Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make. In the whole scheme of things, micropython is quite small: % size bin/micropython text data bss dec hex filename 393495 1624 2208 397327 6100f bin/micropython % and runs much as expected: % bin/micropython MicroPython v1.5.2 on 2016-01-13; linux version Use Ctrl-D to exit, Ctrl-E for paste mode >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> % python2.7 Python 2.7.10 (default, Oct 17 2015, 17:55:29) [GCC 4.8.5] on netbsd7 Type "help", "copyright", "credits" or "license" for more information. >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> ^D % This (reachover) version runs all the tests which the gmake version does. % make t cd bin && make t cd /home/agc/local/micropython/bin/../dist/unix/../tests && env MICROPY_MICROPYTHON=/home/agc/local/micropython/bin/micropython ./run-tests pass basics/0prelim.py pass basics/andor.py pass basics/array1.py pass basics/array_add.py pass basics/array_construct.py pass basics/array_construct2.py ... pass unix/ffi_callback.py pass unix/ffi_float.py pass unix/ffi_float2.py 474 tests performed (15812 individual testcases) 474 tests passed 5 tests skipped: cmd_showbc cmd_verbose machine1 machine_mem extra_coverage % The sources are available from github: https://github.com/micropython/micropython micropython release at: https://github.com/micropython/micropython/releases Sources for 1.5.2 taken from: https://github.com/micropython/micropython/archive/v1.5.2.tar.gz Alistair Crooks agc@@netbsd.org Wed Jan 13 17:15:30 PST 2016 @ text @@
