```python
import xlrd
workbook = xlrd.open_workbook("sample.xlsx")
sheet = workbook.sheet_by_index(0)
print("Number of rows: ", sheet.nrows)
print("Number of columns: ", sheet.ncols)
Replace sample.xlsx with the path to an actual Excel file on your computer. Run the script using the following command:
