Create dummy variables and display the new shape of your data frame.

We're creating a new definition for the investor data dataframe, using the Pandas get dummies function, and then passing at the argument investor data, our old dataframe to verify that was done correctly. We're displaying the investor data shape attribute, and when you execute that sell, you'll see that you still have 7,233 observations, but now you have 21 features instead of 11.
