Quickstart
What is an Awkward Array?
Converting arrays
NumPy
Python objects
JSON
ROOT via Uproot
Arrow and Parquet
Pandas
Generic buffers
Creating new arrays
ArrayBuilder (easy & general)
Layout (faster)
Unflattening and grouping
Arrays of records
Arrays of strings
Arrays of categories
Lazy arrays
Partitioned arrays
Examining arrays
Data type
Single item detail
Listing fields/keys/columns
Simple slicing
Checking validity
Numerical math
NumPy functions
Awkward broadcasting
Reducing (sum/min/any/all)
Statistics (mean/var/std)
Using argmin/argmax
On GPUs
Filtering data
By number of items
Cuts vs. masks
Slicing lists within arrays
Slices with missing values
Restructuring data
Zip/unzip and project
Adding fields to records
Renaming records
Flattening for plots
Padding/clipping for machine learning
Concatenating and interleaving
Sorting
Combinatorics
Cartesian product and "n choose k"
Best match between collections
