Reconstruct the input array from the unique values: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>a=np.array([1,2,6,4,2,3,2])>>>u,indices=np.unique(a,return_inverse=True)>>>uarray([1,2,3,4,6])>>>indicesarray([0,1,4,...,1,2,1])>>>u[indices]array([1,2,6...
Option 3: UsingSet()# TheSetobject is a newer addition to JavaScript that lets you store unique values. Each value in aSetcan only appear once.You can use it to remove duplicates from arrays. Just like our last attempt, we’ll use theString.prototype.split()method to convert our string...
