days_alive.py Task 1 no longer working

I can complete task 1 and 2, but when I attempt to make the summary variable I get a message saying task 1 is no longer working. I'm not sure if it is my attempt at the summary variable that is breaking it or not.

Sometimes the validation is a stickler. Your string has an extra space after the 'old!' Try removing the space.

This code worked for me:

age = 40
days = age * 52 * 7
summary = ("I am {} days old"
           "".format(days))

Note: the above code was added using an iPhone. With the narrow screen, I had to aggressively wrap my lines!

It would help to post your code. When you see "task 1 is no longer working" it can mean a syntax error has been introduced. Use the "Return to task 1" to run the failing code in task 1. If no return button is present, copy your current task 2 solution and reload the page to get back to task1.

age = 25
days = (age * 52) * 7
summary = ("I am {} days old! ".format(days))

This passes for me. Are you still getting a Bummer message?

I had to remake my account, didn't know I get a company discount ;)

It passed when I made my way back to this section and entered the text again.

I am little confused why we have to put .format(days) I think it has to do with {} that I am confused about it's part of the string are we using that to cal days?

The .format() isn't strictly required by Python, the challenge asks for it because it's good style.

As a beginner, you could have build up the string using the less favored string addition

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

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

# there is also the old % format - Don't use (revisit when you get to python logging)
summary = "I am %s days old!" % days

The {} is a replacement field marker used by .format(). Each field is replaced with items in the .format() argument list. Some examples can be found here
