Course Description

Welcome to the first advanced and project-based Pandas Data Science Course!

This Course starts where many other courses end: You can write some Pandas code but you are still struggling with real-world Projects because

  • Real-World Data is typically not provided in a single or a few text/excel files -> more advanced Data Importing Techniques are required

  • Real-World Data is large, unstructured, nested and unclean -> more advanced Data Manipulation and Data Analysis/Visualization Techniques are required

  • many easy-to-use Pandas methods work best with relatively small and clean Datasets -> real-world Datasets require more General Code (incorporating other Libraries/Modules)

No matter if you need excellent Pandas skills for Data Analysis, Machine Learning or Finance purposes, this is the right Course for you to get your skills to Expert Level! Master your real-world Projects!

This Course covers the full Data Workflow A-Z:

  • Import (complex and nested) Data from JSON files.

  • Import (complex and nested) Data from the Web with Web APIs, JSON and Wrapper Packages.

  • Import (complex and nested) Data from SQL Databases.

  • Store (complex and nested) Data in JSON files.

  • Store (complex and nested) Data in SQL Databases.

  • Work with Pandas and SQL Databases in parallel (getting the best of both worlds).

  • Efficiently import and merge Data from many text/CSV files.

  • Clean large and messy Datasets with more General Code.

  • Clean, handle and flatten nested and stringified Data in DataFrames.

  • Know how to handle and normalize Unicode strings.

  • Merge and Concatenate many Datasets efficiently.

  • Scale and Automate data merging.

  • Explanatory Data Analysis and Data Presentation with advanced Visualization Tools (advanced Matplotlib & Seaborn).

  • Test the Performance Limits of Pandas with advanced Data Aggregations and Grouping.

  • Data Preprocessing and Feature Engineering for Machine Learning with simple Pandas code.

  • Use your Data 1: Train and test Machine Learning Models on preprocessed Data and analyze the results.

  • Use your Data 2: Backtesting and Forward Testing of Investment Strategies (Finance & Investment Stack).

  • Use your Data 3: Index Tracking (Finance & Investment Stack).

  • Use your Data 4: Present your Data with Python in a nicely looking HTML format (Website Quality).

  • and many more...

This course is well-suited for beginners and provides a solid foundation in data exploration using Python pandas. While I appreciated the use of straightforward datasets for learning purposes, I was expecting to work on 12 distinct projects. However, many of the 'projects' were different parts of the analysis of the same dataset. Additionally, I was hoping for more advanced insights, such as comparisons of different methods for completing tasks or discussions about how these concepts apply to real-life projects.

It's a very good, well organized course. After finishing some courses in Data Analytics with Python and learning so much stuff I was left confused. I learned a lot but didn't know what to do with all those information. Well, it's not the case any more. Alexander's method for the projects not just teaches you new methods in Pandas it also gives you a solid understanding of what it's really like working on a project. The road map of Data Analysis. Now, I feel confident to start my own projects. Thank you Alexander for this very professional content!

By Evan Marie Carr on 12/6/2022

From someone who has taken over 30 certified courses, including 2 Harvard courses, in an effort to fast track a new data science life path, Alexander is an AMAZING teacher. There are so many advanced Pandas classes I have been through, and NONE of them came close to how much I am learning here. And I am truly understanding all the details of how Pandas works now! Finally!! This is definitely the next step I needed to never be embarrassed for not knowing an obscure Pandas function in an interview ever again!

By Vishal Ruparel on 9/15/2022

I am halfway through this course and I am amzed by the delivery and instructor's comprehension and grasp of Pandas. The challanges presented in this course are something definitely what I was looking for and the Alexander is very engaging and hits all the points at once.

I'm a bit more than a novice so this course was very exciting for me. It showed simple ways of doing things that I was struggling with. He has a clear and focused process for cleaning, analyzing, and teasing the data. It also showed a number of visual and other statistical commands that I had never run across before with Python. I really enjoyed this course and already have plans to use what I learned.

By Rogelio A. Ferrol on 2/24/2022

The course for me has been above expectations. It is truly comprehensive and the examples are very well prepared. I found the system followed also very appropriate for this kind of content. You can work at your own pace as the content of the notebook is always on sight. The explanations are really good. As a suggestion for improvement I would have liked it had a bit more explanations and examples on application of SQLite. I would also like it had a bit more explanations on matplotlib. For example I still found it a bit confusing the way in which fig and ax are used and I really struggle to find examples on the internet when I need to do something "special" on a chart (as removing tickmarks, use different kinds of lines, etc..). Lastly I would suggest as an idea for development some material on QuantLib. There is very little available.

By Sewa Nyaya Utthan Foundation on 11/1/2021

Extremely valuable course. Since the teacher takes through the analysis line by line, and starts from basic analysis to very complex analysis in real world, it is very useful. A suggestion: There should be one project exclusively on visualisations to cover some advanced concepts.

By Emanuele Mele on 5/6/2021

The course material and project were extremely useful and practical. Thanks to this course I learned how to work with real cases (including managing and cleaning complex datasets). All processes and steps were clearly explained. The teacher was extremely responsive. It was a great learning experience!

By Thomas Brach on 12/9/2020

The instructor is definitely very knowledgeable and did an excellent job splitting the course in cohesive and increasingly difficult sections. Nonetheless, I feel that the course is seriously missing a "self-teaching" notebook to be able to attempt the exercises on our own. Section 1 had this, but none of the other sections. The result is, you're mostly watching the instructor going through the content but since the queries are already pre-filled and the notebooks lack detailed instructions, you simply run the cells and try to understand the code on the go. it's very difficult to progress without applying. I would suggest providing a self-learning notebook for all sections with detailed instructions, so at least we can attempt the challenges ourselves.

By Mazeen Muhammed on 6/24/2020

Great teaching. Covers most of the stuff. Suggestion to others taking the course, explore more as he teaches you. Take this course if you want to learn most of the things about Pandas and how you can use it for data analysis and not for machine learning.
