使用xlwt'get_sheet'方法访问工作表 [英] Accessing worksheets using xlwt 'get_sheet' method
问题描述
我想访问电子表格的工作表.我已经使用xlutils.copy()将主要工作簿复制到了另一个工作簿.但是不知道使用xlwt模块访问工作表的正确方法. 我的示例代码:
I would like to access worksheets of a spreadsheet. I've copied the main workbook to another workbook using xlutils.copy(). But don't know the right way to access worksheets using xlwt module. My sample code:
import xlrd
import xlwt
from xlutils.copy import copy
wb1 = xlrd.open_workbook('workbook1.xls', formatting_info=True)
wb2 = copy(master_wb)
worksheet_name = 'XYZ' (worksheet_name is a iterative parameter)
worksheet = wb2.get_sheet(worksheet_name)
有人可以告诉我使用xlwt模块访问工作簿中现有工作表的正确命令行是什么吗?我知道我们可以使用xlwt模块使用'add_sheet'方法在现有工作簿中添加工作表.
Could someone please tell me what's the right command line to access the existing worksheets in a workbook using xlwt module? I know we can use 'add_sheet' method to add a worksheet in the existing workbook using xlwt module.
任何帮助,谢谢.
推荐答案
xlwt.Workbook
类奇怪地缺少sheets()
方法,因此使用该方法的其他答案将不起作用-仅xlrd.book
(用于阅读) XLS文件)具有sheets()
方法.因为所有的类属性都是私有的,所以您必须执行以下操作:
The sheets()
method is curiously absent from the xlwt.Workbook
class, so the other answer using that method will not work - only xlrd.book
(for reading XLS files) has a sheets()
method. Because all the class attributes are private, you have to do something like this:
def get_sheet_by_name(book, name):
"""Get a sheet by name from xlwt.Workbook, a strangely missing method.
Returns None if no sheet with the given name is present.
"""
# Note, we have to use exceptions for flow control because the
# xlwt API is broken and gives us no other choice.
try:
for idx in itertools.count():
sheet = book.get_sheet(idx)
if sheet.name == name:
return sheet
except IndexError:
return None
如果不需要它为不存在的工作表返回None,则只需删除try/except块.如果要按名称重复访问多个工作表,将它们放入字典中会更有效,例如:
If you don't need it to return None for a non-existent sheet then just remove the try/except block. If you want to access multiple sheets by name repeatedly it would be more efficient to put them in a dictionary, like this:
sheets = {}
try:
for idx in itertools.count():
sheet = book.get_sheet(idx)
sheets[sheet.name] = sheet
except IndexError:
pass
