question:Write a Python program to shuffle the items of a given list in random order without using the built-in shuffle function from the random module.
answer:import random def shuffle_list(arr): Shuffle the items of a given list in random order. Parameters: arr (list): The list to be shuffled. Returns: list: The list after being shuffled. arr_copy = arr[:] length = len(arr_copy) for i in range(length): j = random.randint(0, length - 1) arr_copy[i], arr_copy[j] = arr_copy[j], arr_copy[i] return arr_copy
question:I have just started learning Python. Can you provide me an easy example of a nested function in Python?
answer:def outer_function(x): Outer function that takes one argument x. def inner_function(y): Inner function that takes one argument y. return x + y return inner_function
question:Construct a function that will calculate the symmetric difference (elements that are in one set but not in the other and vice versa) of multiple provided sets. Your solution should be robust enough to handle an arbitrary number of sets, and also consider the repetition of elements, if any, in the given sets. After finding the symmetric difference, elements should maintain their original order as they were in the initial sets. Also, implement a way to remove any duplicates that might result in the final symmetric difference.
answer:def symmetric_difference(*sets): Returns the symmetric difference of multiple given sets. The symmetric difference are elements that are in one set but not in the others, excluding any duplicates. result = set() for s in sets: result ^= set(s) # Preserve the original order and remove any duplicates seen = set() final_result = [] for s in sets: for elem in s: if elem in result and elem not in seen: final_result.append(elem) seen.add(elem) return final_result
question:How can I implement a function that finds the index of the smallest element in a given list? Can you provide an example code that accomplishes this?
answer:def find_index_of_smallest_element(lst): Returns the index of the smallest element in the list. if not lst: return None min_index = 0 for i in range(1, len(lst)): if lst[i] < lst[min_index]: min_index = i return min_index
