Using relative paths in Microsoft Outlook COM with win32com

Question

I created a function to send email of my output using win32com.client in a Ppython script.

app = win32com.client.Dispatch('Outlook.Application')
mail = app.CreateItem(0)
mail.Subject = 'Output file'
mail.Body = 'Output file'
mail.To = 'foo@bar.com'
attachment = 'E:\\python\\outputfile.xlsx'
mail.Attachments.Add(attachment)
mail.Send()

It works good but I have a small issue. It finds the attachment only if I give the entire path. For example,

attachment='outputfile.xlsx'

or

attachment="\\outputfile.xlsx"

causes the error

4096, 'Microsoft Outlook', 'File name or directory name is not valid.'

I want to make the code portable so that it could find the file from its own directory.

最简单的方法是import os并使用os.path.abspath('outputfile.xlsx') 。
