Hi, lets say you have: [[8,0,5]]

but you want: [8,0,5]

how might we go about doing that?

Thanks

If you have many lists (a list of lists) then to reduce that by one level of depth, concatenate.

See itertools.chain (that’s concatenate, just a different name)

not python, but to show the behaviour:

>>> concat [[[8,0,5]]]
[[8,0,5]]
>>> concat [[8,0,5]]
[8,0,5]
>>> concat [[8],[0,5]]
[8,0,5]
>>> concat []
[]
