Many of the topics in this course build upon what is learned in CCCS 610. If you are taking that course in parallel during the same term, no worries, you will do just fine — it is not a pre-requisite, rather a helpful synergy. Some learners may be taking this course as a stand-alone, which is also perfectly fine, and are nonetheless welcome to take CCCS 610 at a later time for a more computational view of the skills honed in this course.
In CCCS 610, we often rely on pseudo-random numbers for data. This module is no different, in that sense. This course, however, leaves the program code outside the spotlight to focus on the mathematical concepts more than on the details of the implementation. Interested participants who already took 610 are nonetheless encouraged to experiment with how to apply what we learn in 620 and try out their wings on how much of it to replicate in Python. Such explorations are great for building a personal portfolio of achievements in a public code repository such as Github.
