See: https://docs.micropython.org/en/latest/library/sys.html

Some functions are listed below. Use print(help(usys)) to get the full list. path – [‘’, ‘.frozen’] argv – []

implementation – (name=’micropython’, version=(1, 18, 0)) byteorder – little exit – <function> modules – {} print_exception – <function>

usys.version_info()

Returns the Python language version, as a tuple of ints.

e.g. (3, 4, 0)

usys.version()

Returns the Python language version, as a string.

e.g. 3.4.0

usys.platform()

Returns the platform that MicroPython is running on.

e.g. microbit

usys.implementation()

Returns a a tuple with information about the current MicroPython implementation with following attributes:

name - string e.g. micropython. Also returned directly by: usys.implementation.name

version - tuple (major, minor, micro), e.g. (1, 15, 0) Also returned by: usys.implementation.version

usys.maxsize()

Returns the maximum integer value that can be saved on the current platform. It returns the number of bytes of heap RAM that are allocated.

usys.modules()

Returns a dictionary of loaded modules, not including builtin modules.

e.g. {‘BitBotXL’: <module ‘BitBotXL’>, ‘neopixel’: <module ‘neopixel’>}

usys.path()

Returns a list of directories to search for imported modules.

e.g. [‘’, ‘.frozen’]

usys.byteorder()

Returns the byte order of the system (“little” or “big”).

e.g. little

usys.argv()

Returns a list of arguments the current program was started with.
