"IndexError: tuple index out of range"

G'day, I seem to be having trouble running my script in the python console. It looks like this:

def hows_the_parrot():
    print("He's pining for the fjords!") 

hows_the_parrot() 

def lumberjack(name):
    if name.lower () == 'Saihej':
        print("Saihej's a lumberjack and he's OK!")
    else: 
        print("{} sleeps all night and {} works all day!".format(name))

lumberjack("Saihej")

and I receive an error stating this:

He's pining for the fjords! Traceback (most recent call last): File "functions.py" , line 12, in <module> lumberjack("Saihej") File "functions.py", line 10, in lumberjack print("{} sleeps all night and {} works all day!".format(name)) IndexError: tuple index out of range

Can anyone possibly help me with this? I've been receiving all kinds of different errors before, but this one pops up the most, I cannot figure out what I'm formatting properly. it's been bugging me for a few days now >:(, I'm certainly not too good at it yet haha.

Thanks!
