The BioMini SDK does not have official support for Python.  

Some Example of Python that show tom load the DLL and use the functions in python , please check

from ctypes import *

mydll = windll.LoadLibrary("./UFScanner.dll")
result = mydll.UFS_Init()
print(f'result : {result}')

saveFile = 'testOutputFile.bmp'
scannerNum = c_int()
scannerHandle = c_void_p()
saveFileName = saveFile.encode('utf-8')
result = mydll.UFS_GetScannerNumber(byref(scannerNum))

if scannerNum.value > 0:
result = mydll.UFS_GetScannerHandle(0, byref(scannerHandle))
print(f'scannerHandle : {scannerHandle}')

result = mydll.UFS_CaptureSingleImage(scannerHandle)
print(f'result : {result}')

if result == 0:
result = mydll.UFS_SaveCaptureImageBufferToBMP(scannerHandle, create_string_buffer(saveFileName))

result = mydll.UFS_Uninit()
print(f'result : {result}')
