summary part of changing days into string

How do I do the last part of summary = "I am {} days old!" I changed it to "I am {} days old!".format(days) "I am {} days old!".format(str=days) and a few other ways but to no use. Can anyone help out? thanks!

days_alive.py 
age = 27
days = age * 52 * 7
summary = "I am {} days old!"

It is about formatting string.

There are several ways to do this but what you are taught is probably using format() function.

It works as follow.

The placeholder in a string will be substituted by arguments in format() function.

Simplest placeholder is pair of bracket {}. Using placeholder in this way makes it positional placeholder.

The number of argument has to match with number of placeholder (in simplest form)

For example,

my_string = '{} {}'
a = hello
b = world

my_string.format(a, b) # ''hello world"

So to apply this logic to question.

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

You said you did "I am {} days old!".format(days) there is no reason why this shouldn't work.

I will try again and see. But i'm fairly certain I did this a few times and it didn't work.

Here's my passed code while trying to solve your issue.

age = 27
days = age * 52 * 7
summary = "I am {} days old!".format(days)

If the question didn't pass please let me know what the grader said.

It could be small typo or connection issue but you get the idea that's all it matters.
