A list comprehension:
tup_after = [v for t in tup_Before for v in t]
or use itertools.chain.from_iterable()
:
from itertools import chain
tup_after = list(chain.from_iterable(tup_Before))
Demo:
>>> tup_Before = [(69592, 69582), (69582, 69518), (69518, 69532), (69532, 69525)]
>>> [v for t in tup_Before for v in t]
[69592, 69582, 69582, 69518, 69518, 69532, 69532, 69525]
>>> from itertools import chain
>>> list(chain.from_iterable(tup_Before))
[69592, 69582, 69582, 69518, 69518, 69532, 69532, 69525]
