Hi Jamshaid Ali!

If is the beginning of a conditional statement. Think of it in English like "If there are eggs in my fridge -> cook them". You can only have one If statement in the chain of If/Elif/Else. Therefore there is Elif (Short for Else If), which acts just like If but says "None of the If/Elseif above me passed, do I pass? Else is a "Nothing passed, so I want to do this instead."

if eggs in fridge:
    eggs.eat()
elif toast in pantry:
    toast.eat()
elif coffee in coffee_pot:
    coffee.drink()
else: #Nothing passed, default to this one.
    orderDelivery()

I hope that helps. Here is a good article to read:

Happy coding!
