Refactored code using list comprehensions for improved readability and potential performance gains (data_analysis.py, lines 95-105).Also fixed a spelling mistake in README.md

Fixes

Optimizes the code performance and make the code more readable

Description

Reduced memory usage: The changes in the code avoids creating and discarding temporary tokens lists for each tag. Instead, it directly creates a list comprehension with the lowercase words, minimizing memory churn.
Conciseness and readability: The use of list comprehension in the updated code leads to a more concise and arguably more readable code. It expresses the step of splitting, lowercasing, and appending in one line, improving code clarity.
