the `if not` syntax in python is used to check if a condition is false. it is the opposite of `if` where you check if a condition is true.

here's the general syntax of using `if not` in python:



in this syntax:
`condition` is an expression that is evaluated to either true or false.
if the condition is evaluated to false, the code block inside the `if not` statement will be executed.

now, let's see a code example to demonstrate the usage of `if not`:



in this example, the condition `x 20` is false because `x` is 10 which is not greater than 20. therefore, the code block inside the `if not` statement will be executed and it will print "x is not greater than 20".

you can also use `if not` with boolean variables or expressions. here's another example:



in this example, since `is_raining` is false, the code block inside the `if not` statement will be executed and it will print "it's not raining today".

that's how you can use the `if not` syntax in python to check if a condition is false.
