BIFs have their very own namespace called they need to write and worry about, which

and a good night’s sleep.

Now that you know a bit about the range() BIF, amend your function to use range() to
indent any nested lists a specific number of tab-stops.
Hint: To display a TAB character on screen using the print() BIF yet avoid taking a new-line
(which is print()’s default behavior), use this Python code: print("\t", end='').

def print_lol(the_list, ):

number of tab-stops.
