How to combine a group of lists together

[wanghao7915 at gmail.com]

I utilized .get_text() + .split() functions and obtain this:
spe=
['$278.86as', 'of', 'Dec', '20,', '2019,', '06:47', 'PST', '-', 'Details']
['4.7', 'inches']
['750', 'x', '1334']
['64', 'GB']
['2', 'GB']
['Apple', 'A11', 'Bionic,', 'Hexa-Core,', '(2x', 'Monsoon', '+', '4x', 'Mistral)']
['5.22', 'ounces']
['No']
['No']
['12', 'MP']
['7', 'MP']
['1821', 'mah']
['No']
['Yes,', 'on', 'the', 'front']
['None']
['iOS', '(Last', 'OS', 'info:', 'IOS', '11)']
['September', '2017']

They have a shared name 'spe', but no concrete names for each list.
If I use spe[0], I can only get all the first element of each list.

How can I mix all of these elements into a single list like:
['$278.86as', 'of', 'Dec', '20,', '2019,', '06:47', 'PST', '-', 'Details','4.7', 'inches'......]

Thanks!
