Table of Contents

• Use case of Dictionary

Important funtions to remember:

1. re.findall(r'\b[a-z]{3,15}\b', text_string)

return all the words with the number of characters in the range [3-15]. Starting from 3 will help in avoiding words that we may not be interested in counting their frequency like if, of, in, etc., and words having a length larger than 15 might not be correct words.

2. dict.get()

3. dict.key()

4 .lists and Dictionary

5. word frequency in text file
