Python “If” statement questions

Question

Sorry if my questions are too basic :(
Why does the If statement only evaluates true statement?
Can I make the If statement evaluates false statement?
If possible please show me how.
Thanks

Answer 1

I don't know why you need to write statement like that,
Try to reverse your logic!

Python’s use of indentation is clean, concise, and consistent.

I'm not Pythonic guy, but we have the general Python if-else syntax

if condition :
statement block for True condition

else :
statement block for False condition

HonFu will correcting me if I'm wrong! 👍 // Thanks 😊

You don’t like to be forced to doing things a certain way!

Answer 2

There are two ways
Add a not
Otherwise use pass in if code block and write your code block in else.

if not condition:
do something

if condition:
pass
else :
do something

Answer 3

You can also try this.

if condition == False:
# do something

Answer 4

Imagine a boolean expression like a traffic light: red means 'stop' (False), green means 'go' (True).

So it makes sense that if you give green light, a part of code is executed, otherwise not. If (whatever condition, positive or negative):

Using 'not', you create the opposite statements.

if 3 in [1, 2, 3]:
....

if 3 not in [1, 2, 3]:
...

Everyday logic works the same actually:

'Sir, is it the case that you' re NOT married?'
'Yes, that's TRUE, I'm NOT married.'
'Hm, so... you're married?'
'No, that's FALSE, I just told you I am NOT married!'
