如何在列表中使用追加？

my_list = [1, 2, 3]
my_list.append(4)
print(my_list)  # 输出：[1, 2, 3, 4]

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> myList = new ArrayList<>();
        myList.add(1);
        myList.add(2);
        myList.add(3);
        myList.add(4);
        System.out.println(myList);  // 输出：[1, 2, 3, 4]
    }
}

#include <iostream>
#include <vector>

int main() {
    std::vector<int> myVector;
    myVector.push_back(1);
    myVector.push_back(2);
    myVector.push_back(3);
    myVector.push_back(4);
    for (int i : myVector) {
        std::cout << i << " ";
    }
    // 输出：1 2 3 4
    return 0;
}
