逻辑运算符

and or not 同时存在，先算括号，然后算not，然后算and，最后算or
print(3>4 or 4<3 and 1==1) # False
print(False or False and True)

x or y 如果x==0，那么就是y，否则是x
print(0 or 1 or 3 or 0 or 5) #1

x and y 如果x==0，那么就是x，否则是y
print(1 and 2)#2
print(0 and 4) #0

print(0 or 4 and 3 or 7 or 6) #3

print(2 > 5 and 3) # False
print(False and 3)相当于print(0 and 3)为0
print(2 < 1 and 4 > 6 or 3 and 4 >5 or 6)
print( F or F or 6)
print(0 or 0 or 6 ) #6
