Python Built-in Functions

Python built-in functions are ready-made methods that come with Python itself, designed to perform common tasks. Think of them as pre-written code you can use directly without defining them yourself. These functions cover a wide range of operations, from printing output (print()) and getting user input (input()) to mathematical calculations (abs(), max(), min(), sum()) and type conversions (int(), str(), float()). Using Python built-in functions is essential for any beginner programmer because they save time and effort, making your code more concise and efficient. They are the foundation of many Python programs.
