9. usys module

See: https://docs.micropython.org/en/latest/library/sys.html
Some attributes are listed below. Use help(usys) to get the full list.
These are values, not functions, so they are used without brackets, e.g. usys.platform.
usys.version_info
The Python language version, as a tuple of ints.
e.g. (3, 4, 0)
from microbit import *
import usys

display.scroll(str(usys.version_info), delay=80)  # (3, 4, 0)
usys.version
The Python language version, as a string.
e.g. 3.4.0
from microbit import *
import usys

display.scroll(usys.version, delay=80)  # 3.4.0
usys.platform
The platform that MicroPython is running on.
e.g. microbit
from microbit import *
import usys

display.scroll(usys.platform, delay=80)  # microbit
usys.implementation
Information about the current MicroPython implementation, with these attributes:
name - string e.g. micropython, from usys.implementation.name
version - tuple (major, minor, micro), e.g. (1, 18, 0), from usys.implementation.version
from microbit import *
import usys

display.scroll(usys.implementation.name, delay=80)          # micropython
display.scroll(str(usys.implementation.version), delay=80)  # (1, 18, 0)
usys.maxsize
The maximum integer value that can be stored in a native integer, which is 2,147,483,647 for a 32-bit system.
from microbit import *
import usys

display.scroll(usys.maxsize, delay=80)  # 2147483647
if usys.maxsize > 2147483648:
    display.scroll("64-bit", delay=80)
else:
    display.scroll("32-bit", delay=80)
usys.modules
A dictionary of loaded modules, not including builtin modules.
e.g. {‘log’: <module ‘log’>, ‘neopixel’: <module ‘neopixel’>}
The log module shows in the list once it has been imported.
from microbit import *
import usys

import log

display.scroll(str(list(usys.modules)), delay=80)  # ['log']
usys.path
A list of directories to search for imported modules.
e.g. [‘’, ‘.frozen’]
from microbit import *
import usys

display.scroll(str(usys.path), delay=80)  # ['', '.frozen']
usys.byteorder
The byte order of the system (“little” or “big”).
e.g. little
from microbit import *
import usys

display.scroll(usys.byteorder, delay=80)  # little
usys.argv
A list of arguments the current program was started with. e.g. []
from microbit import *
import usys

display.scroll(str(usys.argv), delay=80)  # []
The code below scrolls all the values in one program.
from microbit import *
import usys

# print(help(usys))
# print('version_info:', usys.version_info)
display.scroll('version_info: ' + str(usys.version_info), delay=80)
# print('version:', usys.version)
display.scroll('version: ' + str(usys.version), delay=80)
# print('platform:', usys.platform)
display.scroll('platform: ' + str(usys.platform), delay=80)
# print('implementation name:', usys.implementation.name)
display.scroll('implementation name: ' + str(usys.implementation.name), delay=80)
# print('implementation version:', usys.implementation.version)
display.scroll('implementation version: ' + str(usys.implementation.version), delay=80)
# print('maxsize:', usys.maxsize)
display.scroll('maxsize: ' + str(usys.maxsize), delay=80)
if usys.maxsize > 2147483648:
    # print('64-bit')
    display.scroll('64-bit', delay=80)
else:
    # print('32-bit')
    display.scroll('32-bit', delay=80)
# print('path:', usys.path)
display.scroll('path: ' + str(usys.path), delay=80)
# print('modules:', usys.modules)
display.scroll('modules: ' + str(usys.modules), delay=80)
# print('byteorder:', usys.byteorder)
display.scroll('byteorder: ' + str(usys.byteorder), delay=80)
# print('argv:', usys.argv)
display.scroll('argv: ' + str(usys.argv), delay=80)
