What is the rule for grouping these items? Below, you suggest:
head encloses neck
neck encloses arms
arms encloses legs
which seems rather strange. But if it is *always* the case that each item
encloses the next item:
def print_nested_list(alist):
spaces = ' '*4
for level, item in enumerate(alist):
if level != 0:
indent = spaces*(level-1) + ' '
print (indent + '|_>'), # note comma
print item
which gives us this:
py> print_nested_list(['head', 'neck', 'arms', 'legs'])
head
|_> neck
|_> arms
|_> legs
as requested.
