am i overthinking or what??

so for the very first 'thing to do' was to out put the amount of tickets remaining variable. okay, so i do this,

TICKET_PRICE = 10

ticket_remaining = 100

while ticket_remaining > 0: num_tickets = int(input('How many tickets would you like?: ')) ticket_remaining -= num_tickets print('Tickets remaining: ',ticket_remaining)

any tips on not only keeping it simple, i guess HOW to keep it simple??

I"m not sure what you're asking. Can you rephrase and elaborate a bit?

Hey Steven, well i guess i was asking on tips how to understand exactly what the person is asking for me to do? the example above wants to to output the numbers of tickets left using the vairable.

well i did that but when i should have used a print statement and the format method, i created a while loop. The while loop actualy just comes later on in the project...

i guess im asking why did i go straight an make a while loop and not a simple print statement?

i don know i think i'm just confusing myself honestly i probably am overthinking it. i finished the lessson and created the project on my own..but like i said the beginning i must have just been overthinking it .....

p.s if you can follow anything i just said lol. advice and tips arethe most appreciated!

You are going to far ahead on the trello board. In this video we did not try to get all of the to-dos done. To keep it simple, just do the steps one at a time. This would be an example completing only the to-dos covered in this video:

TICKET_PRICE = 10

tickets_remaining = 100

# Gather the user's name and assign it to a new variable
username = input("Welcome to MasterTicket! What is your name?  ")

# Output remaining tickets using the tickets_remaining variable
print("Hello, {}! There are {} tickets remaining.".format(username, tickets_remaining))

i think i did to def thecost(Amount): if(Amount<=0): raise ValueError("you need to ordaer 1 or more tickets") if(Amount > tickets_remanining): raise ValueError("thats to meny tikets") return (ticket_Amount*ticket_price)

print("there are {} tickets remaining".format(tickets_remanining))

get the users name

user_Name = input("what is your name? ") ticket_Amount = int(input("how meny tickets wolud you like? {} ").format(user_Name)) cost = thecost(ticket_Amount) print("it will cost {} $".format(cost)) though i still cant get raise ValueError not to go all red

import math

TICKET_PRICE = 10
tickets_remaining = 100  
print("There are {} tickets left remaining.".format(tickets_remaining))

def master_ticket(TICKET_PRICE, tickets_requested):
    if tickets_requested >= tickets_remaining:
        raise ValueError("I'm sorry, there are only {} tickets available...".format(tickets_remaining))
    return math.ceil(TICKET_PRICE * tickets_requested)

try: 
    name = input("What's your name?  ")
    tickets_requested = float(input("How many tickets would you like?  "))
    amount_due = master_ticket(TICKET_PRICE, tickets_requested)
except ValueError as err:
    print("Oh no! That is not a valid value. Try again...")
    print("({})".format(err))
else:
    print("That will be ${}".format(amount_due))

This is what I did... I thought I might be overthinking it too, but it works.
