Use the xlrd module, xlrd reads Excel, and xlrd operates excel in xls/xlxs format
step:
1. Import xlrd models
2. Open Excel to complete instantiation
3. Get the corresponding table by subscript (you can get it by table name)
4. Obtain table data by column, row or coordinate
file format:
py file:
import xlrd
