Else, If, and Elif.

Question

Why did Python give the option of Putting Else: If, when you could just use the Elif instruction? Is there something extra you could do with it?

E.G

If 1 + 1 = 2:
print("One plus one is two.")
Else:
If 1+1 != 2:
print("One plus one doesn't equal two.")

Instead of--

If 1 + 1 = 2:
print("One plus one is two.")
Elif 1+1 != 2:
print("One plus one doesn't equal two.")

Many Thanks. ^^

Answer 1

if you want to check multiple conditions and none of them are true, else is used printing "input was not correct" or something like that.

Answer 2

x = 2
if x == 1:
doSomething()
elif x == 2:
doSomethingElse()
else:
print(x)

if x == 1:
doSomething()
else:
elif x == 2:
doSomethingElse()
print(x)

Those 2 examples are different. The second case allows you to decide for something to happen regardless of the secondary condition.

Answer 3

else = not all .
elif = an other test .
