Python利用openpyxl库遍历Sheet的实例

方法一，利用 sheet.iter_rows() 获取 Sheet1 表中的所有行，然后遍历

import openpyxl 
wb = openpyxl.load_workbook('example.xlsx') 
sheet = wb.get_sheet_by_name('Sheet1') 
for row in sheet.iter_rows(): 
 for cell in row: 
  print(cell.coordinate, cell.value) 
print('--- END OF ROW ---')

sheet = wb.get_sheet_by_name('Sheet1') 
for rowOfCellObjects in sheet['A1':'C3']: 
 for cellObj in rowOfCellObjects: 
  print(cellObj.coordinate, cellObj.value) 
print('--- END OF ROW ---')

方法二，利用 sheet.max_row sheet.max_colum 获取 Sheet1 表中最大行和列的值，然后遍历
