How do I modify this to capture errors: 1) num of ticket should be an int 2) number less than tickets remaining?

TICKET_PRICE = 10

tickets_remaining = 100  

while tickets_remaining >= 1:
    print("There are {} tickets remaining".format(tickets_remaining))
    first_name = input("What is your name? ")
    try:
        tickets_to_buy = int(input("Welcome {}! How many tickets do you wanna buy? ".format(first_name)))
        if tickets_to_buy > tickets_remaining:
            raise ValueError ("There are only {} remaining {}".format(tickets_remaining, first_name))
    except ValueError as err:
        print("Oh no, we ran into an issue.{}. Please try again".format(err))
    else:    
        price = tickets_to_buy * TICKET_PRICE
        print("Your price is ${} USD".format(price))
        proceed = input("Do you want to proceed? (Y/N) ")
        if proceed.lower() == "y":
            #Print SOLD and gather credit card information
            print("SOLD!")
            tickets_remaining -= tickets_to_buy
            print("You have {} tickets remaining".format(tickets_remaining))
        else:
            print("Thank you for coming {}".format(first_name))
            print("You have {} tickets remaining".format(tickets_remaining))

print("Sorry tickets are sold out")
