python如何与excel结合

>>> import openpyxl
>>> wb = openpyxl.load_workbook(r'D:PycharmProjects
equests250.xlsx')
>>> type(wb)
<class 'openpyxl.workbook.workbook.Workbook'>

>>> wb.get_sheet_names()
['Sheet']
>>> wb.sheetnames
['Sheet']
>>> ws = wb.get_sheet_by_name('Sheet') # 工作表对象

>>> rnx = wb.create_sheet(index = 0,title = 'sheet1')
>>> wb.get_sheet_names()
['sheet1', 'Sheet']
# 注意删除工作表时，要删除工作表的对象 ws = wb.get_sheet_by_name('工作表')
>>> wb.remove_sheet(wb.get_sheet_by_name('sheet1'))
>>> wb.sheetnames
['Sheet']

>>> c = ws['A2']
>>> c.row 
2
>>> c.column
'A'
>>> c.coordinate
'A2'
>>> d = c.offset(2,0)
>>> d.value
'这个杀手不太冷'

>>> openpyxl.cell.cell.get_column_letter(27)
'AA'
>>> openpyxl.cell.cell.column_index_from_string('AA')
27

>>> for each_movies in ws['A2':'B10']: # each_movies是一个元祖
 for each_cell in each_movies:
 print(each_cell.value,end = ' ')
 print('
')
