Data Analysis with Python - Full Course for Beginners (Numpy, Pandas, Matplotlib, Seaborn)

Learn Data Analysis with Python in this comprehensive tutorial for beginners, with exercises included!
NOTE: Check description for updated Notebook links.
Data Analysis has been around for a long time, but up until a few years ago, it was practiced using closed, expensive and limited tools like Excel or Tableau. Python, SQL and other open libraries have changed Data Analysis forever.
In this tutorial you'll learn the whole process of Data Analysis: reading data from multiple sources (CSVs, SQL, Excel, etc), processing them using NumPy and Pandas, visualize them using Matplotlib and Seaborn and clean and process it to create reports.
Additionally, we've included a thorough Jupyter Notebook tutorial, and a quick Python reference to refresh your programming skills.

[@vegetossgss1114]

I am 25 and I come from a strong pure and applied mathematical background, but I am a total newbie in programmation. I please have some questions: 1/ Are SQL, Python and R enough to get a permanent position as a Data Analyst / Data Scientist? 2/ How much time do I need to be able to manage and organize databases, and use them to produce statistical analysis and graphs? 3/ If I am hired, can the employer change his / her mind and ask me to code in other languages that were not written in my curriculum, such as C++ or Java?

[@matiasdiaz3808]

​@@vegetossgss1114 I could anwer your questions: I`m working in a data science team. In an entring possition you are generally hired as data analyst in the first place, even thought some business don`t make such diferences between data analyst and data scientists. 1- SQL knowledge is a must. You should be fine opting between R and Python. If you are starting and don`t know neither of them, I would reccomend Python, since it´s the most popular. 2- In most companies they already have data bases and you need to know how to write SQL queries to access the data and, after that, cleaning it with Python or R. If you are just trying things out, you only need data tables from websites such as kaggle. CSV or excel files. 3- It obviously deppends on the company, but that would be odd, since data analys/scientists are not meant to be "professional programmers". If you have a strong mathematical background I think it will be quite easy for you to understand machine learinig algorithms in the future, which is something most people struggle with.

[@SpicyTurkey83]

I have a data science minor (with a Masters in Mech. Engineering). I work as a data scientist with focus on engine systems at the airlines. I'll tell you right now, this course was more informative than all the classes combined that I took in college. Santiago is one of the best you'll get, and also for free. This is truly a wonderful refresher.

[@TONYSTARK-ee5wy]

I want to start this course. Is it still relevant in the end of 2023 or the information shared has become obsolete. Any insight will be highly appreciated brother.

[@SpicyTurkey83]

ABSOLUTELY still relevant. Depending on where you work, you'll likely use Python or R, with occasional Excel uses as well. The important thing is the groundwork that is laid in this course. If you have a chance to take some probability and statistics classes at your school, do that. Also take your math classes seriously. Finally, Take an intro to data class somewhere online (easy to find), and you will likely know everything I know right now. I make about $150K/year so...@@TONYSTARK-ee5wy

Possible error list: Numpy Excercises - Logical operations: Given the X numpy array, return True if any of its elements is zero (prosing a change to non zero here) because np.any() is a test for true (non zero) elements, and therefore the wrong answer.

[@ItachiUchiha-cu2gv]

A word of advice for the guy teaching, please type the commands/codes yourself while explaining each line of code. You are just skimming what was already written and barely giving any time before scrolling down. Writing the code (prepare then read it from another screen or script) and explaining it will have a massive difference for your audience/students to understand. Teachers like blackboards over slideshows/pre-written materials to teach, because it helps the pace to train on it, is almost equal to the pace students understand. Sure, the video gets a bit longer or maybe a lot but nothing beats understanding it better than a quick video where it's harder to understand.

Data analysis is the process of exploring and analyzing large datasets to make predictions and boost data-driven decision-making. Data analytics allows us to collect, clean, and transform data to derive meaningful insights. It helps to answer questions, test hypotheses, or disprove theories. Data analytics is used in most sectors of businesses. Here are some primary areas where data analytics does its magic: Data analytics is used in the banking and e-commerce industries to detect fraudulent transactions. The healthcare sector uses data analytics to improve patient health by detecting diseases before they happen. It is commonly used for cancer detection. Data analytics finds its usage in inventory management to keep track of different items. Logistics companies use data analytics to ensure faster delivery of products by optimizing vehicle routes. Marketing professionals use analytics to reach out to the right customers and perform targeted marketing to increase ROI. Data analytics can be used for city planning, to build smart cities.

Very thorough video, does a great job of explaining intricate concepts in a simple way.

[@BiologyIsHot]

The flow in this needs some work in my opinion. I've been using Pandas/Matplotlib for like a year and I still had a hard time following this. It's normal to hit high-level discussion before diving into specifics, but the way it's done here is not the best example on this channel. Doesn't help that the guy's pace of speech is not great. Slows down at all the wrong parts and rattles off important info.

[@savanrai2489]

Can you reply me because I have some confusion I want to clear it please help me

[@kiet489]

Excel is a good tool however it cannot deal with large data. Image doing all the analysis with even 5000 rows having to draw graph after graph onto different sheet. Excel gets very sluggish. With Python and their libraries with constant updates and support from the community, your good to go with even 1 million rows. Also like he said in the video, it gets cluster and tiring looking at the spreadsheets constantly, I find it quite distracting to do my analysis. SQL is good. I got no comments on that :)

[@moeinghahremani54]

Dear Santiago! Great thanks releasing the valuable video! You have rescued me from confusion in data science

[@stillwrinkled]

This course isn't good. The instructor moves like a bullet train between topics. Fonts are too small for Mac book Air. The section on data cleaning is very confusing. I had to pause this video and follow other videos on data cleaning. The flow of topics is also very jarring. Why isn't data cleaning the second topic after 'Introduction'? I tried my best but gave up after 3 hours or so.

This is more of a video overview with external exercises (linked in the show more section). It seems useful but I'm not sure it works as a KZbin vid. I wish it went through everything in real-time rather than having to do exercises on one's own without any visual feedback.

HI Bro.. to get a complete understanding of this.. do we need to have had learn Python course ( Coding) as a pre requisite..kindly advise..

[@ChangesOfTomorrow]

If this is intended for people with no knowledge of Python, it's hard to follow. I don't get how to write commands or what the basic principles are, so it seems to me by 'beginners' you meant people who know some python and want to dive into data analysis using it.

[@jeremyjoe7494]

A beginner's course to Python is meant for people who are new to Python. Once you want to use Python for a specific goal, there is no reason to repeat the basics of Python since you can learn that in their Python course.

[@eilidhwells6059]

Quite disappointed by the teaching structure. Nothing hands on, just endless narrations, code executions and assumptions. It is far from beginner friendly and seems rushed all the time. Not sure if the comments are legitimate because, I can't be the only one struggling to process and grasp the plenty methods and arguments while the course progresses. Started off well, but completely sunk from Numpys down.

[@abioyeorimadegun7851]

I almost got discouraged by your comment but I decided to follow the video comprehensively The best way I think to understand the tutorial is by practicing the codes available via the links in the description and trying the exercises after every lesson. Although, you might end up spending more than 4 hours on the video but i believe it's a good sacrifice for knowledge. That aside, I agree with you that the tutorial is not 100% beginner friendly. You must have some basic knowledge of Python before even thinking about using Python for Data Analysis. If you don't, it's better to watch a tutorial on general Python programming for beginners before this.

[@AaronDennis1111]

You know, you have to tell us about import requests. This isn't something python beginners automatically know exists. This is a big problem with all these "learn code" courses. You're not walking us through line by line and describing what the code does or when, why, how we should use it. It's great to see what python "can" do, but we need to know when to do what with it. These courses are the equivalent of telling us that numbers exist, giving us 0-9, showing that numbers can be added and such, and then expecting us to go out into the real world and apply them to geometry without ever providing the intermediary steps.
