Converting tuple to list

I am trying to convert this tuple into a list, however when I run this code:

mytuple=('7578',), ('6052',), ('8976',), ('9946',)
List=[]
for i in mytuple:
    Start,Mid,End = map(str, mytuple.split("'"))
    List.append(Mid)
print(List)

I receive this error:

AttributeError: 'tuple' object has no attribute 'split'

The output should be:

[7578, 6052, 8976, 9946]

I would use itertools.chain.from_iterable (which errs on the side of too much verbosity than too little):

from itertools import chain
result = [int(x) for x in chain.from_iterable(mytuple)]
# vs         ... for x, in mytuple]; the comma is easy to miss

Somewhere between the two extremes would be

result = [int(x) for x in chain(*mytuple)]

this is what you are looking for

mytuple = (('7578',), ('6052',), ('8976',), ('9946',))
result = [int(x) for x, in mytuple]
print(result)

If I understood correctly, this is want you want:

mytuple = ('7578',), ('6052',), ('8976',), ('9946',)
result = [e for e, in mytuple]
print(result)

Output

['7578', '6052', '8976', '9946']
