In this Python blog, I will explainhow to get unique values in an array using the NumPy unique function in Python. I will explain different use cases for the NumPy unique function likenp.uniquewithout sorting, NumPy unique with tolerance, etc. To get unique values in an array, we can use...
python的array数组中,常用函数有一个函数有锁种用法,根据返回参数的不同,保留数组中不同的值,那就是np.unique函数。本文介绍python中np.unique的两种使用方法:1、对于一维数组或者列表去重并按元素由大到小返回一个新的无元素重复的元组或者列表;2、返回新列表元素在旧列表中的位置,并以列表形式储存在s中。 使用...
print(np.unique(a,return_inverse=True)) # (array([1, 2, 3, 4, 5]), array([0, 4, 3, 1, 2, 2, 4])) # 返回该元素在list中出现的次数 print(np.unique(a,return_counts=True)) # (array([1, 2, 3, 4, 5]), array([1, 1, 2, 1, 2])) # 当加参数时,unique()返回的是...
a = np.array([1,2,4,4,5,2]) d = da.from_array(a, chunks=(3,)) r_a = np.unique(a, **kwargs) r_d = da.unique(d, **kwargs)ifnotany([return_index, return_inverse, return_counts]):assertisinstance(r_a, np.ndarray)assertisinstance(r_d, da.Array) r_a = (r_a,) r...
EXAMPLE 1: Get unique values from a 1D Numpy array First, let’s get get the unique values from our 1D array,array_with_duplicates. # GET UNIQUE VALUES np.unique(array_with_duplicates) OUT: array([1, 3, 4, 5]) Explanation This is pretty simple. ...
Python program to concatenate two arrays and extract unique values# Import numpy import numpy as np # Creating numpy arrays arr1 = np.array([-1, 0, 1]) arr2 = np.array([-2, 0, 2]) # Display original arrays print("Original array 1:\n", arr1, "\n") print("Original array 2:...
unique: The sorted unique elements of the array. unique_indices (Optional): Indices of the first occurrences of the unique values in the original array. Returned if return_index is True. unique_inverse (Optional): Indices to reconstruct the original array from the unique array. Returned if ret...
