Hi Dotan!  Welcome to python!

Here is some code that will do what you need.  It uses the re module,
which are regular expressions.

# You need to import the module:
import re

# Then you need to read in the file that contains your list.
email_list = open("brokenemails.txt","r")

# We need to generate your regular expression.  The grabs anything in
# the file that is between < and >, but it includes the <>

# Then filter each line of the file through the regex, discarding the
# <> from above, and puts each address into a list.
addresses = [re_mail.search(line).group(1) for line in

# Now we print them out, comma and newline separated
print ",\n".join(addresses)

Let me know if you need more detail!

Your pal,
