Why does the int function not work when I use it with the following code?

To clarify...every time I put in the number three in words instead of a number, I get an error message. Isn't the int function supposed to extract that to the number "3"?

TICKET_PRICE = 10

tickets_remaining = 100

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

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

print("Hello, {}. ".format(name)) number_of_tickets = input("How many tickets would you like? ") number_of_tickets = int(number_of_tickets)

price_of_tickets = number_of_tickets * TICKET_PRICE

print("The total price for your tickets is ${}.".format(price_of_tickets))

No, the int function tries to convert whatever is placed in its parentheses to an integer. Examples:

  • int("3") would return 3
  • int("test") would return an error as that can't be converted to a numeric value.
  • int("three") would also return an error as python can't map the written word of a number to its value.

Ah okay! So there is no way to convert the word "three" into the number 3 in python? (assuming this is for user input). I would just have to create an error message or "exception" to let them know they need to put in a numeral instead of writing out the number?
