Error when getting column values of a Pandas dataframe after doing row sums

Question

For this dataframe:

t = pd.DataFrame({'a':np.random.randint(1,9,10), 'b':np.random.randint(1,9,10)})

I am trying to create a new columns by doing sum of each row:

t['sum'] = t.sum(axis=1)

but, when I try to retrieve the values by: t.sum.values I get the following error: AttributeError: 'function' object has no attribute 'values'

However, if I just sum the two columns manually t['sum2'] = t.a + t.b I can then get the column value by t.sum2.values without error. Can somebody explain to me what I have done wrong?

Cause sum is build in function for pandas

You should call the columns with

t['sum'].values

Rather than

t.sum.values#(wrong)
