首先，‘and’、‘or’和‘not’的优先级是not>and>or。(逻辑运算符）

>>> print(9 or 2)
9
>>> print(6 or 2>1)
6
>>> print(0 or 5<4)
False
>>> print(2>1 or 6)
True
>>> print(3 and 2>1)
True
>>> print(0 and 3>1)
0
>>> print(0 and 3)
0
>>> print(2>1 and 3)
3
>>> print(3>1 and 0)
>>> print(1>1 or 3<4 or 4 >5 and 2>1 and 9>8 or 7<6)
True
>>> print(not 2>1)
False
>>> print(not 2>1 and 3<4 or 4>5 and 2>1 and 9>8 or 7<6)
False
