Changing text

By default you're in Vim's normal mode, meaning that every key press corresponds to a particular command. Hit i on your keyboard to enter an insert mode. This will display -- INSERT -- in a status line (at the bottom), (and, if you're using gVim, it will change the cursor from a block to a vertical line), as can be seen in the following example:

The insert mode behaves just like any other modeless editor. Normally, we wouldn't spend a lot of time in insert mode except for adding new text.

You've already encountered three of Vim's modes: command-line mode, normal mode, and insert mode. This book will cover more modes, see Chapter 3,  Follow the Leader – Plugin Management  for details and explanation.

Let's create our Python application by typing in the following code. We'll be navigating this little snippet throughout this chapter:

To get back to normal mode in Vim, hit Esc on your keyboard. You'll see that -- INSERT -- has disappeared from the status line. Now, Vim is ready to take commands from you again!

The preceding code is not showing Python  best  practices and is provided to illustrate some of Vim's capabilities.
