Ronny De Winter completed this course, spending 2 hours a week on it and found the course difficulty to be very easy.
This is a basic introduction to Python for whoever wants to start with data science and AI. If you are completely new to Python you will probably need more exercise than just this course. For people with Python experience, this can be a good rehearsal if your skills are a bit rusty.
The Coursera certificate is not worth the money in my opinion. If you are happy with an IBM certificate instead you can follow the same course for free at https://cognitiveclass.ai/courses/python-for-data-science including the certificate
