+
+        Take elements at indices 0 and 3 along the axis 0 (default)
+
+        >>> df.take([0, 3])
+        0  falcon    bird      389.0
+        3  monkey  mammal        NaN

+        Take elements at indices 1 and 2 along the axis 1
+

+        Also, we may take elements using negative integers for pos indices
