Computational Thinking with Python
Mock Exam
Course Introduction
Computational Thinking with Python is a foundational course that introduces students to the core concepts of problem-solving and logical reasoning using the Python programming language. Through a combination of theory and hands-on programming exercises, students learn to break down complex problems, design algorithms, and implement solutions that can be automated by computers. The course emphasizes the development of skills such as abstraction, pattern recognition, and decomposition while building proficiency in Python syntax, data types, control structures, and functions. By applying computational thinking to real-world scenarios, students acquire practical experience in coding and develop analytical skills essential for further studies in computer science and related fields.
