I have updated your code to make it work. The errors were due to wrong quotes. I have added comments to the lines which are edited.

import win32com.client as win32
outlook=win32.Dispatch('outlook.application')
mail=outlook.CreateItem(0)
email_t4='[email protected];[email protected];[email protected]' # Add quotes to value
mail.To=email_t4 # Remove quotes for teating as variable
mail.CC='[email protected]'
mail.BCC='[email protected]'

mail.Subject='ABC'
mail.Body='XYZ'

mail.HTMLBody='<h1>Report</h1>' # Quoted this as it was not valid syntax

attachment4=r'C:\temp\python\test.txt'

mail.Attachments.Add(attachment4)

mail.Send()
