Tell us what’s happening:

I don’t know how to tell what it is saying is wrong in the console(F12). It is on the last portion, and everything looks the same except at the end it shows - t then on the next line ? ^ and then the same thing but on the same line.

Your code so far

An assertion error gives you a lot of information to track down a problem. For example:

AssertionError: 'Year' != 'Years'
- Year
+ Years
?     +

Your output comes first, and the output that the test expects is second.

AssertionError: ‘Year’ != ‘Years’

Your output: Year does not equal what’s expected: Years

- Year
+ Years
?     +

- Dash indicates the incorrect output
+ Plus shows what it should be
? The Question mark line indicates the place of the character that’s different between the two lines. Here a + is placed under the missing s .

I hope this helps interpret your error!

You can see your assertion error here:

AssertionError: 'Perc[226 chars]F  E \n     u  o  n \n     s  o  t \n     i  d[137 chars]t \n' != 'Perc[226 chars]F  E  \n     u  o  n  \n     s  o  t  \n     i[148 chars] t  '

It helps to break it up into two lines like this to compare

AssertionError: 
'Perc[226 chars]F  E \n     u  o  n \n     s  o  t \n     i  d[137 chars]t \n' != 
'Perc[226 chars]F  E  \n     u  o  n  \n     s  o  t  \n     i[148 chars] t  '

Your output comes first, and the output that the test expects is second.

That helped a ton, thanks
