8. Return a New List with Distinct Elements from a List Write a Python function that takes a list and returns a new list with distinct elements from the first list. Sample Solution: Python Code: # Define a func
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...
import numpy as np arr = np.array([1, 2, 2, 3, 4, 4, 5]) unique_arr, indices = np.unique(arr, return_index=True) print("Unique array:", unique_arr) print("Indices of unique elements in original array:", indices) R语言中的unique函数在R语言中,unique函数用于去除向量、矩阵或数据...
Sample Solution: Python Code: # Define a function 'unique_product' that calculates the product of unique elements in a listdefunique_product(list_data):# Create a set 'temp' to store unique elements in the listtemp=list(set(list_data))# Initialize a variable 'p' to store the product and...
In Dart, Set is a collection of unique elements. It does not allow duplicate values and provides efficient membership testing operations. Set implements the Iterable interface and provides methods for mathematical set operations like union, intersection, and difference. Elements must have consistent ...
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...
The NumPy unique function in Python is used to find and return theunique elementsfrom an array. When called on an array, it returns another array containing only the distinct values, with duplicates removed. MY LATEST VIDEOS This function is extremely useful when: ...
