python逻辑运算符中not,and,or的优先级比较

 1 >>> a=3
 2 >>> b=4
 3 >>> c=5
 4 >>> d=6
 5 >>> c>d and b>a or d>c
 6 True
 7 ‘’‘>>> c>d and b>a not c>d
 8   File "<stdin>", line 1
 9     c>d and b>a not c>d
10                     ^
11 SyntaxError: invalid syntax’‘’
12 >>> c>d and b>a or  not c>d
13 True
14 >>> c>d and b>a or not d>c
15 False
16 >>>

由上所述,逻辑运算符中的优先级为not>and>or

不过一般写代码时最好不要这样写,尽量给代码加上括号,方便读者阅读
