A simple lottery game in python

If someone has $10 and plans to purchase some lottery tickets. Each lottery ticket costs $2, and the winning prize is random from $0 - 10. gain = random.randint(0, 10) can be used to generate a random int and store it in a variable "gain". First, ask the user to input the number of lottery tickets he wants to buy. If the user inputs any negative or decimal number or positive integer numbers that make the cost of buying lottery tickets exceeding the budget, the program will return to ask the user how many lottery tickets he wants to buy until the user inputs a valid number. Next, the program will first subtract the cost of buying those numbers of lottery tickets from the budget and generate an output of the winning prize for each ticket. Then, the amount of winning prize will be added to user's budget. In the end, provide the user a chance to input whether or not he wants to play the lottery game again. If he inputs "Y", every ticket he bought and gained prize will be cleared and he will receive a brand new $10 and return to the question asking how many lottery tickets he wants to buy again. If he inputs anything else, the program will exit.

Here is an example output:

Money Available: 10 dollar(s)

How many lottery tickets do you want to buy?

The user wants to buy 5 lottery ticket(s)

This will cost 10 dollar(s), your remaining money is 0 dollar(s)
