-#### 💡 Explanation:
-* For 1, the correct statement for expected behavior is `x, y = (0, 1) if True else (None, None)`.
-* For 2, the correct statement for expected behavior is `t = ('one',)` or `t = 'one',` (missing comma) otherwise the interpreter considers `t` to be a `str` and iterates over it character by character.
-* `()` is a special token and denotes empty `tuple`.
+#### 💡 说明:
+* 对于 1, 正确的语句是 `x, y = (0, 1) if True else (None, None)`.
+* 对于 2, 正确的语句是 `t = ('one',)` 或者 `t = 'one',` (缺少逗号) 否则解释器会认为 `t` 是一个字符串, 并逐个字符对其进行迭代.
+* `()` 是一个特殊的标记，表示空元组.
