How to fix "KeyError" when extracting value from pandas series

Question

I'm extracting values from a pandas series. The column data type is object. Everything up to creating the series if OK, but extracting a value from the series generates a KeyError. What am I missing?

Created a dataframe from a csv file and generated a series

migrants.info()
<class 'pandas.core.frame.DataFrame'>
Int64Index: 6459 entries, 1 to 716
Data columns (total 6 columns):

```
area         6459 non-null object
```
dtypes: int64(1), object(5)
memory usage: 513.2+ KB


migrants_area = migrants["area"]
type(migrants_area)
pandas.core.series.Series

migrants_europe = migrants_area["Europe"]

I expect the output to be all occurrences of "Europe" from the series
