Coding: Introduction to Python v3, topic 4.2.1
Comments
Comments are lines of code that are ignored completely by the computer.
What are comments?
- A comment is a line of code that is completely ignored by the computer.
- Comments can be used to add description to your code to make it easier for other people to understand.
- They can also be used to leave notes and reminders to yourself as you work on a complex program.
How to comment
- To write a comment in most languages, you must use a special character which tells the computer to ignore the rest of the line:
- In Python, that character is a #.
Interfaces
- An interface is a collection of comments which describe a subroutine.
- An interface includes:
- List of parameters and their types.
- Return value and its type.
- What the subroutine does.
