Introduction to Python(Comments)

Here I will start with python comments.

Comments are useful everywhere in programs.It helps us to know about what the line really specifies.
It depends on  how we use it and where we use it.
But nowdays programmers don't use it because they don't want to reveal their algorithms.
Someone said it:
      It's harder to read code then to write it.

# this is our first comment
PP = 1  # and this is the second comment
          # ... and now a third!
PP1 = "# This is not a comment because it's inside quotes."
