This Python script reads a text file, counts the frequency of each word, and displays the top 10 most common words.

1. Read the File
   The script opens the specified text file and reads its entire content into memory. It converts all text to lowercase to ensure that word counting is case-insensitive (e.g., "The" and "the" are treated as the same word).

2. Extract Words Using Regular Expressions
   Using a regular expression (\b[\w']+\b), it extracts all words from the text. This pattern matches sequences of letters, digits, underscores, and apostrophes, so words like "don't" are correctly captured.

3. Count Word Frequencies
   The extracted words are counted using Python’s collections.Counter class, which efficiently calculates how many times each word appears.

4. Display the Top 10 Words
   The script retrieves and prints the 10 most common words along with their counts.

To use this script, call the top_10_word_frequencies function with the path to your text file:

top_10_word_frequencies('yourfile.txt')
