python list to newline separated value
Solution 1
"\n".join(item[0] for item in my_list)
However, what's this got to do with JSON...?
Solution 2
Your code is doing what you want it to, but I imagine you're inspecting the results in the python REPL or ipython, and expecting to see new lines instead of '\n'.
In [1]: items = [["abc"], ["pqr"],["xyz"]]
In [2]: s = "\n".join(item[0] for item in items)
In [3]: s
Out[3]: 'abc\npqr\nxyz'
In [4]: print s
abc
pqr
xyz
Solution 3
I am not exactly sure what you want, but you may try:
nested_list = [ ["abc"], ["pqr"], ["xyz"] ]
data = "\n".join( (item[0] for item in nested_list) )
This will convert your list of lists into a string separated by newline characters.
Solution 4
Er I'm not sure what exactly you want, but if you need to print that you could do
for l in data:
print l[0]
or if you want to make it a flat list, you could do something like
map(lambda x: x[0], a)
or if you even just want a single string with newlines, you could do something like
"\n".join(map(lambda x: x[0], a))
Dunno if that helped at all, but wish you luck
