CIS4930 Final Exam Topics
The Final Exam will be comprehensive and consist of multiple choice and short
answer questions.
I want you to have an overall understanding of the basics of Python and what
tools/libraries we’ve covered and basically how they’re used.
There will be code questions where you have to describe what is happening or
what the output is. You may have some code-writing questions but I will give you
any function signatures you need. You do not need to “memorize” how methods
of packages are called, you only need to know what they do.
