9. usys module

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

Some functions are listed below. Use print(help(usys)) to get the full list.

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 tuple, (name=’micropython’, version=(1, 18, 0)), 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, 18, 0) Also returned by: usys.implementation.version

usys.maxsize(): Returns the maximum integer value that can be represented on the platform, which is 2,147,483,647 for a 32-bit system.

usys.modules(): Returns a dictionary of loaded modules, not including builtin modules.

e.g. {‘log’: <module ‘log’>, ‘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. e.g. []

The code below uses the REPL to print the output.

from microbit import *
import usys

# print(help(usys))
print('version_info:', usys.version_info)
print('version:', usys.version)
print('platform:', usys.platform)
print('implementation name:', usys.implementation.name)
print('implementation version:', usys.implementation.version)
print('maxsize:', usys.maxsize)
if usys.maxsize > 2147483648:
    print('64-bit')
else:
    print('32-bit')
print('path:', usys.path)
print('modules:', usys.modules)
print('byteorder:', usys.byteorder)
print('argv:', usys.argv)
