Test script:

{{{
#!/usr/bin/env python3
import ctypes
import termios
import fcntl
from ctypes import Structure, c_ushort

class WinSize(Structure):
     _fields_ = [(""ws_row"", c_ushort),
                 (""ws_col"", c_ushort),
                 (""ws_xpixel"", c_ushort),
                 (""ws_ypixel"", c_ushort)
                 ]

sz = WinSize()
fcntl.ioctl(0, termios.TIOCGWINSZ, sz)
print(sz.ws_row, sz.ws_col, sz.ws_xpixel, sz.ws_ypixel)
}}}


Running the above script with Python 3.10.9 with MC I get:
>>> 44 206 0 0

Exiting MC to the undelying shell I get:
>>> 44 206 1651 752
