Python console clear all

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.

How to Clear Screen in Python?

Python os module is imported to clear the console screen in any operating system. The system() method of the os module with the string cls or clear as a parameter is used to clear the screen in windows and macOS/Linux, respectively.

Introduction to Python Clear Screen

Suppose there is a case where you have given the information of 3 students, and you have to print their details in a way like first there will be information of student 1 , then after some time information of student 2 will be displayed and then finally the information of student 3 will be displayed. So, in that case, we will have to clear the python console each time after displaying information about each student.

Image Explanation of the above Example

In an interactive shell/terminal , to clear the python console, we can use the ctrl+l command, but in most cases, we have to clear the screen while running the python script, so we have to do it programmatically.

We can clear screen programmatically, and it helps us to format the output in the way we want. We can also clear the output whenever we want many numbers of times.

How to clear the python console screen?

Clearing the console in python has different methods for different Operating Systems. These are stated below:

• In Windows: For clearing the console in the windows operating system, we will use the system() function from the os module with the ‘cls’ parameter.

Syntax of the system() function: system() function is in the os module, so the os module needs to be imported before using the system() function in Windows. After importing the os module, the string parameter ‘cls’ is passed inside the system function to clear the screen.

• In Linux and MacOS: For clearing the console in Linux and Mac operating systems, we will use the system() function from the os module with the ‘clear’ parameter.

Syntax: os module needs to be imported before using the system() function in Linux. After importing the os module string value parameter ‘clear’ is passed inside the system function to clear the screen.

• Ctrl+l: This method only works for Linux operating system. In an interactive shell/terminal, we can simply use ctrl+l to clear the screen.

Example of Python Clear Screen

Example 1: Clearing Screen in Windows Operating System

Let’s look at an example of the clear screen in python to clarify our understanding.

We will use the above-stated system() function for clearing the python console.

First, we will print some Output; then we will wait for 4 seconds using the sleep() function to halt the program for 4 seconds, and after that, we will apply os.system(‘cls’) to clear the screen.

The output window will print the given text first, then the program will sleep for 4 seconds, then the screen will be cleared, and program execution will be stopped.

Example 2: Clearing the screen, then printing some more information in Windows Operating System.

First we will print some Output, then we will wait for 1 second using the sleep() function, and after that, we will apply os.system(‘cls’) to clear the screen.

After that, we will print some more information.

The output window will print the first information, then the program will sleep for 1 second, and the screen will be cleared, and then it will print the second information. Again the program will sleep for 1 second, and at last, the program will be stopped after printing the final batch of information.

Example 3: Clearing Screen in Linux Operating System

We will use the above-stated system() method for clearing the python console.

First, we will print some Output; then we will wait for 5 seconds using the sleep() function, and after that, we will apply os.system(‘clear’) to clear the screen.

The output window will print the given text first, then the program will sleep for 5 seconds, then the screen will be cleared, and program execution will be stopped.

Example 4: What if we don’t know what OS we are working on?

There can be a case where we must first determine what OS we are working on. So, we will first determine whether the os is Windows, Linux, or Mac.

For Windows, the os name is «nt» and for Linux or mac, the OS name is «posix».

So we will check the os name and then accordingly apply the function.

For this case, the os name is nt , so windows console will be cleared after 2 seconds of program sleep, and then it will be terminated.

Conclusion

Now that we have seen various examples of how to clear the screen in python let us note down a few points.

• Clearing Screen can be done programmatically, and also it helps us to format the output the way we want.
• For clearing the console in the windows operating system, we will use the system() method from the os module with the ‘cls’ parameter.
• For clearing the console in Linux operating system, we will use the system() method from the os module with the ‘clear’ parameter.
• For windows, the os name is nt , and for Linux, it is posix , so we can also first determine the os and then clear the screen.
