How to Count Word Occurrences in a File Using Python

What are the steps to count word occurrences in a file using Python?

1. What file do we need to read to count word occurrences?

2. Which words do we need to count occurrences for in the file?

3. How do we create a dictionary to store word counts?

4. What method can we use to split the content of the file into words?

5. How do we iterate over each word and update the word counts in the dictionary?

6. How can we print the contents of the dictionary to display word counts?

Steps to Count Word Occurrences in a File Using Python

1. Open the file "inventory.txt" using the `open()` function and store it in a variable.

2. Define the words "cake", "butter", and "sugar" as keys in a dictionary with initial values set to 0 for each.

3. Split the content of the file into words using the `split()` method.

4. Iterate over each word, update the word counts in the dictionary if the word is in the keys.

5. Print the contents of the dictionary to display the count of each word.

Detailed Explanation

To count word occurrences in a file using Python, you first need to open the file "inventory.txt" and read its contents. Then, create a dictionary called `word_counts` with the words "cake", "butter", and "sugar" as keys and initialize their values to 0.

After splitting the file content into words, iterate over each word. If the word is found in the keys of the dictionary, increment the count for that word. Finally, print the contents of the dictionary to display the count of each word.

In the provided Python program, the file is read using the `open()` function, and the content is stored in a variable. The dictionary `word_counts` is initialized with the words to count. The content is split into words, and the count of each word is updated in the dictionary. The final step involves printing the contents of the dictionary to display the word counts.
