python如何与excel结合

>>> import openpyxl

>>> wb = openpyxl.load_workbook(r'D:\PycharmProjects\requests\250.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('\n')
