            fp.write(part.get_payload(decode=True))
            fp.close()

moirod did you get this figured out? I just ran into the same error and it's because I'm using Python 3, which has a different syntax for the print statement. Just wrap everything after the print statement in parenthesis like print(whatever + "you want to print")

Hai i would like to request u i wanna some code here
How to read and display at sametime gmail attachements in a python window....?
and im using windows OS using python version 2.7.14

I have tried executing this code but it shows the following error:

Traceback (most recent call last):
File "config.py", line 25, in
mail = email.message_from_string(email_body)
File "C:\Users\sappa\AppData\Local\Programs\Python\Python37-32\lib\email_init_.py", line 38, in message_from_string
return Parser(*args, **kws).parsestr(s)
File "C:\Users\sappa\AppData\Local\Programs\Python\Python37-32\lib\email\parser.py", line 68, in parsestr
return self.parse(StringIO(text), headersonly=headersonly)
TypeError: initial_value must be str or None, not bytes

SOLVED IT 💯

                                                            mail = email.message_from_string(email_body)

The above line in the code must be replaced with the following line and it works perfectly

                                                            mail = email.message_from_bytes(email_body)

in short: "email.message_from_string" must be replaced with "email.message_from_bytes". Because the data is present in bytes not in the string format.

Thanks for that @RahulSapparapu !
In addition to that, I had to make the following minor changes to make it python3 compatible

1. Use input in place of raw_input
2. Use additional single quote at

('"[Gmail]/All Mail"')

4. Use parentheses at

print("["+mail["From"]+"] :" + subject)

Finally, added the following to filename as my attachments were of the same name and were getting overwritten:

datestring = mail['date']
datestring2 = utils.parsedate_to_datetime(datestring).strftime("%Y_%m_%d")
filename = datestring2 + '_' + part.get_filename()

Thank you @styrmis for sharing this!
