triple quotes cause index errors

My code is this:

underhill = input('''{}, do you understand Python while loops?
(Enter yes/no)  '''.format(name))

while underhill.lower() != 'yes':
    underhill = input('''Ok, {}, Python while loops repeat as long as a certain Boolean condition is met.
{}, now do you understand Python while loops?
(Enter yes/no)  '''.format(name))


print("That's great, {}. I'm pleased that you understand while loops now. That was getting repeatitive.".format(name))```

Hiya Angelus Miculek

This is actually happening because there are two { } within that sentence it's showing in the error but only one variable to format it with provided. You'll simply need to add in name twice like so...

while underhill.lower() != 'yes':
    underhill = input('''Ok, {}, Python while loops repeat as long as a certain Boolean condition is met.
{}, now do you understand Python while loops?
(Enter yes/no)  '''.format(name, name))

In your provided code above I assumed you still had this up top

name = input("What's your name? ")

Things seemed to be working fine after that addition 👍

treehouse:~/workspace$ python looping.py
What's your name? a
a, do you understand Python while loops?
(Enter yes/no) no
Traceback (most recent call last):
File "/home/treehouse/workspace/looping.py", line 18, in <module>
underhill = input('''Ok, {}, Python while loops repeat as long as a certain Boolean condition is m et.
IndexError: Replacement index 1 out of range for positional args tuple

No clue why this error happens when I say no. Is it the triple quotes?
