Techniques to Count Duplicate Words in a Sentence

How can we accurately count duplicate words in a given sentence?

What is the process to identify and display the number of duplicate words in a sentence correctly?

Counting Duplicate Words in a Sentence

Following the instructions, we need to follow a specific process to count duplicate words accurately in a sentence. Let's break down the steps:

Step 1: Split the Sentence

To start, we split the sentence into individual words. This is done by using the split() method, which separates the sentence into a list of words. Since we want to treat uppercase and lowercase letters equally and there is no punctuation, we convert the entire sentence to lowercase using the lower() method before splitting it.

Step 2: Create a Dictionary

Next, we create a dictionary to store the frequency of each word. Each word in the sentence becomes a key in the dictionary, and its corresponding value represents how many times it appears in the sentence.

Step 3: Calculate Word Frequencies

We then proceed to count the frequency of each word in the sentence. If a word is already present in the dictionary, we increment its count. If it's a new word, we add it to the dictionary with a count of 1.

Step 4: Print the Results

Finally, we display the count of duplicate words in a formatted table. Each row contains a word and the number of times it occurs as a duplicate in the sentence.
