for num in range(1, n + 1):
    if num % 2 == 0 and num % 3 != 0:
        print(num)

答案正确

c++：

#include<bits/stdc++.h>

using namespace std;
int main(){
	int n;
	cin>>n;
	for(int i=1;i<=n;i++){
		if(i%2==0 and i%3!=0){
			cout<<i<<endl;
		}
	}
	return 0;
}`

n=int(input())
i=2
while i<=n:
    if i%2==0 and i%3!=0:
        print(i)
        i=i+2
    else:
        i=i+2
