Now I want to have like that:

How many row do you want (€0.8 per rows) :

2

You chose 2 rows

It costs you : 1.6 €

Your round : 1

Choose your 7 numbers for row 1:1 2 3 4 5 6 7

Choose your 7 numbers for row 2:2 6 9 8 7 4 1

Your numbers for row 1 are: [1, 2, 3, 4, 5, 6, 7]

Your numbers for row 2 are: [2, 6, 9, 8, 7, 4, 1]

The winning numbers are [21, 19, 30, 34, 2, 5, 22]

The extra numbers are [8, 9, 23]

Do you want to continue:(Y/N)

If the player say yes,it will run like I did. but if they say no,this program will stop

Please help me as soon as possible! I try my best but I can't do anything!
