Its telling you to join variables names to the email_greeting to form the sentence.

So like this.

name = "Khaleel"
treehouse = "Tree" + "house"
email_greeting = treehouse + " loves " + name

Finally, create 2 new variables, one named estimate that holds the rounded number of decades you've lived and, one named summary that adds the string version of estimate into "I am {} days old! That's about {} decades!" with the correct values added to it.

age = 22
days = age * 52 * 7
decades = age /10
estimate = round(decades)
summary =  "I Am {days} days old! That's about {estimate} decades ! "

am getting error. What am I missing?

Thanks

You need to use the .format() method on your summary string to put the values into the right places.

Its been 45 mins just figuring out this question. I watched the video 3 times, I didn't understand this question. So I would like to see the correction. Thanks,

Like I said, you need to use .format() on the string. In the videos, we've used placeholders in a string and then passed in values to fill those placeholders. That's exactly what you need to do here.

summary = "Hello {}, I'm {}".format('Hussein', 'Kenneth')

That'll make our summary variable be the string "Hello Hussein, I'm Kenneth".

Thanks for the example. however, am still getting error saying " Your estimate doesn't seem to be in your summary!"

summary = "I Am {} days old! That's about {} decades!" .format('days', 'estimate')

'days' is not the variable days, it's a string. Remove the quote marks from around your variable names.

Not in our course, but codingbat has lots of Python tests. Some of them might be a bit beyond what's in Python Basics, though.
