第一题

L1 = [] for num in range(1, 10000): factors = [] for i in range(1, num): if num % i == 0: factors.append(i) if sum(factors) == num: L1.append(num)

第二题

L2 = [] for num in range(100, 1000): digit1 = num // 100 digit2 = (num % 100) // 10 digit3 = num % 10 if digit13 + digit23 + digit3**3 == num: L2.append(num)

第三题

L3 = [] for num in range(300, 501): if str(num) == str(num)[::-1]: is_prime = True for i in range(2, int(num**0.5)+1): if num % i == 0: is_prime = False break if is_prime: L3.append(num
