Hi all!
What am I doing wrong here? It always says that the value of "decades" is wrong. I tried to divide by 10 and by 10.0 but either way it doesn't work.
The funny thing is that I did this challenge a couple of weeks before and I solved it just fine. I have just started Python again from the beginning because I forgot the most of it :)
age = 31
days = age * 52 * 7
decades = age / 10.0

I've just tried the challenge again and get the same result as you.
First with an integer "10" which results in a "...should be a float" error and then the same issue as you.
I think it is a Treehouse issue - your code seems fine.
Edit : Andrew's solution works with casting as a float but I'm fairly sure I didn't do that first time I did the challenge.

I was also thinking that there is something wrong with the Workspace but everything is ok. Andrew solved it.
But thank you too!

Courses Plus Student 94,610 PointsAs of right now, age / 10 still doesn't pass.
I'm pretty sure that has worked for others.
I think this course is using python 3.x?
According to the python docs, division of integers will result in a float. You would have to use floor division, //, to get an integer result.
The / (division) and // (floor division) operators yield the quotient of their arguments. The numeric arguments are first converted to a common type. Division of integers yields a float, while floor division of integers results in an integer; the result is that of mathematical division with the ‘floor’ function applied to the result. Division by zero raises the ZeroDivisionError exception.
12 / 10 should yield 1.2 and 12 // 10 should yield 1
I don't think this is the case if the challenge is checking against a 2.x version of python.
I would say that the challenge still isn't working then if it's going by a 3.x version.

Treehouse Guest TeacherEverything should be running Python 3.4, but I'll double-check with the devs to make sure.

Treehouse Guest TeacherJust tested this CC again and it seems to be fixed. Your answer should get you to the next step.

Now it works just fine. I tried similar things before like wrapping the "float" method around "age" and "10" etc. but I did not wrap the whole statement.
This works:
Thank you!
