List comprehension if-else in one line

Question

I'm shortening a code and trying to compress an if/else statement but I don't how to.
This is what I have
If opcn1 == 1:
var1 = X
Elif opcn1 == 2:
Var1 = Y
Elif opcn1 == 3:
Var1 = Z
Elif opcn1 == n...
etc...

Answer 1

You can try this :))
var1 = X if opcn1 == 1 else Y if opcn1 == 2 else Z if opcn1 == 3 else ....
Example :
x = 1
y = 'one' if x == 1 else 'two' if x == 2 else 'idk'
print(y) # one

Answer 2

You can use a tuple:
Var1 = (None, X, Y, Z)[opcn1]
