Traceback/Value Error for Using Int()

I am getting a traceback/Value Error error for making num_tickets and integer.

treehouse:~/workspace$ python masterticket.py
There are 100 tickets remaining.
What is your name? Sam
Traceback (most recent call last):
File "masterticket.py", line 19, in <module>
num_tickets = int(num_tickets)
ValueError: invalid literal for int() with base 10: 'How many tickets would you like, Sam? '


tickets_remaining = 100

Output how many tickets remaining using tickets_remaining variable

print("There are {} tickets remaining.".format(tickets_remaining))

Gather the users name and assign it to a variable

name = input("What is your name? ")

promt user by name and ask how many tickets they would like

Calculate the price and assign to variable

num_tickets = ("How many tickets would you like, {}? ".format(name)) num_tickets = int(num_tickets)

amount_due = num_tickets * TICKET_PRICE

print("The total due is {}".format(amount_due))

num_tickets = input(("How many tickets would you like, {}? ".format(name)))

Where you are assigning the num_tickets you forgot to make it an input() You've already done this with the name so I think you just missed it by accident
