Two sets of curly brackets not working in lumberjack()

Hi, when I use two sets of braces (as shown in the video) for the string in the else: part of the lumberjack function, I get an error as shown below. If I remove a set of braces, the function runs ok. What is causing this please?

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

hows_the_parrot()

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

lumberjack("Kenneth")

The error message:

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

If you put two sets of braces in the string, it means you need to pass to arguments in the format function, otherwise, python doesn't know where to put your name. 

print("{} sleeps all night and {} works all day!".format(name, name))

Also, you have code like 

if name.lower() == 'Kenneth':

In your case, it should be:

if name.lower() == 'kenneth':

name.lower() will never be equal to the string that begins with the uppercase letter because you transform your name string into all lowercase letters.
