python中3 and not 5

这是一个逻辑运算表达式，其中使用了Python中的and和not关键字。and表示逻辑与，not表示逻辑非。在这个表达式中，3表示一个整数，而5也表示一个整数。当使用and连接两个表达式时，只有当两个表达式都为真时，整个表达式才为真。而使用not可以将一个表达式的真假值取反。因此，3 and not 5这个表达式的结果为True。

python if and not

In Python, the if statement is used for conditional execution. allows you to execute a block of code only if a certain condition is true. The not operator can be used to negate a boolean value.
Here's an example of how you can use if and not together:
x = 5

if not x > 10:
print("x is not greater than 10")

In the above code, the condition x > 10 evaluates to False, but since we are using not, it negates the result and makes the condition True. Therefore, the code block inside the if statement will be executed, and it will print "x is not greater than 10" to the console.
You can combine multiple conditions using logical operators like and and or. If you want to check multiple conditions in an if statement, you can use the and operator to combine them. Here's an example:
x = 5
y = 3

if x > 0 and y > 0:
print("Both x and y are positive")

In this case, both conditions x > 0 and y > 0 need to be true for the code block inside the if statement to be executed. If either of them is false, the code block will be skipped.

python and or not优先级

Python中的运算符优先级如下：

括号
指数运算符（**）
正负号（+，-）
乘法、除法、取模运算符（*，/，%）
加法、减法运算符（+，-）
比较运算符（<，>，<=，>=，!=，==）
逻辑运算符not
逻辑运算符and
逻辑运算符or

其中，not的优先级最高，or的优先级最低。
