Hướng dẫn count the repeated words in string in python - đếm các từ lặp lại trong chuỗi trong python
Viết mã python để tìm tần số của mỗi từ trong một chuỗi đã cho. Ví dụ: Show Input : str[] = "Apple Mango Orange Mango Guava Guava Mango" Output : frequency of Apple is : 1 frequency of Mango is : 3 frequency of Orange is : 1 frequency of Guava is : 2 Input : str = "Train Bus Bus Train Taxi Aeroplane Taxi Bus" Output : frequency of Train is : 2 frequency of Bus is : 3 frequency of Taxi is : 2 frequency of Aeroplane is : 1 Được đề xuất: Vui lòng thử cách tiếp cận của bạn trên {IDE} trước, trước khi chuyển sang giải pháp.{IDE} first, before moving on to the solution.Cách tiếp cận 1 bằng danh sách (): & nbsp; 1 Split the string into a list containing the words by using split function (i.e. string.split()) in python with delimiter space. Note: string_name.split(separator) method is used to split the string by specified separator(delimiter) into the list. If delimiter is not provided then white space is a separator. For example: CODE : str='This is my book' str.split() OUTPUT : ['This', 'is', 'my', 'book'] 2. Khởi tạo một danh sách trống mới. & NBSP; Initialize a new empty list. 3. Bây giờ hãy nối từ vào danh sách mới từ chuỗi trước nếu từ đó không có trong danh sách mới. & NBSP; Now append the word to the new list from previous string if that word is not present in the new list. 4. Lặp lại trong danh sách mới và sử dụng chức năng đếm (tức là chuỗi.count (Báo chí [Lặp lại])) để tìm tần số của từ ở mỗi lần lặp. Iterate over the new list and use count function (i.e. string.count(newstring[iteration])) to find the frequency of word at each iteration. Note: string_name.count(substring) is used to find no. of occurrence of substring in a given string. For example: CODE : str='Apple Mango Apple' str.count('Apple') str2='Apple' str.count(str2) OUTPUT : 2 2 Implementation: Python3

The count() method is a built-in function that takes an element as its only argument and returns the number of times that element appears in the list.
Làm thế nào để bạn đếm số lần một từ được lặp lại trong một chuỗi?Cách tiếp cận: Đầu tiên, chúng tôi chia chuỗi theo khoảng trắng trong a.Sau đó, lấy một số lượng biến số = 0 và trong mọi điều kiện thực sự, chúng tôi tăng số lượng lên 1. Bây giờ chạy một vòng lặp ở độ dài 0 đến chiều dài của chuỗi và kiểm tra xem chuỗi của chúng tôi có bằng từ này không. |
