AttributeError: 'NoneType' object has no attribute 'drop'

Question

I'm trying to remove some columns from my dataframe, however I'm just getting this error no matter how hard I try to figure out how to fix it. Could you help me?

drop_cols = ['ISO3A código economía declarante',
 'ISO3A código economía asociada',
 'Código metadatos del valor',
 'Metadatos del valor',
 'Valor (no numérico)']

data = data.drop([drop_cols], axis=1)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-58-0d59600c7b98> in <module>
----> 1 data = data.drop([drop_cols], axis=1)

AttributeError: 'NoneType' object has no attribute 'drop'

I also used inplace = True and it didn't work for me either

The error likely means that `data` is None. Not `drop_cols` What is `data` before the snippet? — 2ps, Nov 21 '20 at 05:42
What is the output of `type(data)` if you add that just before the line that triggers the error? — Ben, Nov 28 '20 at 01:28

Besides, this answer doesn't work. It is contradictory to specify `inplace=True` and to expect a new dataframe to be returned. – chrslg Nov 01 '22 at 20:47
