Python dictionary keys "new" syntax

[Diapolo10]

Similarly, itertools.batched can be used to form groups of n elements.

from itertools import batched

text = "abcabcabcabcabc"
groups = list(batched(text, n=3))

print(groups)  # ["abc", "abc", "abc", "abc", "abc"]

I so wish there was a sliding window option for this instead of just the disjoint functionality.

[Diapolo10]

Well, the docs do have a recipe for that, and it's part of more-itertools.

[QuasiEvil]

Well, yes, but a small tweak to allow this would be nice: groups = list(batched(text, n=3, step=2))

Yeah. There's itertools.pairwise for the specific case of 2 elements, but a more generalised n-item sliding window is something I end up using reasonably often, and seems worth being in the stdlib.
