Python Pandas - Create column & add stings?

[craptakular]

Hi there,

I'm playing about with Python and pandas.

I have a column called 'County' but I need to create a column called 'Region' and populate it like this (atleast I think):

If County column == 'Suffolk' or 'Norfolk' or 'Essex' then in Region column insert 'East Anglia'

If County column == 'Kent' or 'East Sussex' or 'West Sussex' then in Region Column insert 'South East'

If County column == 'Dorset' or 'Devon' or 'Cornwall' then in Region Column insert 'South West'

So far I have this:

myDataFrame['Region'] = np.where(myDataFrame['County']=='Suffolk', 'East Anglia', '')

But I suspect this won't work for any other counties

As I'm sure is obvious I am a beginner.

Hope people can help a noob!
