I have a list in Python 2.7 that looks like this.
[[u'ABC'], [u'DEF'], [u'GHI']]
Now, I want to convert it so it should be like this.
['ABC', 'DEF', 'GHI']
How can I do this?

1There are two components to this, have you researched either of them? – jonrsharpe May 06 '20 at 10:21

Not even sure what the second component is, this is really just flattening a list. It’s questionable why you think the leading `u` should be removed at all. – deceze May 06 '20 at 10:23

`[val[0] for val in [[u'ABC'], [u'DEF'], [u'GHI']]]` will do, but please move to Python 3! – Bruno Vermeulen May 06 '20 at 10:31

If your list is named arr you can do arr = [i[0].encode('ascii') for i in arr]. Note this assumes that each element is a list of only (and at least) one item and that you aren't concerned about there being non-ASCII characters in the string

Welcome to Python. This is just flattening a list
flattened_list = [val[0] for val in [[u'ABC'], [u'DEF'], [u'GHI']]]
print(flattened_list)
By the way please move to Python 3!
