First programs in Python - course 390 rub. from Stepik, training 33 lessons, Date: November 30, 2023.
Miscellaneous / / December 03, 2023
Who is this course for:
- for schoolchildren who are interested in programming and are just starting to write their first programs;
- for those who know Python and continue to hone their skills;
- for those who are going to take the OGE in computer science. The course covers solutions to problems at the OGE level;
- for those who are going to take the Unified State Exam in computer science. The course covers topics that you need to know
for successfully passing the Unified State Exam in computer science.
Why I made this course and continue to work on it.
I am a teacher with extensive teaching experience. My experience suggests that the study of any subject should proceed gradually, from simple to complex. Only then can we talk about a deep understanding of the topics studied. In all the programming courses I know, complex problems are almost immediately given, the solution of which requires complex algorithmic structures and knowledge of all data structures. For beginners, such courses are very difficult. That's why I created this course. For those who are taking their first steps and would like not just to program, but to write code and understand every line of it.
After completing this course, you will be able to confidently solve more complex problems and take more advanced courses.
Moving on is a must ;-)
The course contains a number of problems from school Olympiads in computer science. In them, as a rule, you need to derive a formula or come up with a more complex algorithm. If they seem difficult for you, then you can skip them for now.
Videos were recorded for the first starting lessons. But for all lessons there is a necessary and sufficient theory. All problems proposed in the course can be solved using the theory discussed. That is, you don’t have to Google and look for additional material. If you see someone using something that was not covered in the course to solve problems, it means you are seeing solutions from someone who is honing their skills. Such people are definitely not new to programming.

wellI graduated from Samara State Pedagogical University (SSPU) in 1999. By profession - teacher of mathematics and computer science. Since then I became interested in teaching computer science and programming. I have the highest qualification category.
I have always loved to study myself and pass on knowledge to other people. I do this with great enthusiasm. I completely agree with Plutarch, who said: “A student is not a vessel that needs to be filled, but a torch that needs to be lit, and only the one who burns himself can light the torch.”
