The European Commission proposes eight key competencies that need to be achieved at the end of primary education. One of the competencies is also digital competence, which is increasingly becoming one of the most important competencies of every individual. Digital competence is associated with information and communication skills, and implies the use of computers and networks as basic means for accessing and exchanging information and communication. Informatics, as a key school subject in the implementation of digital competence, has only recently been considered a compulsory subject since the fifth grade of primary school, and this is due to the current curriculum of the subject of informatics, which will be discussed in more detail in this thesis. The curriculum, among other things, presents four domains in the organization of the subject curriculum of informatics, and the domain that will be discussed the most in this thesis is computer thinking and programming. Within that domain, the Python programming language will be presented in a gradual and systematic way through informatics textbooks. The idea of this work is to define the basic concepts of programming in Python applicable in school and to point out the influence of the domain of computer thinking and programming on the student's further development.
