Visit adjacent pairs.

Python: Use itertools.pairwise to process neighboring items without indexing.

Python snippet.py
from itertools import pairwise
print(list(pairwise([10, 20, 35])))

Expected output EXAMPLE

[(10, 20), (20, 35)]

Details

Save as snippet.py and run python3 snippet.py. Uses the Python standard library. Use itertools.pairwise to process neighboring items without indexing.

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
