What are Built-in Functions?

Python comes with a set of built-in functions that are always available — no import needed. These functions handle common tasks like getting input, printing output, converting data types, and working with collections.

Commonly Used Built-in Functions

Python Built-in Functions

Function	Description	Example
print()	Displays output to the console	print("Hello")
input()	Gets text input from the user	name = input("Your name: ")
int()	Converts a value to an integer	int("25")
float()	Converts a value to a float	float("3.14")
str()	Converts a value to a string	str(100)
len()	Returns the length of a string or list	len("Hello")
type()	Returns the data type of a value	type(42)
round()	Rounds a number to given decimal places	round(3.14159, 2)
abs()	Returns the absolute value	abs(-10)
max()	Returns the largest value	max(3, 7, 2)
min()	Returns the smallest value	min(3, 7, 2)
range()	Generates a sequence of numbers	range(1, 10)

Examples

# len() - string length name = "PictoBlox" print(len(name)) # 9 # max() and min() print(max(10, 5, 8)) # 10 print(min(10, 5, 8)) # 5 # round() print(round(3.14159, 2)) # 3.14 # abs() print(abs(-42)) # 42
