I actually have the answer except for a glitch where on list element is an int.

My code

for item in data:
    out = '[{0}]'.format("][".join(item))
    print(out)

which prints out

[glossary]
[glossary][title]
[glossary][GlossDiv]
[glossary][GlossDiv][title]
[glossary][GlossDiv][GlossList]
....

However, in my source I have two lines like this

 ['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'GlossDef', 'GlossSeeAlso', 0],
 ['glossary', 'GlossDiv', 'GlossList', 'GlossEntry', 'GlossDef', 'GlossSeeAlso', 1],

when it hits these lines I get 

TypeError: sequence item 6: expected str instance, int found

Do I need to do an explicit check for these 2 cases or is there a simpler way?

Cheers

Sayth
