age = int(22)
days = int((age*52)*7)
summary = ("I am " + {days} + " days old!")

Hi Andy,

Variables in python don't need any characters around them, so if you want to concatenate two string together where one of the is stored in a variable, you can do so like this:

my_string = "house"
bigger_string = "tree" + my_string

In Python, the '{' and '}' characters are used to create "dictionaries", which have a specific syntax that needs to be used. Your code won't pass because python is looking for some extra information along with those curly braces.

Try one of the following:

1.

summary = "I am " + str(days) + " days old!"

or

2.

summary = "I am {} days old!".format(days)

The reason why your coding isn't working is because you're trying to concatenate a string with a set.
