The contents of your error message looks like this:
In : df.dtypes
This is expected:
In : df[‘vigo’].unique()
Out: array([‘dawson’], dtype=object)
I think the last row is just the character A.
You don’t say how large this dataframe is, but there are tens of thousands of rows so I suspect this is not the issue. You may want to post a sample of the data.
So you want to know why get_dummies() seems to create more columns than you expect.
Here’s a pastebin of the get_dummies() command output. This is the relevant code:
In : grouped = (df[[‘quotes’,’vigo’]].groupby(df[‘vigo’].ne(”).cumsum())
.apply(lambda x: x.to_frame(‘dummies’)))
In : grouped
quotes vigo dummies
