Python Python 中没有内置的 unique 函数,但你可以使用集合(set)来去除重复项,或者使用字典保持元素的顺序。 使用集合(不保证顺序): def unique_elements(lst): return list(set(lst)) # 示例 print(unique_elements([1, 2, 2, 3, 4, 4, 5])) # 输出: [1, 2, 3, 4, 5] 使用有序字典(保留...
python import numpy as np # 假设原数组为a a = np.array([0, 1, 2, 0, 3, 4, 0, 5]) # 使用布尔索引去除0值 a_filtered = a[a != 0] # 使用unique函数去除剩余元素中的重复值 unique_elements = np.unique(a_filtered) print("去除0值后的数组:", a_filtered) print("去除0值并去重...
To get unique values in an array, we can use the NumPy unique function in Python. This identifies elements in an array, with options for additional functionality. Its basic use returns sorted unique values, but parameters like return_index, return_inverse, and return_counts provide indices, inv...
Find the unique elements of an array. Returns the sorted unique elements of an array. There are three optional outputs in addition to the unique elements: the indices of the input array that give the unique values the indices of the unique array that reconstruct the input array ...
