> >>> pd.Series([1, 2, np.nan], dtype=float).astype(bool)
> >>> pd.Series([1, 2, np.nan], dtype=str).astype(bool)
> >>> pd.Series([datetime.date(1994, 1, 31), datetime.date(1994, 2, 1), np.nan])
> 0     True
> 1     True
> 2     True
> dtype: bool
> But in pyspark, it is:
> 0     True
> 1     True
> 2     False
> dtype: bool
