What is a built-in function?
A built-in function refers to a function that is built into a programming software without the need for importing it. In simpler terms, these are functions that can be called in Python without importing any external modules or libraries. Examples of built-in functions in Python include print(), str(), and int().The official Python documentation provides a list of different built-in functions available in Python, along with their usage. It's important to note that built-in functions may vary across different versions of Python, so it's essential to choose the appropriate Python version.
Syntax of Built-in Functions
Most built-in functions can be used by simply typing the function name followed by parentheses. For example, print() can be used by typing print("Hello World") directly in the code. However, it's important to consider the function's parameters. For instance, print(x) where x can be a string, float, or integer.
Five commonly used built-in functions:
- print() : Used to display information on the command line, often used for debugging purposes.
- abs() : Returns the absolute value of a number. For example, abs(-1) will return 1.
- round() : Rounds a decimal number to the nearest integer. For example, round(3.7) will return 4.
- min() Find the value among the elements of,iterable .For example, min(3, 4, 5) will return 3.
- max() Find the value among the elements of,iterable For example, max(3, 4, 5) will return 5.
