Write a Python program to check whether a list contains a sublist.Sample Solution: Python Code:# Define a function named 'is_Sublist' that checks if list 's' is a sublist of list 'l' def is_Sublist(l, s): sub_se
函数首先遍历列表lst中的每个元素,如果某个元素是列表且等于sublist,则返回True。否则,递归调用自身来检查该元素是否包含了sublist,直到遍历完整个列表。 接下来,我们将使用序列图来展示上述方法的执行过程。 序列图 isublistlstisublistlstalt[C is a list]loop[for each element in A]check_list_contains_sublist(A...

This operation allows you to glue together all strings in your list together and return them as a string. Read more here. Note that if your list only contains integers, you should convert the elements to strings before performing the join on them. This is illustrated in the second example ...
()function takes a list of numbers as input. It checks if the list is empty, and if so, it returns 1 as the base case for the recursion. If the list is not empty, it recursively callsproduct_recursive()with the sublist starting from the second element, and multiplies it with the ...

假设我们有一个单词列表和另一个值k。我们必须找到给定单词中恰好包含k个不同单词的子列表的数量。因此,如果输入如下words = [“Kolkata”, “Delhi”, “Delhi”, “Kolkata”] k = 2,那么输出将为5,因为以下子列表具有2个唯一单词:[“Kolkata”,“Delhi”],[“Delhi”,“Kolk...
