code: def _safe_reshape(arr, new_shape):
      
      if isinstance(arr, ABCSeries):
          arr = arr._values
      if not isinstance(arr, ABCExtensionArray):
          arr = arr.reshape(new_shape)
      return arr
docs: If possible, reshape `arr` to have shape `new_shape`,
      with a couple of exceptions (see gh-13012):
  
      1) If `arr` is a ExtensionArray or Index, `arr` will be
         returned as is.
      2) If `arr` is a Series, the `_values` attribute will
         be reshaped and returned.
  
      Parameters
      ----------
      arr : array-like, object to be reshaped
      new_shape : int or tuple of ints, the new shape
