Predefined functions, sometimes known as built-in functions, are a set of functions provided by a programming language that can be used to perform specific tasks without the need for the programmer to implement them from scratch.
These functions are invaluable as they save time and effort, allowing programmers to leverage existing, efficient implementations.
Predefined functions can carry out various tasks, ranging from mathematical operations to data manipulation.
- Examples include functions like
print()
in Python to display output or len()
to find the length of a data structure.
- These functions have standardized inputs and outputs, making them reliable and easy to use.
- Predefined functions increase productivity by streamlining the coding process, allowing developers to focus on more complex aspects of program development.
