mail.select("INBOX")
result, numbers = mail.uid('search', None, "ALL")
uids = numbers[0].split()
result, messages = mail.uid('fetch', ','.join(uids), '(BODY[])')
date_list = []
from_list = []

for _, message in messages[::2]:
    msg = email.message_from_string(message)
    if msg.is_multipart():

    for p in msg.get_payload():
        t.append(p.get_payload(decode=True))
        message_text.append(t[0])

    else:message_text.append(msg.get_payload(decode=True))

This line 

result, messages = mail.uid('fetch', ','.join(uids), '(BODY[])')

is raising the exception

TypeError sequence item 0: expected str instance, bytes found

Inspecting the line, 'fetch' and '(BODY[])' are already strings, so they are unlikely to be the problem.

That leaves ','.join(uids). uids is actually a list of bytes instances, so str.join is raising the exception because it expects an iterable of str instances.

To fix the problem, decode numbers[0] to str before manipulating it.

result, numbers = mail.uid('search', None, "ALL")
uids = numbers[0].decode().split()    # <- decode before splitting
result, messages = mail.uid('fetch', ','.join(uids), '(BODY[])')
