In programming, comments are the parts of code that Python ignores. The primary purpose of using them is readability. It is good practice to leave comments in your code with descriptions of what a particular part of that code does.

In Python, the comment starts with the hash # sign. All the text to the right of the # will be ignored. For example, you may have two print() functions, but if you place # to the left of one of them, then only one text will be outputted.
