- In Python, if you want to create a list with duplicate elements, it's super easy. For example, if you want a list of five 'hello's, you can just do ['hello'] * 5. It's like getting five identical presents all at once! - Python里啊,如果想创建有重复元素的列表,那可太简单了...
Write a Python program to find the first duplicate element in a given array of integers. Return -1 if there are no such elements.Sample Solution:Python Code :def find_first_duplicate(nums): num_set = set() no_duplicate = -1 for i in range(len(nums)): if nums[i] in num_set: re...

We can also use the counter() method to check if a list has only unique elements or not. The counter() method. The counter() method takes an iterable object as an input and returns apython dictionaryin which the keys consist of the elements of the iterable object and the values associat...
python def duplicate(lst): unique_elements = set() new_lst = [] for element in lst: if element not in unique_elements: unique_elements.add(element) new_lst.append(element) return new_lst 现在,我们已经完成了一个能够识别和剔除重复元素的函数。我们可以通过调用该函数,并传入一个列表来测试它的...

In the below example we first tokenize the sentence into words. Then we apply set() function which creates an unordered collection of unique elements. The result has unique words which are not ordered. import nltk word_data = "The Sky is blue also the ocean is blue also Rainbow has a ...
to articulate it more effectively, each entry in the initial array can be viewed as a distinct dimension. For example, if there are two elements in the array, the values 0 and 1 can be assigned; if there are three elements, then the values 0, 1, and 2 can be assigned, and so on...
