Front End Web Development Techdegree Student 3,460 PointsString input error message
My code handles the errors possible just fine (ie, Requested tickets too many, or a string was input) I just want to make the error message cleaner when I input a string. Right now it reads: "Invalid Literal for int() with base 10: 'v'" if the request is simply too large, it generates the custom message we made.
num_tickets = int(num_tickets)
#raise a ValueError if the request is for more tickets than are available
if num_tickets > tickets_remaining:
raise ValueError("There are only {} tickets left".format(tickets_remaining))
except ValueError as err:
print("That is not a valid entry. {}. Please enter number of tickets you wish to purchase".format(err))
can someone help me here?
Thanks!

Try catching a TypeError and setting a message for that in your code! :-)
