answer:def insert_digit(number, digit, position): Inserts the specified digit into the given position (1-indexed) in the number. Parameters: number (int): The original number. digit (int): The digit to be inserted. position (int): The 1-indexed position where the digit will be inserted. Returns: int: The new number with the digit inserted. num_str = str(number) # If the position is greater than the length of the number, append the digit at the end if position > len(num_str): num_str += str(digit) else: num_str = num_str[:position-1] + str(digit) + num_str[position-1:] return int(num_str)

answer:def sum_of_evens(n): Returns the sum of all even numbers from 1 to n (inclusive). :param n: The upper range of numbers to consider (inclusive). :type n: int :return: The sum of all even numbers from 1 to n. :rtype: int return sum(i for i in range(2, n + 1, 2))

answer:from itertools import chain, combinations def all_subsets_product_except_empty_set(s): Returns the product of elements in all subsets of a set except the empty set. def product(lst): result = 1 for x in lst: result *= x return result # Get all subsets all_subsets = chain.from_iterable(combinations(s, r) for r in range(1, len(s)+1)) # Calculate product of all subsets total_product = 0 for subset in all_subsets: total_product += product(subset) return total_product

answer:def set_intersection(set1, set2): Returns the intersection of two sets without using the built-in intersection method or the & operator. result = set() for element in set1: if element in set2: result.add(element) return result
