Er I'm not sure what exactly you want, but if you need to print that you could do
呃，我不确定你到底想要什么，但如果你需要打印，你可以做
for l in data:
print l[0]
or if you want to make it a flat list, you could do something like
或者如果你想让它成为一个平面列表，你可以做一些类似的事情
map(lambda x: x[0], a)
or if you even just want a single string with newlines, you could do something like
或者如果你甚至只想要一个带换行符的字符串，你可以做类似的事情
"\n".join(map(lambda x: x[0], a))
Dunno if that helped at all, but wish you luck
不知道这是否有帮助，但祝你好运

"\n".join(item[0] for item in my_list)
However, what's this got to do with JSON...?
但是，这与 JSON 有什么关系...？

I am not exactly sure what you want, but you may try:
我不确定你想要什么，但你可以尝试：
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.
这会将您的列表列表转换为由换行符分隔的字符串。

I think you want this, though it's hard to know based on your description:
我想你想要这个，尽管根据你的描述很难知道：
>>> l = [["abc"],["pqr"],["xyz"]]
>>> "".join(map(lambda a:a[0] + "\n",l))
'abc\npqr\nxyz\n'

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'.
您的代码正在执行您想要的操作，但我想您正在检查 python REPL 或 ipython 中的结果，并希望看到新行而不是 '\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
