-- **axis**: _Optional\[ int, Tuple\[ int ] ]_ 
+- **axis**: _Optional\[ Union\[ int, Tuple\[ int, ... ] ] ]_ 
 
  - axis (or axes) along which to flip. If `axis` is `None`, the function must flip all input array axes. If `axis` is negative, the function must count from the last dimension. If provided more than one axis, the function must flip only the specified axes. Default: `None`.
 
 #### Returns
 
 - **out**: _<array>_
 
- - an output array having the same data type as `x` and whose axes, relative to `x`, are flipped.

+
+Reshapes an array without changing its data.
+
+#### Parameters
+
+- **x**: _&lt;array&gt;_
+
+ - input array to reshape.
+
+- **shape**: _Union\[ int, Tuple\[ int, ... ] ]_ 
+
+ - a new shape compatible with the original shape. If `shape` is an integer, then the result must be a one-dimensional array of that length. One shape dimension is allowed to be `-1`. When a shape dimension is `-1`, the corresponding output array shape dimension must be inferred from the length of the array and the remaining dimensions.
+
+#### Returns
+
+- **out**: _&lt;array&gt;_
+
+ - an output array having the same data type, elements, and underlying element order as `x`.
