python xlrd find last row code example

Example: xlrd cell range

import xlrd
import re

def parse_cell(cell):
    r = re.compile("([a-zA-Z]+)([0-9]+)")
    m = r.match(cell)
    col = m.group(1).upper()
    number_row = int(m.group(2)) - 1

    ABC = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]

    number_col = 0
    for char in col:
        number_col += ABC.index(char)

    return (number_row, number_col)

    start_cell_parsed = parse_cell(start_cell)
    end_cell_parsed = parse_cell(end_cell)

    data = sheet.col_values(start_rowx=start_cell_parsed[0], colx=start_cell_parsed[1], end_rowx=end_cell_parsed[0] + 1)
    return data
