About this course

Do you want to write faster, more efficient Python code? Understanding how long your code takes to run is the first step toward optimization. This course guides you through building a custom performance timer in Python. By the end of this course, you will be able to create and use your own reusable timer context manager to precisely measure the execution time of any Python code block, enabling you to identify and target performance bottlenecks. What you'll learn: * Understand Python's special methods and object-oriented programming fundamentals * Implement custom context managers using the `__enter__` and `__exit__` methods * Build a robust and reusable timer class for accurate code execution measurement * Apply basic type hints to enhance the readability and maintainability of your Python code * Practice integrating your custom timer to analyze the performance of various code snippets * Discover common patterns for identifying and improving inefficient Python code This course begins with foundational Python concepts, progressing to the principles of context managers, and then to the practical implementation and application of a performance timer. You will learn to write cleaner, more performant Python. This course is for beginner Python developers who want to deepen their understanding of object-oriented programming and learn practical techniques for code optimization. No prior experience with performance tuning or advanced Python concepts is required. Start your journey to writing more performant Python code today.
