bookComments

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

In Python, the comment starts with the hash # sign. All the text right to 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 output.
