Modify the From, to fields in the original Python file

here ' s an excerpt from the code I ' m using. I ' m looping through the part of that adds the email; My problem is rather than changing the ' to ' field on each loop and it is appending the ' to ' data. Obviously this causes some issues, since-field ends up getting longer and longer. I tried Msgroot.del_param (' to ') to no avail. I even tried setting the msgroot[' to ') to refer to the first index of a list so I could simply change the value of that Li ST Item (also didn ' t work). From email. Mimemultipart Import mimemultipartmsgroot = Mimemultipart (' related ') msgroot[' to '] = ' [email protected] '

you can use the  replace_header  method.

replace_header (_name, _value)

Replace a header. Replace the first header found in the message this matches _name, retaining header order and field name case. If no matching header was found, a keyerror is raised.

New in version 2.2.2.

For example,

If Msgroot.has_key (' to '): Msgroot.replace_header ("to", someadress) else:msgroot[' to '] = ' [email protected] '

thank you, that worked perfectly!  – dan apr ' at 14:26
