You can include rich-text code descriptions of your code by entering and formatting the text in a Markdown cell.<br/>\n\nMarkdown cells allow us to apply several formatting options with the Markdown language: \n\n* Headings\n* Links\n* Tables\n* Paragraphs\n* Bold text\n* Lists\n* And more\n\n</div>\n\n",

Not only does this help <strong>other people</strong> understand your code, but it can also serve as a reminder <strong>to you</strong> when you come back to it weeks or months later.</p>\n\n<p>\n     To write comments in Python, use the number symbol <code>#</code> before writing your comment.
