     Args:
-        condition (Tensor): The condition to choose x or y. When True(nonzero), yield x, otherwise yield y.
+        condition (Tensor): The condition to choose x or y. When True (nonzero), yield x, otherwise yield y.
         x (Tensor|scalar, optional): A Tensor or scalar to choose when the condition is True with data type of float32, float64, int32 or int64. Either both or neither of x and y should be given.
         y (Tensor|scalar, optional): A Tensor or scalar to choose when the condition is False with data type of float32, float64, int32 or int64. Either both or neither of x and y should be given.
         name (str, optional): For details, please refer to :ref:`api_guide_Name`. Generally, no setting is required. Default: None.
