list1 = [[[1,2,3],[4,5,6],[7,8,9],[10,11,12]],[[13,14,15],[16,17,18],[19,20,21],[22,23,24]]]
for i in range(0,2):
print(list1[:][i][1])
output =
[4, 5, 6]
[16, 17, 18]
how do I get the above code to work such that:
desired output =
2 14
5 17
What is the correct indexing notation for the list? I'm having particular trouble with the list[:] format as it seems to be ignored by the above code. Thx
Something like?
>>> print(*map(' '.join, zip(*[map(str, list(zip(*x[:2]))[1]) for x in list1])), sep='\n')
2 14
5 17
>>>
Or:
>>> print(*map(' '.join, zip(*[(str(x[0][1]), str(x[1][1])) for x in list1])), sep='\n')
2 14
5 17
>>>
To make it work on your code you would have to do:
for i in range(0,2):
print(list1[0][i][1], list1[1][i][1])
Out:
2 14
5 17
The reason it your code didn't work is because it is getting the sublist from i, not the sublist's sublist.
