I was going to stress myself.

Interesting I must admit. If the issue is loading a Big data like the one you described and then obtaining a subset from the data, then I don't think I still need SQL as Pandas can do that for me.


By the way, can you please tell me how you were able to import such data with SQL because most times I try something like that, it took infinity to load it.

Did you say 4million rows? Omg!

That's even small.

The one I'm working with has 120 million rows by 220 columns and that is just one table.

Most times we use filters (Where) or (Limit) to get the information required.

Real life databases are quite large compared to the ones used on your Udemy/Coursera tutorials.

No matter how many videos, courses, bootcamps or certifications you've done, your best resource as an analyst is always Google/YouTube.

This is because you'll always come across challenges that'll make you question your skillset: those two tools will always come in handy to answer your questions.

Currently researching how to transpose a large dataset. Of course I know how the transpose function works but have never used it on a larger scale.

Your concern with Pandas is effieciency and speed.

SQL server has an import tool.
The data was in a csv file so it was straightforward unless you have the bad luck of having some dirty data you have to clean before it imports correctly.

Hi everyone,

I salute all the great programmers in the house. More knowledge to your brain.

I am new to programming, although I have the zeal since I was very young, I have always wanted to work for Etisalat grin.

I began Python some weeks ago and I think I am done with the basics. But with the many news online and as a Nigerian who want to make at least some cash for upkeep, I feel lost. I kept seeing Python as something that is not gonna bring me some cash any time soon (please don't think I am money oriented, you know there is SAPA everywhere now.)

Please sirs, what is your advice for on the path of programming I should to at least make some money by December?

And please sirs, I need a mentor please for goodness sake.

somebody should just gimme chance and lemme be his mentee pleaseeeeeee

A lot of people keep making the mistake of learning a programming language just for learning sake then try to figure out what to do with the knowledge down the road.

My guy you are still a couple months or years away from making any money with python depending on the path you choose to follow. You can choose between web development (front-end, backend or full stack ) or Data analytics, machine learning and Artificial intelligence.

I always advice people to pick a path and learn what you need. Anything data would take a long time so if you're looking to make some money perhaps as a freelancer as soon as possible you should go for front end web development and then eventually learn both front end and back end to become a full stack developer.

N/B: Most people don't hire entry level backend/fullstack developers so as a newbie I'll say learn front-end and leave python for now because you don't need it for now.

Become a sponge by absorbing all information and knowledge that you can.

Never ever think for once that you know it all.

You can never!

Make Google and YouTube your best friend.

They are your best resources when you meet roadblocks and for research.

It's a lifelong learning process.

With your PC specs, you might be able to run SQL, Python and Spreadsheets easily.

However, BI tools like PowerBI and Tableau might not smoothly.

My PowerBI does hang sometimes on my P.C and the RAM is 8gb.
