I made a mistake in the code: I can not find where. help me please =)

Question

Task - Ballpark Orders: https://www.sololearn.com/coach/15?ref=app

My code: https://code.sololearn.com/cLW3M85EE8vf/?ref=app

2/5 of the tests are successful, the rest of the tests fail and they are hidden. Anyone have any ideas where I made a mistake?

Answer 1

I think there may be a rounding error here. My advice: change

tax = subtotal * 1.07

to

tax = subtotal * 107/100.

This should stop the rounding error.

Answer 2

You haven't included what to do if i is "NACHOS". You need an extra elif i == "NACHOS":

Answer 3

Yes, it worked! Thanks!

Right now I was thinking about trying to round out the output, but using my curve method:
...
total_with_tax = ("%6.2f" % (subtotal * 1.07))
...

And thank You for Your advice on rounding!

Answer 4

The common way is to use round().

print(round(subtotal*1.07, 2)) should work too I think. The 2 means to 2 decimal places in case you weren't sure.

Answer 5

To better remember, I also checked "round()" - this method also works. Thanks

Answer 6

Russ, thank you!
I added "elif i = = "nachos": ..."

It should have worked, but it didn't... The same result is 2/3

It is logical that the problem is in the 'NACHOS', but what is it?...

Answer 7

Did you try that too?

Answer 8

Yes, both options work. But I think yours is more appropriate.

I don't even know how this thing I wrote works, just copied it from the Internet. *Facepalm*

Your option is simpler and works.
