-# <h1> Problem Statement: Stock Market Analysis and Prediction
-# 
-# Explanation: Our aim is to create software that analyses previous stock data of certain companies,
-# with help of certain parameters that affect stock value. We are going to implement these values in data mining algorithms.
-# This will also help us to determine the values that particular stock will have in near future.
-# We will determine the Month’s High and Low with help of data mining algorithms.
-# In this project we are going to take a five years of stock data for our analysis and prediction
