Function Junction (Optional comment)

#1 
Hi, guys, I'd like to know, why should I live a (optional comment)
after the function? 
Is it a must? cheers.

def spam():
"""Print 'Eggs!' to the console"""        <<<<<<<---
print 'Eggs!'

spam()```
#2

Edit: Oh wait, you meant the triple quotations

That for making a multi line comment

#3 
def spam():
    """Print 'Eggs!' to the console"""
    print 'Eggs!'

spam()

When the docstring is written as the first line in a function it is reachable.

>>> def spam():
    """Print 'Eggs!' to the console"""
    print ('Eggs!')

    
>>> def get_spam_docs():
	print (spam.__doc__)

	
>>> get_spam_docs()
Print 'Eggs!' to the console
>>>

That’s not something we would actually do in a program, but rather in the inspection and documentation of the larger application.
