Built-in Functions
Built-in functions in Python are predefined functions that are readily available for use in any Python program without requiring additional specifications or definitions. One of these built-in functions is the print()
function, which we have already used. We didn't need to define this function, write its body, or specify the return value; we simply called it and provided inputs. There are many built-in functions in Python. Let's consider some of the most commonly used ones:
print()
: Outputs a specified message or variable to the console.
1print("My message")
len()
: Returns the number of elements in an object, such as a string, list, or tuple.
12word = "Codefinity" print("Word length:", len(word))
sum()
: Computes the total of a sequence of numbers.
12numbers = [5, 2, 3] print("Sum of numbers:", sum(numbers))
max()
and min()
: Return the maximum or minimum value from a sequence.
123numbers = [5, 2, 3] print("The largest among the numbers:", max(numbers)) print("The smallest of the numbers:", min(numbers))
You might already be familiar with these functions, or perhaps not. The key in this chapter is to understand the difference between built-in functions and those you create yourself.
