Tệp mẫu.txt
Đầu tiên, chúng tôi tạo một tệp văn bản trong đó chúng tôi muốn đếm các từ trong Python. Đặt tệp này được mẫu.txt với các nội dung sausample.txt with the following contents
Mango banana apple pear Banana grapes strawberry Apple pear mango banana Kiwi apple mango strawberry
Ví dụ 1: đếm các lần xuất hiện của mỗi từ trong một tệp văn bản đã cho Count occurrences of each word in a given text file
Ở đây, chúng tôi sử dụng một vòng python để đọc từng dòng và từ dòng đó, chúng tôi đang chuyển đổi từng dòng thành thấp hơn cho số lượng duy nhất và sau đó chia từng từ để đếm số của nó.

Làm thế nào để bạn đếm số lần xuất hiện của một từ trong một tệp?
Chỉ sử dụng grep -c sẽ đếm số lượng dòng chứa từ phù hợp thay vì số lượng tổng số trận đấu.Tùy chọn -O là những gì bảo GRP xuất mỗi trận đấu theo một dòng duy nhất và sau đó WC -L bảo WC đếm số lượng dòng.Đây là cách tổng số từ các từ phù hợp được suy ra.. The -o option is what tells grep to output each match in a unique line and then wc -l tells wc to count the number of lines. This is how the total number of matching words is deduced.
Làm cách nào để đếm số lần một từ xuất hiện trong một tệp văn bản?
