Ak.zip ⭐ Tested: By passing a dictionary to ak.zip , you can create named fields. The primary purpose of ak.zip is to take several arrays and "zip" them together so that each element of the resulting array is a record (like a row in a table) containing values from each input array. ak.zip : It is frequently used when reading from or writing to ROOT files (standard in physics) to ensure that attributes with the same "raggedness" (like jet or muon properties) are grouped correctly for storage. How to concatenate and interleave arrays : By passing a dictionary to ak : It is specifically designed to handle "ragged" or jagged data, where nested lists may have different lengths across different entries. Key Parameters According to the Awkward Array documentation : How to concatenate and interleave arrays : It : Controls how deeply the function should interleave the lists. Setting depth_limit=1 creates a record structure at the outermost level without attempting to broadcast deeper nested lists. # Example: Creating a record array with fields "x" and "y" import awkward as ak array = ak.zip({"x": [1, 2, 3], "y": [1.1, 2.2, 3.3]}) # Result: Use code with caution. Copied to clipboard : If you pass a list or tuple of arrays instead of a dictionary, it creates an array of unnamed tuples.
