Issue with error exceptions: Project 1

I'm having a problem with the integer type ValueError in Project 1. I was successful in dealing with the first condition: tickets ordered > tickets available. Then followed with:

except ValueError as err:
    print("Sorry we ran into an issue! {}".format(err))

But what returns is:

"Sorry we ran into an issue! invalid literal for int() with base 10: 'ten' "

Any pointers? Thanks in advance.

This error can happen when passing a string containing a floating point value to int(). From the Stack Overflow post:

>>> str(5/2)
‘2.5’

>>> int(‘2.5’)
  File “<stdin>”, line 1
    int(‘2.5’)
           ^
SyntaxError: invalid character in identifier

>>> int(str(5/2))
Traceback (most recent call last):
  File “<stdin>”, line 1, in <module>
ValueError: invalid literal for int() with base 10: ‘2.5’

>>> int(float(str(5/2)))
