Exactly how do you try using the code? What happens when you do that, and how is that different from what you want to happen? âIt doesnât workâ doesnât explain a problem, so we canât realistically help with it.
I intend to execute the code using Spyder software. The program is designed to log into my company email, search for an email with a specific subject title, and extract three pieces of information: the company name, product of interest, and the date the email was sent. However, the current issue lies in the population of an Excel sheet, as upon inspection, I observed that nothing was written or pasted into it.
And you donât see any error messages? Do you get any output at all?
What happens if you try using print calls to check what parts of the code are running, or what the value of the variables is at various points? For example, right after doing search_criteria = f'(SUBJECT "{subject}")', what do you see if you add print(search_criteria)? Does that look right? How about the resulting messages?
i make change to the code and there is a few error. the error are TypeError: canât concat int to bytes & NameError: name âexitâ is not defined. I apologized in Advances as iâm new to python. here is the new code:

You have shared the errors you are still seeing.
Instead of catching exceptions and just printing the message and quitting like this, you should allow the program to âcrashâ and show a stack trace. That will let you see where the problem occurred, which helps with figuring out what went wrong.
try:/except: is, basically, for when you already understand why the exception might be thrown, and can think of something more useful to do than crash with a stack trace.
NameError: name âexitâ is not defined. happens in your error handler, because exit is not actually a builtin - it comes from the site module, and is only provided by default when you use the REPL, not when running source code files.
i did the changes and now thereâs new error:
TypeError: canât concat int to bytes
During handling of the above exception, another exception occurred:
SystemExit: 1
But which line is raising that error?
Remove exception handling and let it print out the full traceback.
i have check and the first error come from this line
# Fetch message data
print("Fetching message data...")
_, message_data = connection.fetch(message_id, "(RFC822)")
while the other one come from this line
except Exception as e:
handle_error(f"Processing email: {e}")
If you look in the docs youâll find this in the example code:
typ, data = M.search(None, 'ALL')
for num in data[0].split():
typ, data = M.fetch(num, '(RFC822)')
print('Message %s\n%s\n' % (num, data[0][1]))
data[0] (in your code thatâs messages[0]) is a bytestring, so messages[0][0] is returning the first (well, zeroth) byte of the bytestring, which is an int.
Instead, you should be splitting the bytestring to get the message IDs as bytestrings.
For example, if messages[0] is b'12 13' (message IDs 12 and 13), youâre getting 49 (the character code of character '1') instead of b'12' and b'13' (the IDs for messages 12 and 13).
And then connection.fetch is complaining because itâs being given an int instead of a bytestring.

The example code was probably written for Python 2.x, where indexing into a bytes would give a one-element bytes instead of an integer.
