如何使用 Python 将 excel 转换为 pdf 并定向为水平

Question

我有一个excel sheet，我想使用python 将其转换为pdf。我可以使用下面的代码来做到这一点：

import win32com.client
from pywintypes import com_error

WB_PATH = 'test.xls'
PATH_TO_PDF = 'test.pdf'

excel = win32com.client.Dispatch("Excel.Application")

excel.Visible = False

try:
    wb = excel.Workbooks.Open(WB_PATH)
    ws_index_list = [1]
    wb.WorkSheets(ws_index_list).Select()
    wb.ActiveSheet.ExportAsFixedFormat(0, PATH_TO_PDF)
except com_error as e:
    print('failed.')
else:
    print('Succeeded.')
finally:
    wb.Close()
    excel.Quit()

这工作正常，但问题是它在垂直布局中将 excel 转换为 pdf。我在excel中有很多列，因为有些列进入了第二页，看起来不太好。下面是截图：

以上是excel表格截图。

上图是 pdf 的第一页，其中包含直到滚动停止时间列的数据，其余包含在第二页中：

如何将方向更改为水平，以便所有列都适合第一页。请帮忙。谢谢

更新代码：

import win32com.client
from pywintypes import com_error


WB_PATH = 'test.xls'

PATH_TO_PDF = 'test.pdf'

excel = win32com.client.Dispatch("Excel.Application")
excel.Visible = False

try:
    wb = excel.Workbooks.Open(WB_PATH)
    wb.Worksheets("sheet")

    ws_index_list = [1]
    ws_source = wb.WorkSheets(ws_index_list)
    ws_source.PageSetup.Orientation = 2
    ws_source.Select()

    wb.ActiveSheet.ExportAsFixedFormat(0, PATH_TO_PDF)
except com_error as e:
    print('failed.')
else:
    print('Succeeded.')
finally:
    wb.Close()
    excel.Quit()

但上面的代码给出了错误：

AttributeError: <unknown>.PageSetup

import win32com.client
from pywintypes import com_error

WB_PATH = 'test.xls'
PATH_TO_PDF = 'test.pdf'

excel = win32com.client.Dispatch("Excel.Application")

excel.Visible = False

try:
    wb = excel.Workbooks.Open(WB_PATH)
    ws_source.PageSetup.Orientation = 2 # orient the format before you print to pdf
    ws_index_list = [1]
    wb.WorkSheets(ws_index_list).Select()
    wb.ActiveSheet.ExportAsFixedFormat(0, PATH_TO_PDF)
except com_error as e:
    print('failed.')
else:
    print('Succeeded.')
finally:
    wb.Close()
    excel.Quit()
# I'm not a very experienced programmer but this should help. I would orient
# the file first before printing it to pdf
