Try using the dir method on integers and floats. 0)). Are there methods you didn’t expect? As you can see, dir gives you insight into the built-in methods for each Python data type; these methods can prove valuable when wrangling data using Python. We rec‐ ommend taking time to experiment with the listed methods that interest you and testing more methods with different data types. info help The third helpful built-in Python method we will review in this chapter is the help method. This method will return the documentation for an object, method, or mod‐ ule—although it is often written in a very technical (sometimes cryptic) manner.
Info | 35 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill'] If you look at the string 'cat,dog,horse', it looks like it is a list saved in a string. split(',') Python will return a list: ['cat', 'dog', 'horse'] Now let’s call the dir method on our list: dir(['cat', 'dog', 'horse']) There are not as many options as for strings, but let’s try a few. First, let’s turn the list into a variable. sort() After you run each of those lines, print out the value of animals so you can see how the the method has modified the list.
Another completely free and cross-platform text editor is Atom. Some people are particular about their code editors. While you do not have to use the editors we recommend, we suggest avoiding Vim, Vi, or Emacs unless you are already using these tools. Some programming purists use these tools exclusively for their code (one of the authors among them), because they can navigate the editor com‐ pletely by keyboard. However, if you choose one of these editors without having any experience with it, you’ll likely have trouble making it through this book as you’ll be learning two things at once.
