I'm confused about the triple quotations making \n in the output. What is it for?

Answer 1

Triple quotes are mostly used as multiline comments, although it's not their real application. Those are string literals, meaning they store a string inside it *exactly* how it is written - kind of a Python replica of the HTML <pre></pre> tag.

Check it out - without those triples I would have to count the spaces and lines and try to fit those string adequately line after line:

Answer 2

triple quotations themselves are showing comment
myVar = 1
'''This is a 1st line of comment
myVar = 42'''
print (myVar)

would print 1

Answer 3

''' stands for a multi line comment
Example:
'''
This is a
Multi line comment
