i can sequence single character indexes like

Output:>>> a='abcdefghijklmnopqrstuvwxyz'
>>> [a[x] for x in range(-6,6)]
['u', 'v', 'w', 'x', 'y', 'z', 'a', 'b', 'c', 'd', 'e', 'f']
>>> a[-6:6]
''
>>>

but a slice doesn't work anywhere near that way. so, i have to do

Output:>>> ''.join(a[x] for x in range(-6,6))
'uvwxyzabcdef'
>>>

is there a more direct way using a slice to get this?

Did you try a[-6:]+a[:6] ?

In [1]: a='abcdefghijklmnopqrstuvwxyz'

In [2]: a[-6:6:-1]
Out[2]: 'utsrqponmlkjih'

wavic: i want to go in the forward direction, not backwards.
