What is the difference between using 'if' repeatedly and using 'elif' in Python?

Well to make it a simple way to explain
If "this is a question"
Give an answer
Else
Say I don't know
Simple if else.
elif is a little bit different
If "This is a question"
"Give answer 1"
elif
"Give answer 2"
elif
"Give answer 3"
else
"Say I don't know
I know its not the code but as you can see there is a vital difference, you want to give multiple IF states with elif. while if its IF you give a IF and ELSE statement.

Multiple 'if' statements get checked one after another with no regard to the former's results.
'Elif' acts as 'else if', so is checked only in the 'else' case - that is only then, if the first 'if' is False. If the first 'if' is True, all 'elif' statements are skipped and not checked anymore.

By using if repeatedly you will ask all if conditions, no matter if any other before that was true.
With elif you evaluate the first if, and if it is false THEN evaluate the second, if both of them were false THEN the third and so on, if any of them was true you stop evaluating the next conditions

Now I got it! Thanks.. 😋

Here's the difference:
(if - if - else)
x = input()
if x = 1:
print("x is equal to 1")
if x != 2:
print("x is not equal to 2")
else:
print("poop")
say that we input 1
the output would be:
x is equal to 1
x is not equal to 2
however if we use elif instead of another if:
(if - elif - else)
x = input()
if x = 1:
print("x is equal to 1")
elif x != 2:
print("x is not equal to 2")
else:
print("poop")
say that we input 1
the output would only be:
x is equal to 1
just supplementing what kuba said.
YAY!

Actually I want to say ....
if - requires a condition, can be repeatedly used using different conditions.
elif - also requires a condition, can be repeatedly used using different conditions. I found no difference between using is statement repeatedly and using elif statement. Like we can use 'if' statement also in case of 'elif'...so what is the necessity of using 'elif'?
