How can I make one list from multiple individual lists that is in one variable with case i=n?

Question

I have data like this:

In[1]: print(z)
Out[2]:
ID          False
CITY        True
ID_STATE    False
STATE       False
ID_COUNTRY  False
COUNTRY     False
AGE         False
Name: 0, dtype: bool
ID          False
CITY        False
ID_STATE    False
STATE       False
ID_COUNTRY  False
COUNTRY     False
AGE         False
Name: 1, dtype: bool
ID          False
CITY        False
ID_STATE    False
STATE       False
ID_COUNTRY  False
COUNTRY     False
AGE         False
Name: 2, dtype: bool
ID          False
CITY        False
ID_STATE    False
STATE       False
ID_COUNTRY  False
COUNTRY     False
AGE         False
Name: 3, dtype: bool

Then I pass this to lists but I don't know if is necessary or it could be converted to just one list at once:

In[3]: print(z.tolist())
out[4]:
[False, True, False, False, False, False, False]
[False, False, False, False, False, False, False]
[False, False, False, False, False, False, False]
[False, False, False, False, False, False, False]
...

Then I would like to get a list from all the bool list data such as:

lst=[False, True, False, False, False, False, False,
False, False, False, False, False, False, False,
False, False, False, False, False, False, False,
False, False, False, False, False, False, False]

I would appreciate if anyone have an idea. Thanks.

Your first output doesn't make sense. Is it supposed to be a lilst of lists? But there's no `[]` for the outer list. — Barmar, Nov 10 '20 at 17:16
It looks like you just want to flatten the list of lists. The fact that they're booleans is irrelevant. — Barmar, Nov 10 '20 at 17:17
No. It supposed to be many list that I wanto to make into one @Barmar . Thank you for answering. — MetalJacket, Nov 10 '20 at 17:24
@Barmar Because I have bool data that I convert to list: `z=rows.tolist()` . — MetalJacket, Nov 10 '20 at 17:27
That should produce a list of lists, not lots of separate lists. — Barmar, Nov 10 '20 at 17:32
If you're using numpy, you can use `rows.flatten().tolist()` — Barmar, Nov 10 '20 at 17:33
I have edited the code @Barmar. I hope have been more specific. Any idea? — MetalJacket, Nov 10 '20 at 17:40
Thanks. I have tried but I did not get it in one list. It just appear as individual lists. @Barmar — MetalJacket, Nov 10 '20 at 17:55
You need to show us what you tried; there's no `ravel` or `flatten` anywhere in your example. — Dour High Arch, Jan 01 '21 at 23:23

You can add them together using +.

res = list()
for i in z:
    res += i
