tickets_remaining = tickets_remaining - tickets_needed

tickets_needed is the prompt that the user replies to

You'd need to post more of the code to be sure, but if "tickets_needed" is assigned from an "input" it would be a string. You'd need to convert it to a number before you could subtract it.

Automatically python defaults to a string datatype and this is why you need to simply convert tickets_needed:

tickets_remaining = tickets_remaining - int(tickets_needed)

Coding can definitely make you rethink your life choices, but its the ride that makes it enjoyable. Take a break even if it is for a day or two and come back to it. I have been sketching on my ipad with procreate to help take the edge off. Dont give up ever you will be much happier once you complete your goal.

sorry I love coding but when I keep getting it wrong I lose it...I don't seem to have patience with it. So after following the suggestions here I do believe I have finally nailed it to the wall...thx

Perhaps having lots of opportunity to practice having patience with yourself will be a bonus benefit of learning programming. :wink:
