Commenting Code and Comment Tips

Comments are key to ensuring that your code is easy to follow and speeds up maintaining and checking.  There are two methods to creating comments in your code.

Line Comments

Line comments start with a harsh (#), this tells the python interpreter to skip over this line, continuing on the next line.

# Usefult comment here
print 'hello world!'

Block Comments

Block comments are initiated with three quotation marks in a row ("""), this tells the python interpreter to skip the code until it reaches three quotation marks in a row (""") again.


""" Many lines
of usefult comments
here """
print 'hello world!'

When commenting code it is import to include a useful amount of detail, too many or too few comments can both have negative impacts on readability.
