This was flawed, there were two brackets too much:
data=[["Peter",
["Ian",
["Randy",
["Clara"]]]],
"Paul",
["Mary",
["Arthur"]]]

It doesn't show Paul and Mary on the same level. I (think I) solved
the problem with this:
def print_tree(tree, line_columns=[0]):
for i, item in enumerate(tree):
current_line = u""
for j, pos in enumerate(line_columns):
current_line += (pos - j) * " " + "|"
print current_line
if isinstance(item, list):
print current_line[:-1] + "+---> " + item[0]
new_line_columns = line_columns + [line_columns[-1] + 6 +
len(item[0]) // 2]
if i == len(tree) - 1:
del new_line_columns[-2]
print_tree(item[1], new_line_columns)
elif isinstance(item, basestring):
print current_line[:-1] + "+---> " + item
Tschö,
Torsten.
