Synthetic general description
The course introduces some fundamentals principles of Computer Scisnce but mostly focuses on an practical introduction to Programming using Python as reference language.
Focusing on the mosto common practices of Scientific computing imperative as well object oriented paradigm of programming will be considered. Some minor reference will be provided toward ad advanced use of spreadsheet computation models.
Elementary data structures (list, string, dataframes) will be introduced. Basic programing structures: conditional and case based control, iteration, recursion.
Functions and code factoring will be considered as well.
General educational objectives of teaching in terms of expected learning
Knowledge and understanding: the primary objective of the course is the students' acquisition of the "mind set" of programming, as well as an operative knowledge of Python and of some spreadsheet utilities.
Applying knowledge and understanding: it intends to provide the tools to achieve the following practical and professional skills:
- To analyze computational problems and to code algorithmic ideas for their resolution;
- To design, to describe, to implement and debug Python programs with professional tools;
- To use built-in data structures for data management in scientific computing;
- Understanding simple recursive algorithms;
- To use specific libraries for scientific calculation;
- To be able to read documentation of libraries.
- To use, modify and create efficient and interactive spreadsheets.
Making judgements: through the examination of code examples and numerous practice exercises, the learner will be able, both independently and in a cooperative manner, to analyze problems and design and implement related software solutions.
Communication skills: the student will acquire the necessary communication skills and expressive appropriateness in the use of technical verbal language in the context of computer programming.
Learning skills: the course aims to provide the learner with the necessary theoretical and practical methodologies to be used in professional contexts and, in particular, the ability to formulate and implement ad-hoc algorithms for solving new computational problems as well as the possibility of easily and quickly acquiring other programming languages.
The course will include:
a) frontal classes of mostly theoretical content (blackboard and slides) approx 10 hours;
b) interactive laboratory classes with exercise and direct experiencs (laptop projection, internet connection), students will be encouraged to use their own laptops (not mandatory) for approx 50 hours;
The classes will be held in presence (but different decisions of the authorities).
Hands-on learning and reference to typical case studies will be used through the full course.
No prerequisite is mandatory.
It will help a basic knoledge of spreadsheet usage and elementary notions of math and logic. Problem solving attitude and experience of rigorous quantitative thinking will be very helpful.

b) an interective discussion of the solution developed in the previsou exercise (20% of the evaluation)
Given some data (in a list or dictionary format) extract informatin about them (elementary statistical descriptors, data cleaning, data aggregation tasks).
Given some data in a spreadsheet extract informatin about them (elementary statistical descriptors, data cleaning, data aggregation tasks).
