Cantor函数从java翻译成Python

Question

我在java中编写了一个cantor函数，我试图将其转换为Python。谁能给我一些指示？我应该将分数作为一个变量进行比较，还是将顶部和底部视为单独​​的变量？

的java：

    import java.util.Scanner;
    public class asdf {
     public static void main(String[] args){
    Scanner keyboard = new Scanner(System.in);
    System.out.println("ENter the nth ratio you want: ");
    int end = keyboard.nextInt();
    int count = 0;
    int top = 0;
    int bottom = 0;
    boolean flip = true;
    for(int i=0; i<end; i++){
        if(flip){
            top = i+1;
            bottom = 1;
            for(int j = 0; j<i+1; j++){
                if(count == end){
                    break;
                }
                System.out.println(top + "/" + bottom);
                top--;
                bottom++;
                count++;
            }
            flip = false;
        }
        else{
            top = 1;
            bottom = i+1;
            for(int j = 0; j<i+1; j++){
                if(count == end){
                    break;
                }
                System.out.println(top + "/" + bottom);
                top++;
                bottom--;
                count++;
                flip = true;
            }
        }
    }
}
    }

Python：

    def cantor(dat):
    n=len(dat)
    count, top, bottom = 0,0,0
    boolean flip = true
    for i in range (0,x):
            if (flip):
                    top = i+1
                    bottom = 1
                    for j in range(0,top):
                            if count == 21: break
                            boolean found = false
                            double temp = top*1.0/bottom
                            for k in range(0,n)):
                                    if temp == n[k]:
                                            found = true
                                            break
                    if !
         top = top-1
         bottom = bottom+1
         count = count+1
