Standard Library

Codon implements much of Python's standard library natively. Some built-in modules and some methods of certain modules are not yet available natively in Codon; these can still be called through Python, however:

import sys              # uses Codon's native 'sys' module
from python import sys  # uses Python's 'sys' module

Built-in modules¶

The following built-in modules are supported either in full or in part natively in Codon:

Module	Notes
`copy`
`gzip`
`random`	Matches CPython's `random` outputs for same seed.
`threading`	Locks work with Codon's parallel programming features.
`bisect`
`datetime`	`timedelta` are represented in microseconds. Time zones not supported.
`heapq`
`operator`
`re`	Uses Google's RE2 library internally.
`time`
`bz2`
`os`
`cmath`
`functools`
`itertools`
`statistics`
`typing`	Contents are available by default in Codon.
`getopt`
`math`
`pickle`	Codon uses its own pickle format, so generally not compatible with CPython pickling.
`string`
`collections`
`sys`

Additional modules¶

Alongside the standard modules above, Codon provides several additional modules that support various Codon-specific features.

openmp: Contains OpenMP API, which can be used when writing multithreaded programs. See multithreading for more information.
gpu: Contains GPU API (e.g. CUDA intrinsics), which can be used when writing GPU code. See GPU for more information.
python: Contains internal machinery for interfacing with CPython. Most users will not need to interact with this module directly.
experimental: Contains experimental features that are available for use, but might not be stable nor complete.
