Creates a multipart-mixed MIME message with the 1st part containing plain-text, and the 2nd part containing a GIF image.

 Chilkat Python Module Downloads for Windows, Linux, and MAC OS X

import sys
import chilkat

mime = chilkat.CkMime()

success = mime.UnlockComponent("Anything for 30-day trial.")
if (success == False):
    print mime.lastErrorText()
    sys.exit()

#  Initialize a multipart-mixed MIME message:
mime.NewMultipartMixed()

#  Each sub-part will be prepared, then added to the
#  top-level multipart/mixed MIME object, and then written
#  to a file.

#  First the plain-text sub-part
#  Add a few header fields:
textPart = chilkat.CkMime()
textPart.AddHeaderField("Description","this is a test")
textPart.AddHeaderField("MyId","123")
textPart.SetBodyFromPlainText("This is the plain-text body")

#  Now for a GIF image:
imagePart = chilkat.CkMime()
success = imagePart.SetBodyFromFile("starfish.gif")
if (success == False):
    print imagePart.lastErrorText()
    sys.exit()

#  Append each sub-part to the top-level MIME object:
mime.AppendPart(textPart)
mime.AppendPart(imagePart)

#  Write the full multipart-mixed MIME to a file.
success = mime.SaveMime("out.mim")
if (success == False):
    print mime.lastErrorText()
    sys.exit()

print mime.getMime()

#  The MIME should look something like this:
#  (See more comments following this sample output...)
