possible "if" syntaxes in Python3

So i´d like to know if there´s a way to shorten an "if" that contains more than one command. I know you can do it for single command if´s like:

if x > y:
   print("normal if")

and it becomes:

if x > y: print("shortened if")

But how could it be done in this case for example?

if x > y:
   print("normal if")
   some_number *= 2
