Hướng dẫn python program to count number of lines words and characters in a file - chương trình python để đếm số dòng từ và ký tự trong một tệp

Điều kiện tiên quyết: Xử lý tập tin trong Python File Handling in Python

Đưa ra một tệp văn bản fname, nhiệm vụ là đếm tổng số ký tự, từ, khoảng trắng và dòng trong tệp. Như chúng ta đã biết, Python cung cấp nhiều tính năng và mô-đun được xây dựng để xử lý các tệp. Hãy để thảo luận về các cách khác nhau để tính tổng số ký tự, từ, khoảng trắng và dòng trong một tệp sử dụng Python. & NBSP;

Nhận số lượng ký tự, từ, khoảng cách và dòng trong một tệp

Cách tiếp cận ngây thơ để có được số lượng ký tự, từ, khoảng trống và dòng trong một tệp

Trong cách tiếp cận này, ý tưởng là giải quyết nhiệm vụ bằng cách phát triển logic của chúng ta. Không sử dụng bất kỳ chức năng tích hợp nào của Python, tổng số ký tự, từ, khoảng trắng và dòng của tệp sẽ được tính toán. Dưới đây là việc thực hiện phương pháp trên. & NBSP;

Sử dụng một số chức năng tích hợp và chức năng mô-đun hệ điều hành

Theo cách tiếp cận này, ý tưởng là sử dụng phương thức mô -đun HĐH OS.LINEEP [] để tách các dòng trên nền tảng hiện tại. Khi máy quét phiên dịch cuộc gặp gỡ OS.LINEEP, nó thay thế nó bằng ký tự \ n. Sau các hàm Dải [] và Split [] sẽ được sử dụng để thực hiện nhiệm vụ. Nhận thêm ý tưởng về các hàm Dải [] và Split []. Dưới đây là việc thực hiện phương pháp trên. & NBSP;
