TypeError: initial_value must be str or None, not bytes

[new2py]

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

The problem is my PyCharm trail period has expired

Use the free community edition of PyCharm.

so I just installed LiClipse and now my script doesn't work.

The error message show now that you use Python 3(as you should),
and have decode content to be a string.
The error message will also show line number,that you have not posted.
I guess change line 22 to this will work.

ids = data[0].decode()

I tried installing line 22, that didn't work, same result
I installed the community version of PyCharm (thanks for the tip) that didn't work, same result

it was working perfectly with the professional version, code is exactly the same

Did you use Python 2 or 3? 

I installed the community version of PyCharm (thanks for the tip) that didn't work, same result

Try change line 26 to:

for response_part in data.decode():

Thanks snippsat,

I found the fix right before i saw your reply
and like you said, change the interpreter from Python 3.6 to 2.7
Now the script is running again!!!
I keep running into this issue,
what are some common compatibility issues between 2.7 and 3.6?
