why do i need to use elif?

Question

I find that the same result could also be got by only writing two or more if-statements.

Answer 1

well...one difference is that with multiple if statements every condition is checked everytime the program runs through them...with elif statements when a condition is found true, the follow up conditions are not checked...lets say you have x = 3 and y = 4

if x == 3
//something
if y == 4
//something else

in this scenario both if statements are true so both are executed

but if we wrote

if x == 3
//something
elif y == 4
//something else

it is found that the first condition is true and so only that condition's body is executed...the program never checks if y == 4 is true or not because × == 3 is true

if x == 3 was false than and only than the condition y == 4 is checked

Answer 2

Yes, for sure. But with elif it's shorter:

if statement1:
some code
else:
if statement2:
some code

if statement1:
some code
elif statement2:
some code
