Python built-in functions: the key to improving the efficiency of your code

Python’s built-in functions are a set of powerful and useful tools that help you write your code faster, more efficiently, and more readably. In this article, we introduce and teach some of the most commonly used internal Python functions.

Getting to know Python’s built-in functions: essential tools for every programmer

Python’s built-in functions are a set of functions that exist by default in Python and do not require installing or importing external libraries. These functions are used in various fields such as working with numbers, strings, lists, files, etc. Familiarity with these functions can help you improve your code dramatically and save you time and energy.

Use of functions to improve code efficiency

One of the most important benefits of using built-in functions is to improve code efficiency. By using these functions, you can make your code significantly shorter and more readable. Also, many of these functions are written in an optimized way and thus guarantee faster code execution. In the following, we will introduce and teach some of the most commonly used Python internal functions:

print() function

The print() function is one of Python’s most widely used built-in functions that allows you to send information to standard output (usually the screen). This function can print different types of data such as numbers, strings, lists, etc.

len() function

The len() function allows you to get the length of an object. This function is used for different types of data such as strings, lists, tuples, etc.

range() function

The range() function creates a sequence of integers that can be used to iterate through loops. This function can be called with one, two or three arguments.

input() function

The input() function allows the user to enter information via the keyboard. This function can take an optional message as an argument to be displayed to the user.

type() function

The type() function allows you to get the type of an object. This function takes an object as argument and returns its type as output.

These are just a few of the built-in Python functions introduced here. Python has a wide set of built-in functions, each of which has its own uses. By knowing these functions and how to use them, you can dramatically improve your code and save yourself time and energy.
