I receive similar emails from multiple senders and use regular expressions m and n below to pull out needed strings. That part is working fine.
Regular expression o however is what has me confused. The text file I am reading is a combination of 9 email messages saved to one text file and opened in Python as a string. Original Sender (regex o) occurs at the beginning of each new message in the file (9 times)
I want to write the same Original Sender after each CUSIP and NAME found until a different Original Sender is matched.
I am using xlwt3 and wincom32.
Sample from the text file with combined emails which is very standard:
--- Original Sender: TOM MADEUPNAME, SOME BANK, N. ---
----- Original Message -----
From: TOM MADEUPNAME (SOME BANK, N.)

Your question isn’t completely clear since you didn’t show an output sample, but here’s an educated guess:
Rather than writing the Original Sender when encountered, you need to save it and write the current value for each cusip and name.
