[已解决]大佬们，这个结果为什么是这样的啊

hujiezhong

        list1 = [(x, y) for x in range(10) for y in range(10) if x%2==0 if y%2!=0]
>>> lsit1
[123, 456]
大佬们，我的思考是这样的，因为x%2 == 0是偶数， y%2 != 0是奇数.
所以x为0到9之间的所有偶数，y为0到9之间的所有奇数,但是结果是[123, 456]是真没想到.
各位大佬能解决这个吗，求解。
拜托了!

1. list1 = [(x, y) for x in range(10) for y in range(10) if x % 2 == 0 if y % 2 != 0]
   
2. 
   
3. list2 = []
   
4. for x in range(10):
   
5.     for y in range(10):
   
6.         if x % 2 == 0 and y % 2 != 0:
   
7.             list2.append((x, y))
   
8. print(list1)
   
9. print(list2)

拆来开，结果是这样的：
[(0, 1), (0, 3), (0, 5), (0, 7), (0, 9), (2, 1), (2, 3), (2, 5), (2, 7), (2, 9), (4, 1), (4, 3), (4, 5), (4, 7), (4, 9), (6, 1), (6, 3), (6, 5), (6, 7), (6, 9), (8, 1), (8, 3), (8, 5), (8, 7), (8, 9)]
[(0, 1), (0, 3), (0, 5), (0, 7), (0, 9), (2, 1), (2, 3), (2, 5), (2, 7), (2, 9), (4, 1), (4, 3), (4, 5), (4, 7), (4, 9), (6, 1), (6, 3), (6, 5), (6, 7), (6, 9), (8, 1), (8, 3), (8, 5), (8, 7), (8, 9)]
