### Python Problem 7: Solution | Python Tutorials For Absolute Beginners In Hindi #116

This is the solution to Python Problem # 7. You can see the problem statement below:-

#### Problem Statement:-

You are given few sentences as a list (Python list of sentences). Take a query string as an input from the user. You have to pull out the sentences matching this query inputted by the user in decreasing order of relevance after converting every word in the query and the sentence to lowercase. Most relevant sentence is the one with the maximum number of matching words with the query.

Sentences = [“Python is cool”, “python is good”, “python is not python snake”]

“Python is”

#### Output:

3 results found:

1. python is not python snake
2. python is good
3. Python is cool
