[已解决]我的代码出现什么问题，求大神解答

小甲鱼讲的python第12讲课后题的第五题


这是那一题的例子>>> list1 = [x**2 for x in range(10)]
                          >>> list1
                           [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]


               改写为  list1 = []
                           for x in range(10):
                           list1.append(x**2)

这是题目>>> list1 = [(x, y) for x in range(10) for y in range(10) if x%2==0 if y%2!=0]

这是我的代码，
list1=[]
for x in range(10):
    if x%2==0:
        for y in range(10):
            if y%2!=0:
                list1.append((x,y))
                print(list1)
但输出却一直再重复

改为：

1. list1=[]
   
2. for x in range(10):
   
3.     if x%2==0:
   
4.         for y in range(10):
   
5.             if y%2!=0:
   
6.                 list1.append((x,y))
   
7. print(list1)
