sharing your code

Work out what’s wrong

There’s your problem: the recursive invocation of your function is using the
old function signature that required only one argument. The new version of
your function requires two arguments.
The fix is easy: provide the correct number of arguments when calling the
new version of your function. So, this snippet of code from your function:

if isinstance(each_item, list):
print_lol(each_item)

needs to be rewritten to specify the correct number of arguments:

if isinstance(each_item, list):
print_lol(each_item, level)

Not so fast. Surely the nested
list needs to be printed after a specific
number of tab-stops? At the moment, your
code sets “level” to 0 but never changes the
value, so “level” never has any impact on your
displayed output...

Right. Your use of “level” needs one final tweak.
The whole point of having level as an argument is to allow you to
control the nested output. Each time you process a nested list, you need
to increase the value of level by 1. Your code snippet needs to look
like this:

if isinstance(each_item, list):
print_lol(each_item, level+1)

Simply increment the value of level by 1 each

It’s time to perform that update. time you recursively invoke your function.
