Answer
There’s no ambiguity here. file
is a dataframe, and dtypes
is an attribute.
df productView order userId A 4.5 5.0 B 1.5 2.5 C 4.0 2.0 D 2.0 3.0 df.dtypes productView float64 order float64 dtype: object
When you access dtypes
, a Series is returned:
type(df.dtypes) pandas.core.series.Series
When you call df.dtypes()
, you are effectively doing series = df.dtype; series()
which is invalid, since series
is an object (not a function, or an object with __call__
defined).
In the second case, dtype
isn’t even a valid attribute/method of df
, and so an AttributeError
is raised.
TLDR; The first error is raised on the dtype
series, the second is raised on the original dataframe df
.
