How to convert a list made up of one tuple into a two item list?

Question

I have a function that returns a one item list, like so:
list = [('array_1','array_2')]

I want to change this so that the list is instead a two item one, without the parentheses or single quotes:
list = [array_1,array_2]

What would be the best way to go about doing this?

You could just typecast like this.
list = list([('array_1','array_2')][0])

You can try this:
lst_tuple = [('array_1', 'array_2')]
lst = []
for i in lst_tuple[0]:
    lst.append(i)

By iteratating over the list that contains the tuple and appending each item to a new list, you can get this result:
['array_1', 'array_2']

Use chain.from_iterable
from itertools import chain

list(chain.from_iterable([('array_1','array_2')]))

['array_1', 'array_2']

Try this
 lists = [('array_1','array_2')]
print([y for x in lists for y in x])

output
['array_1', 'array_2']
