import numpy as np def remove_duplicates(arr): return np.unique(arr) 示例 arr = np.array([1, 2, 2, 3, 4, 4, 5]) print(remove_duplicates(arr)) # 输出: [1 2 3 4 5] 六、使用Pandas库 Pandas库也提供了方便的方法来去除重复项,特别是当处理数据框时。 步骤: 使用pandas.Series的unique...
import numpy as np def remove_duplicates_with_numpy(arr): return list(np.unique(arr)) 示例 arr = [ 1, 2, 3, 1, 2, 4, 5] result = remove_duplicates_with_numpy(arr) print(result) # 输出:[1, 2, 3, 4, 5] 具体步骤: 使用numpy.unique函数对数组进行去重。 将结果转换为列表。 这...
5. 方法四:使用numpy(仅适用于数值类型) 如果你在处理数值型数组时,可以使用numpy库,该库提供了非常方便的操作。 importnumpyasnpdefremove_duplicates_with_numpy(arr):returnnp.unique(arr)# 示例sample_array=np.array([1,2,3,1,2,3,4])unique_array=remove_duplicates_with_numpy(sample_array)print(uniq...
return_inverse = If True, also returns the indices of unique array axis = Axis 0 represents rows and axis 1 represents columns, if no axis is provided then the input array will be flattened i.e treated as a 1d array 1. 2. 3. 4. 5. 6. 7. 从一维 NumPy 数组中删除重复元素 方法: ...
如上所示，利用np.unique()数据元素已去重。并返回numpy.ndarray。ps:numpy.unique()函数扩展 numpy....
Another popular third-party library isNumPy, which also offers a solution to remove duplicates. NumPy can be installed usingpipor other package managers: $ pipinstallnumpy NumPy'sunique()function returns a NumPy array with the unique elements from its argument. This NumPy array can be converted ...

2、数组array/numpy 笔者目前见到的排序有以下几类:sort、sorted;argsort返回的是数列排序的秩 sort+sorted跟之前的元组、list一样,但是argsort不太一样。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>b=np.array([1,6,42,7,4,3,8,9,3])>>>b.sort()>>>barray([1,3,3,4,6,7,8,9...
