python针对Excel表格的操作

pip install openpyxl

import openpyxl# 1. 打开一个excel文档, 
class 'openpyxl.workbook.workbook.Workbook'实例化出来的对象wb = openpyxl.load_workbook('Book.xlsx')
print(wb, type(wb))# 获取当前工作薄里所有的工作表，和正在使用的表;print(wb.sheetnames)
print(wb.active)

# 2.选择要操作的工作表，返回工作表对象sheet=wb['Sheet1']
#获取工作表的名称print(sheet.title)

# 3. 返回指定行指定列的单元格信息print(sheet.cell(row=1, column=2).value)
cell = sheet['B1']print(cell)print(cell.row, cell.column, cell.value)

# 4. 获取工作表中行和列的最大值print(sheet.max_column)print(sheet.max_row)
sheet.title = '学生信息'print(sheet.title)

# 5. 访问单元格的所有信息print(sheet.rows)  
# 返回一个生成器， 包含文件的每一行内容， 可以通过便利访问.
# 循环遍历每一行for row in sheet.rows:    
# 循环遍历每一个单元格for cell in row:        
# 获取单元格的内容
   print(cell.value, end=',')
 print()

#6.保存修改信息wb.save(filename='Boom.xlsx')
