1 | Here‘s an excerpt from the code I‘m using. I‘m looping through the part that adds the email; my problem is rather than changing the "to" field on each loop, it is appending the "to" data. Obviously this causes some issues, since the to 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 list item (also didn‘t work). from email.MIMEMultipart import MIMEMultipart msgRoot = MIMEMultipart(‘related‘) msgRoot[‘To‘] = ‘email@email.com‘ |
You can use the replace_header method.
replace_header(_name, _value)
Replace a header. Replace the first header found in the message that 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@email.com‘
Thank you, that worked perfectly! – Dan Apr 24 ‘11 at 14:26 | |||

Python 3 changed dict syntax. See docs.python.org/3/whatsnew/3.0.html#builtins "Removed. dict.has_key() – use the in operator instead." – gimel Jun 9 ‘16 at 5:31 |
