4 Different Ways to Clear Console in Python

You must import the os module and use its os.system() method to clear the console programmatically in Python. The os is a built-in library that comes with Python3 installations.

I am using Mac, so I need to write Linux-related commands.

import os def clear_console(): os.system('clear') clear_console()

If you run the above command in your console, it will clear the screen.

For the Windows user, use the following code.

import os def clear_console(): os.system('cls') clear_console()

You can use the lambda function if you don’t want to use the full function.

import os def clear_console(): return os.system('clear') clear_console()

And it will clear the console.

That’s pretty much it for clearing the console in Python.

Method 2: Using the subprocess.call() function

You can use the subprocess.call() function in the subprocess module that allows you to spawn new processes, connect to their input/output/error pipes and clear the console in Python.

Example

import subprocess import os subprocess.call('clear' if os.name =='posix' else 'cls', shell=True)

If you run the above code, it will clear the console.

Method 3: Using the ANSI escape codes

ANSI escape codes are sequences of characters that can be included in a string to specify various types of formatting for terminal output, such as changing the color or cursor position or clearing the console.

Example

It will clear the Python console.

The “\033” is the escape character, and c is the code to reset the terminal.

The “end” argument is set to an empty string to ensure no extra line break is added after the escape code.

Method 4: Using the ipykernel package in Jupyter notebooks

In Jupyter notebooks, you can clear the output of a cell by using the ipykernel package.

The ipykernel package provides an API for controlling the Jupyter kernel, including the ability to clear the output of a cell, or in our case, it is console programmatically.

Example

from IPython.display import clear_output clear_output()

The clear_output() function from the IPython.display module can be used to clear the output of a cell in a Jupyter notebook.

Conclusion

In Python, you can clear the console by using the following methods based on the platform you are using:

For Windows

import os os.system('cls' if os.name == 'nt' else 'clear')

For Linux/Unix

The os.system() method takes different parameters based on your platform because the os.system() function is platform-dependent and may not work on all systems.

Как очистить консоль в Python

В данном руководстве рассмотрим различные способы очистки консоли в Python.

Способ 1: использование модуля os

Используйте команду os.system(‘clear’) для очистки консоли на Mac и Linux в Python и команду os.system(‘cls’) для очистки консоли на платформе Windows. Для программной очистки консоли в Python необходимо импортировать модуль os и использовать его метод os.system(). os — это встроенная библиотека, которая поставляется вместе с установкой Python3.

Я использую Mac, поэтому мне нужно писать команды, связанные с Linux.

Если вы запустите приведенную выше команду в своей консоли, она очистит экран.

Для пользователя Windows используйте следующий код.

Вы можете использовать лямбда-функцию, если не хотите использовать полную.

Способ 2: с помощью функции subprocess.call()

Вы можете использовать функцию subprocess.call() в модуле подпроцесса, которая позволяет создавать новые процессы, подключаться к их каналам ввода/вывода/ошибки и очищать консоль в Python.

Если вы запустите приведенный выше код, он очистит консоль.

Способ 3: использование escape-кодов ANSI

Escape-коды ANSI — это последовательности символов, которые можно включить в строку, чтобы указать различные типы форматирования вывода терминала, например, изменить цвет или положение курсора или очистить консоль.

Код очистит консоль Python.

«\033» — управляющий символ, а c — код для сброса терминала.

Аргумент «end» устанавливается в пустую строку, чтобы гарантировать, что после escape-кода не будет добавлен дополнительный разрыв строки.

Способ 4: применение пакета ipykernel в блокнотах Jupyter

В блокнотах Jupyter вы можете очистить вывод ячейки с помощью пакета ipykernel.

Пакет ipykernel предоставляет API для управления ядром Jupyter, включая возможность очистки вывода ячейки или, в нашем случае, программной консоли.

Clear Screen in Python

While working on the Python terminal (not a console)/interactive shell, some errors occur in the output. So, we have to clean the screen by pressing Control (Ctrl) and L keys simultaneously.

However, sometimes there are situations when the output has to be formatted properly to eliminate issues.

That’s why clearing the screen is based on the amount of output. In this situation, some commands need to be inserted in Python’s script to clear the screen as and when required.

So in this article, we will consider every possible way to clear the screen in Python without having any trouble or errors.

How to Clear Screen in Python Terminal

If you are working on a terminal, then use commands «cls» and «clear» to clear the terminal like this:

For Windows Users

If you are a Windows user and want to clear the screen in Python, you can easily do it using the «cls» command.

This command will instantly clear the screen, as you can see in the below image:

For Linux Users

Linux also has a command to clear screen in Python easily, so use the following command to do it:

Remember there is no specific function, built-in keywords, etc., available to clear the screen. That’s why users need to clear the screen according to them.

Clear Screen in Python Using Functions

Now let’s consider the functions we can use for clearing the screen in Python and remember that you can use these functions in both Windows and Linux.

Using click library

In this method, you can use click library to create a function, and it can work on both Windows and Linux.

# Python program to clear screen using click.clear() function # Import click library import click def clrscr(): # Clear screen using click.clear() function click.clear() print("Screen Cleared") clrscr()

Code Explanation:

In the above example, we are using click.clear() function from click library to clear screen.

This function works in Windows, Linux, and Mac operating systems.

Using \n (Newline character)

The whole way of not clearing the screen is as different as the answer is different. To remove any further error of the line, the user does not need to run the external process completely so that the screen can be cleared.

To clear the screen, you have to print new numbers which are higher than the height and can print something like this («\ n» * 10)

# Python program to clear the screen using \n # ‘\n’ is a newline character def clrscr(): # Print ‘\n’ 10 times print ("\n" * 10) print("Screen Cleared") clrscr()

Code Explanation:

In the above example, we need to clear a few lined of the screen so we use “\n” with print, this will add a newline character and clear x number of lines.

Clear screen program by using os.system method

There are many OS platforms like Windows, Linux, and macOS, so we need different commands to clear the screen. So as you can see in the below syntax, we have used the ‘_’ variable for holding the value of the last expression in the interpreter.

Now we will describe the os.system method to clear the screen in Python without having any troubles. As you can see in the below syntax, we have used the os.system command because It is a string that tells which command needs to be executed.

# Python program to clear the screen using os.system # Import os module import os def clrscr(): # Check if Operating System is Mac and Linux or Windows if os.name == 'posix': _ = os.system('clear') else: # Else Operating System is Windows (os.name = nt) _ = os.system('cls') print("Screen Cleared") clrscr()

Code Explanation:

We got «Screen Cleared» as we have printed it using the above syntax in the output.

In the above example first, we are checking if the operating system is Linux or not by checking the value of os.name method.
If the Operating system is Linux or Mac the value of os.name will be ”posix” .

And if the value of os.name is posix then we will run the function os.system(‘clear’) or else we will run function os.system(‘cls’) .

# Python program to clear screen # This function is applicable for all operating system like Windows, Linux, and OS-X # Import Library platform and os import platform import os def clr_scr(): # Check if the platform is Windows or linux # If Platform is Windows then run command os.system(‘cls’) else os.system(‘clear’) if(platform.system().lower()=="windows"): cmdtorun='cls' else: cmdtorun='clear' os.system(cmdtorun) clr_scr()

Code Explanation:

In the above example first, we check if the platform is Windows or Linux by using platform.system() function.

If the platform is “Windows” then we store the value of a command in the variable “cmdtorun” .

And at the end of the function, we are run the function os.system(cmdtorun) with the variable “cmdtorun” .

Using Subprocess Library

In this example, we have used the subprocess() function to execute an action for clearing the screen in output.

# Python program to clear the screen using subprocess.call() function # Import subprocess library import subprocess def clrscr(): cls = subprocess.call('cls',shell=True) print("Screen Cleared") clrscr()

Conclusion

So this is how you can easily clear the screen in Python using functions or commands in the Syntax. As we have mentioned earlier,

There are many methods to clear the screen in Python without getting any errors. But, in our opinion, a clear screen using a click library is the easiest because it works with both the operating systems Unix, Windows, and macOS. And it doesn’t need checking the OS.
