Hướng dẫn count repeated words in a string python - đếm số từ lặp lại trong chuỗi python

Viết mã python để tìm tần số của mỗi từ trong một chuỗi đã cho. Ví dụ:

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

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
