I actually wasnt able to understand this part. Can anybody explain it to me more easily?

Answer 1

It means you need to use this \ slash for some special characters.
Like to put the apostrophe in the code it used this \ to print.
similarly to print next line you have to use \n as we use "enter"key

eg: print("Sorry Johnny\n This explanation may help you.")

Answer 2

It says that whether you put single quote ' or double " quote for printing the string. it does not affect the output of the string.
print('pink')
will give same output as
print("pink")

Answer 3

I was actually talking about the third lesson.
The one about new lines.

Answer 4

Yeah!! I got it.
Thank you
