About Lesson

In terms of using pandas and NumPy, as well as Python in general, at this stage of the course, you can say you have acquired enough knowledge and basic practical skills to be somehow independent while learning new related material. Yes, there are plenty of other tools that youll need support for. But surely, your current level allows you to free your mind from the fundamentals and focus on more complex topics such as the next one. It is about importing data in Python. Although the latter is not always a straightforward task, it is indeed a tool that everyone interested in doing data cleaning, preprocessing, or analysis with Python, must have under their belt.

Please allow me to use the occasion to remind you: you can re-watch a video, if necessary, or repeat an exercise that you have found challenging in this section. We stand behind the idea that practice is essential while learning new concepts. So, to help you advance we will challenge you with exercises in the sections to come, too.

Good luck and thank you for watching!
