Comments are usually added to projects to explain what a programmer wanted parts of the program to do. Comments are helpful when collaborating and troubleshooting, as they document what the code does without having to reread and comprehend many lines of code. Other programmers can read the comments to understand the code's functionality, and the original programmer can remember what their code does after revisiting a project.
Python Comments
All comments in Python start with a # (pound) symbol.
Type any text, numbers, or symbols after the # (pound) sign. Comments typically describe the functionality of the code to help the programmer understand what a piece of code does.
When the comment is complete, press the "Enter" or "Return" key to go to the next line. Comments only span one line.
