## Comments in Vyper We're going to talk about comments in Vyper. This little hashtag here is, or pound symbol, makes this whole line here, what's known as a comment. ```python # pragma version 0.4.0 ``` And typically, a comment is a line in your code where you can write pretty much whatever you want, and the compiler will ignore it. The compiler doesn't ignore these lines if it sees a comment. ```python # asdfagolsa asdfasrtafdsdf ``` We can also use comments to leave ourselves notes, like this: ```python # This is how we tell the Vyper compiler # what version to use # pragma version 0.4.0 ``` We can also copy and paste these comments into a text editor or a notes app so that we can refer to them later. It is important to save our work frequently, because if we lose our tab, we'll lose all of our text.
