How To Reference the Current Region of a Given Cell Using xlwings?

Method

What is the current region of a given cell? 

The shaded area in the image indicates the current region of cell `C3`. The current region of a cell refers to the rectangular area that expands from the cell in all four directions until a rectangular area surrounded by empty spaces is reached, i.e., where there are empty rows or columns in the four directions (within the region, not across the entire row/column).

 
Sample Code

#Referencing the Current Cell Range of a Specified Cell

import xlwings as xw    #Import the xlwings package

app=xw.App()
bk=app.books.open('current.xlsx')    #Get the active workbook
sht=bk.sheets.active    #Get the active worksheet

#xlwings
sht.range('C3').current_region.select()

#xlwings API
#sht.api.Range('C3').CurrentRegion.Select()

#bk.close()
#app.kill()
