TypeError: initial_value must be str or None, not bytes

Hello, I am new to Python, got my first script (that I found online) working. The problem is my PyCharm trail period has expired, so I just installed LiClipse and now my script doesn't work. The script extracts email addresses from your Inbox that's inside a folder:

#!/usr/bin/python

import imaplib
import sys
import email
import re

FOLDER = sys.argv[0]
FOLDER = "EMPLOYMENT3"
LOGIN = "emailaddresshere"
PASSWORD = "passwordhere"
IMAP_HOST = "imap.mail.yahoo.com"  # Change this according to your provider

email_list = []
email_unique = []

mail = imaplib.IMAP4_SSL(IMAP_HOST)
mail.login(LOGIN, PASSWORD)
mail.select(FOLDER)

result, data = mail.search(None, 'ALL')
ids = data[0]
id_list = ids.split()
for i in id_list:
	typ, data = mail.fetch(i,'(RFC822)')
	for response_part in data:
		if isinstance(response_part, tuple):
			msg = email.message_from_string(response_part[1])
			sender = msg['from'].split()[-1]
			address = re.sub(r'[<>]','',sender)
# Ignore any occurences of own email address and add to list
	if not re.search(r'' + re.escape(LOGIN),address) and not address in email_list:
		email_list.append(address)
		print(address)

This is the error message I get ever since I switched from PyCharm to LiClipse:



TypeError: initial_value must be str or None, not bytes
