This lecture uses IDE Pyzo (or rarely terminal) to exercise Python statements and solve problems.
Make sure that you have Pyzo and command-line terminals available.
Then, you will be fine to follow this lecture.
The primary goal of student learning is to follow the first dimension of lecture.
It means that you may go back after this web page and go the next module.
Only for those who want to dive into a deeper level of the same module,
there will be the second dimension of lecture.
This level lecture gives more useful Python statements, some of those may be more difficult to understand.
Therefore, more practices are expected.
In the third dimension of lecture, zero or more applications are discussed.
Not all of the modules are ready to discuss various application problems, but will be done in the future!
