Weird Math display

So my code on total = number_tickets * TICKET_PRICE while displaying in my print statement instead of giving out say 30 for 3 tickets, it outputs 333

I'm not sure what's wrong?

TICKET_PRICE = 10

tickets_remaining = 100

Output how many tickets are remaining using the tickets_remaining variable

print("There are {} left to purchase!".format(tickets_remaining))

Gather the users name and assign it to a new variable

usersname = input("please enter your name here: ")

prompt the user by name and ask how many tickets they would like

number_tickets = input("Hello {} how many tickets are you interested in today? ".format(usersname))

calculate the price (number of tickets by price) and assign to a variable

total = number_tickets * TICKET_PRICE print("Ok {}, {} tickets at 10 bucks a ticket will run you {}".format(usersname, number_tickets, total), "still interested?")

output the price to the screen

The result of an "input" is a string, so that's what is in "number_tickets". And when you "multiply" a string by a number, you get that string repeated as many times as the number.

To get the expected value, convert the string to a number with the "int()" function.

It's the input value that needs to be converted into a number before multiplying:

    total = int(number_tickets) * TICKET_PRICE

And for future postings, use Markdown formatting to preserve code appearance, or share the entire workspace by making a snapshot and posting the link to it.

so I want to write it was total = int(number_tickets * TICKET_PRICE)

I thought I tried that and got the same results. I'll try again tonight when I get off of work

I had the same issue. It was writing the amount of tickets as a string and multiplying it by the ticket price, so it just wrote the answer out a bunch of times.

What I did was write it as

tickets_wanted = int(input("Hello {}, how many tickets would you like? ".format(name))

cost = int(tickets_wanted * ticket_price)
