如何从列表中选择多组元素

my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
selected_elements = []

for element in my_list:
    if element % 2 == 0:  # 选择偶数
        selected_elements.append(element)

print(selected_elements)  # 输出: [2, 4, 6, 8]

my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
selected_elements = [element for element in my_list if element % 2 == 0]

print(selected_elements)  # 输出: [2, 4, 6, 8]

my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
selected_elements = list(filter(lambda x: x % 2 == 0, my_list))

print(selected_elements)  **输出: [2, 4, 6, 8]**

SELECT * FROM my_table WHERE condition = 'value';

const myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const selectedElements = myArray.filter(element => element % 2 === 0);

console.log(selectedElements);  // 输出: [2, 4, 6, 8]
