Since the code that you have to write has now increased to more than five lines or so, it has become sufficiently complex to warrant discussing the use of comments. Comments are texts in code that Python ignores, but that explain parts of the code. Comments are not only useful to other people which might need to use or change your code, but also to yourself, as you may need to change your own code some time after you wrote it and you might not remember exactly what you did.

There are two main ways to include comments in Python code. The first is to use a hash mark (#), which turns everything to the right of the hash mark on the line into commentary (of course, this is only the case if the hash mark is not part of a string). The second is to use triple double-quotes or triple single-quotes to indicate the start and end of some commentary, which may be spread over multiple lines. In this case, the starting triple quotes should always be at the start of a line, and you cannot use this way of commenting in an indented code block. The reason is that you are basically placing a multi-line string in your code.

Learn more about comments by studying the code below.

# comment: insert your code here.
# BTW: Have you noticed that everything right of the hash mark 
print( "Something..." ) # is ignored by your python interpreter?
print( "and something else.." ) # Use this to comment your code!
"""Another way of commenting on your code is via triple quotes 
-- these can be distributed over multiple """ # lines
'''which can also be done with single quotes''' # but be careful 
# with there being quotes IN your comments when you use this 
# multi-line method
print( "Done." )
