to our customers. The way we want do that is to use PD merge. Take a look at what this is telling us.
0:25
Is joining emerging The customers in the states and then left on and right on are telling us that state and state code are essentially the same values.

And that's what we want to use to merge the two data frames together. We do need to make sure we actually assigned this to a variable.

So we're gonna call this customer. We have to state columns, state code and state. So we're gonna drop one of those.

worked as expected. So we saw 50 values, which is what we would expect now the final pieces we need to bring our sales rep it so can do another merge.

and we're also gonna drop the extra region. Now, if we look at our data frame, we have each customer. We have the city and state.
