〇、前情提要

在学小甲鱼的使用Python读写Excel文件时，遇到了如下警告：

DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).

DeprecationWarning: Call to deprecated function get_sheet_by_name (Use wb[sheetname]).

DeprecationWarning: Call to deprecated function remove_sheet (Use wb.remove(worksheet) or del wb[sheetname]).

一、报错解释

DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).
不推荐警告：调用已弃用的函数get_sheet_names（请使用wb.sheetnames)
DeprecationWarning: Call to deprecated function get_sheet_by_name (Use wb[sheetname]).
不推荐警告：调用已弃用的函数get_sheet_by_name（请使用wb[sheetname])
DeprecationWarning: Call to deprecated function remove_sheet (Use wb.remove(worksheet) or del wb[sheetname]).
不推荐警告：调用已弃用的函数remove_sheet（请使用Use wb.remove(worksheet) 或者 del wb[sheetname])

二、解决

get_sheet_names改用wb.sheetnames

get_sheet_by_name改用wb[sheetname]

>>> import openpyxl
>>> wb = openpyxl.load_workbook(r"你的excel文件路径")

>>> print(type(wb))
<class 'openpyxl.workbook.workbook.Workbook'>
>>> wb.get_sheet_names()

Warning (from warnings module):
  File "__main__", line 1
DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).
['Sheet']
>>> print(wb.sheetnames)
['Sheet']
>>> ws = wb.get_sheet_by_name('Sheet')

Warning (from warnings module):
  File "__main__", line 1
DeprecationWarning: Call to deprecated function get_sheet_by_name (Use wb[sheetname]).
>>> ws=wb["Sheet"]
>>> ws
<Worksheet "Sheet">
>>> 

remove_sheet改用Use wb.remove(worksheet) 或者 del wb[sheetname]

>>> wb.remove_sheet(wb["FishC Demo"])

Warning (from warnings module):
  File "__main__", line 1
DeprecationWarning: Call to deprecated function remove_sheet (Use wb.remove(worksheet) or del wb[sheetname]).

>>> wb.remove_sheet(wb["FishC Demo"])


>>> print(wb.sheetnames)
['Sheet']
