How to turn a list into nested dict in Python

Question

Need to turn x:

X = [[\'A\', \'B\', \'C\'], [\'A\', \'B\', \'D\']]

Into Y:

Y = {\'A\': {\'B\': {\'C\',\'D\'}}}

Answer 1

There is a logical inconsistency in your problem statement. If you really want ['xyz/123/file.txt', 'abc/456/otherfile.txt']

to be changed to {'xyz': {'123': 'file.txt}, 'abc': {'456': 'otherfile.txt'}}

Then you have to answer how a path 'abc.txt' with no leading folder would be inserted into this data structure. Would the top-level dictionary key be the empty string ''?
