+The aim of this project is to replicate a dice and generate a random number from the numbers 1 to 6.<br><br>

+The above code defines a function called "roll_dice( )" which interacts with the user.<br>
+It prompts the user to give an input and if the input is k,the code proceeds further to generate a random number or gives the message of invalid input and asks the user to try again.<br>
+After the dice has been rolled once, the function asks the user whether they want a reroll in the form of a yes or no question.The dice is rolled again if the user gives 'yes' as an answer and exits the code if the user replies with anything other than yes.
