Course Syllabus

Abstract

The course is aimed to introduce data analysis using Python. The first part of the course is dedicated to the basics of Python where the topics related to the basics of this programming language are covered. The second part of the course introduces the work with real-life data within social sciences and international relations. The course is specifically designed for people with no prior experience in programming.
