Hầu hết thời gian, trong khi làm việc với Shell/thiết bị đầu cuối tương tác Python (không phải là một bảng điều khiển), chúng tôi kết thúc với đầu ra lộn xộn và muốn xóa màn hình vì một số lý do. Trong một shell/thiết bị đầu cuối tương tác, chúng ta chỉ có thể sử dụng

Nhưng, điều gì sẽ xảy ra nếu chúng ta muốn xóa màn hình trong khi chạy tập lệnh Python? Thật không may, không có từ khóa hoặc chức năng/phương thức tích hợp để xóa màn hình. Vì vậy, chúng tôi làm điều đó một mình.

Xóa màn hình trong hệ điều hành Windows

Phương pháp 1: Màn hình rõ ràng trong Python bằng CLS

import os

os.system('cls')

import os

os.system('cls')

import os

os.system('cls')

Bạn có thể chỉ đơn giản là CL CLS để xóa màn hình trong Windows.
import osfrom os import system” but with that, you have to change system(‘clear’) to os.system(‘clear’). 
Python3
Ví dụ 2: Màn hình rõ ràng trong Python bằng cách sử dụng Clear
Bạn cũng chỉ có thể nhập khẩu OS OS OS thay vì từ hệ thống nhập hệ điều hành, nhưng với điều đó, bạn phải thay đổi hệ thống (’rõ ràng) thành hệ điều hành (‘ rõ ràng). & NBSP;
