How to get Python system size terminal mode

1. A method for introducing a first module sys;

>>> import sys
>>>
>>> sys.byteorder
'little' >>>

2. The second method, using the module array, with the integer signed integer 4 bytes:

    |      Type code   C Type             Minimum size in bytes
    |      'b'         signed integer     1
    |      'B'         unsigned integer   1
    |      'u'         Unicode character  2 (see note)
    |      'h'         signed integer     2
    |      'H'         unsigned integer   2
    |      'i'         signed integer     2
    |      'I'         unsigned integer   2
    |      'l'         signed integer     4
    |      'L'         unsigned integer   4
    |      'q'         signed integer     8 (see note)
    |      'Q'         unsigned integer   8 (see note)
    |      'f'         floating point     4
    |      'd'         floating point     8

 

>>> import array
>>> a = array.array('l',[1])
>>>
>>> bytes(a)
b'\x01\x00\x00\x00'
>>>
>>> a = array.array('l',[255])
>>> bytes(a)
b'\xff\x00\x00\x00'
>>>
>>>
>>> a = array.array('l',[65535])
>>>
>>> bytes(a)
b'\xff\xff\x00\x00'
>>>
>>>

 

In the low address holding low, this machine uses little-endian mode.
