Consider the series s s = pd.Series([(1, 2), (3, 4), (5, 6)]) This is as expected s == (3, 4) 0 False 1 True 2 False dtype: bool This is not s.eq((3, 4)) --------------------------------------------------------------------------- ValueError Traceback (most recent call last) ValueError: Lengths must be equal I was under the assumption they were the same. What is the difference between them? What does the documentation say? Equivalent to series == other, but with support to substitute a fill_value for missing data in one of the inputs.
