### Question

In the context of this exercise, is a left merge just a right merge but switching the order of the dataframes?

### Answer

Yes, a left merge is the reverse of a right merge, and you can essentially perform either by switching the order of dataframes and using the other type of merge.

For example, these will produce the same results.

`df1.merge(df2, how='left')`

and

`df2.merge(df1, how='right')`

The only difference would be the order of the resulting dataframe, for the columns and for the rows which will preserve the order of the left keys.
