why we need backlash after "a"?

Hey Christine,

Thank you for reaching out!

The backslash after the letter 'a' helps moving the rest of the sentence on a new line (otherwise it becomes very long and hard to read).

Consider the following cases:

1. Correctly moving the code to a new line using a backslash. Note that you shouldn't have any characters on the first line after the backslah (even spaces). Otherwise, the code will return a syntax error.

2. Writing the code on a single line but leaving the backslash - here, we've introduced an unwanted backslash in the output:

3. Writing the code on a single line and removing the backslash between 'a' and 'fish' - this produces the same output as the one shown by Giles (case 1 above).

4. Moving the code to a new line without adding a backslash - this produces an error as we've moved the code to a new line incorrectly.

Hope this helps!

Kind regards,
