This module is deprecated since version 2.3: The email package should be used in preference to the rfc822 module. This module is present only to maintain backward compatibility, and has been removed in Python 3.
For more information visit this : Deprecated Link
But here is another module which is plone.rfc822
This package provides primitives for turning content objects described by zope.schema fields into RFC (2)822 style messages. It utilizes the Python standard library’s email module.
For installation: pip install plone.rfc822

I try to execute the file on my iTerm terminal and it's working fine. Can you tell me why it is n ot working in vscode?
I'm using Python 3.7.9
I have installed the package using pip3 install azure-eventhub (I have also tried with just pip) but the modules are still interpreting as missing whereas there are not.
Using pip show azure-eventhub WARNING: Package(s) not found: azure-eventhub but it is there I can see the package in /usr/local/lib/python3.10/site-packages
The code uses a Reddit wrapper called praw
Here is part of the code:
import praw
from praw.models import MoreComments
username = 'myusername'
userAgent = 'MyAppName/0.1 by ' + username
clientId = 'myclientID'
clientSecret = 'myclientSecret'
threadId = input('Enter your thread id: ');
reddit = praw.Reddit(user_agent=userAgent, client_id=clientId, client_secret=clientSecret)
submission = reddit.submission(id=threadId)
subredditName = submission.subreddit
subredditName = str(subredditName)
act = input('type in here what you want to see: ')
comment_queue = submission.comments[:] # Seed with top-level
submission.comments.replace_more(limit=None)
def dialogues():
for comment in submission.comments.list():
if comment.body.count('"')>7 or comment.body.count('\n')>3:
print(comment.body + '\n \n \n')
def maxLen():
res = 'abc'
for comment in submission.comments.list():

Since I am new to Python and don't really get programming in general, I am surprised to see that the every bit of code in the commandline works but I get an error in IDLE on the first line saying ModuleNotFoundError: No module named 'praw'
you have to install praw using the command
pip install praw which install latest version of praw in the environment
What must be happening is that your cmd and idle are using different python interpreters i.e., you have two different modules which can execute python code. It can either be different versions of python or it can be the same version but, installed in different locations in your machine.
Let's call the two interpreters as PyA and PyB for now. If you have pip install praw in PyA, only PyA will be able to import and execute functions from that library. PyB still has no idea what praw means.
What you can do is install the library for PyB and everything will be good to go.
How do I load a python module, that is not built in. I'm trying to create a plugin system for a small project im working on. How do I load those "plugins" into python? And, instaed of calling "import module", use a string to reference the module.
Have a look at importlib
Option 1: Import an arbitrary file in an arbiatrary path
Assume there's a module at /path/to/my/custom/module.py containing the following contents:
# /path/to/my/custom/module.py
test_var = 'hello'
def test_func():
print(test_var)
We can import this module using the following code:
import importlib.machinery
myfile = '/path/to/my/custom/module.py'
sfl = importlib.machinery.SourceFileLoader('mymod', myfile)
mymod = sfl.load_module()
The module is imported and assigned to the variable mymod. We can then access the module's contents as:
mymod.test_var
# prints 'hello' to the console
mymod.test_func()
# also prints 'hello' to the console
Option 2: Import a module from a package
Use importlib.import_module
For example, if you want to import settings from a settings.py file in your application root folder, you could use
_settings = importlib.import_module('settings')
The popular task queue package Celery uses this a lot, rather than giving you code examples here, please check out their git repository
I have been using "ipython --script" to automatically save a .py file for each ipython notebook so I can use it to import classes into other notebooks. But this recenty stopped working, and I get the following error message:
`--script` is deprecated. You can trigger nbconvert via pre- or post-save hooks:
ContentsManager.pre_save_hook
FileContentsManager.post_save_hook
A post-save hook has been registered that calls:
ipython nbconvert --to script [notebook]
which behaves similarly to `--script`.
As I understand this I need to set up a post-save hook, but I do not understand how to do this. Can someone explain?
[UPDATED per comment by #mobius dumpling]
Find your config files:
Jupyter / ipython >= 4.0
jupyter --config-dir
ipython <4.0
ipython locate profile default
If you need a new config:
Jupyter / ipython >= 4.0
jupyter notebook --generate-config
ipython <4.0
ipython profile create
Within this directory, there will be a file called [jupyter | ipython]_notebook_config.py, put the following code from ipython's GitHub issues page in that file:
import os
from subprocess import check_call
c = get_config()
def post_save(model, os_path, contents_manager):
"""post-save hook for converting notebooks to .py scripts"""
if model['type'] != 'notebook':
return # only do this for notebooks
d, fname = os.path.split(os_path)
check_call(['ipython', 'nbconvert', '--to', 'script', fname], cwd=d)
c.FileContentsManager.post_save_hook = post_save
For Jupyter, replace ipython with jupyter in check_call.
Note that there's a corresponding 'pre-save' hook, and also that you can call any subprocess or run any arbitrary code there...if you want to do any thing fancy like checking some condition first, notifying API consumers, or adding a git commit for the saved script.
Cheers,
-t.
Here is another approach that doesn't invoke a new thread (with check_call). Add the following to jupyter_notebook_config.py as in Tristan's answer:
import io
import os
from notebook.utils import to_api_path
_script_exporter = None
def script_post_save(model, os_path, contents_manager, **kwargs):
"""convert notebooks to Python script after save with nbconvert
replaces `ipython notebook --script`
"""
from nbconvert.exporters.script import ScriptExporter
if model['type'] != 'notebook':
return
global _script_exporter
if _script_exporter is None:
_script_exporter = ScriptExporter(parent=contents_manager)
log = contents_manager.log
base, ext = os.path.splitext(os_path)
py_fname = base + '.py'
script, resources = _script_exporter.from_filename(os_path)
script_fname = base + resources.get('output_extension', '.txt')
log.info("Saving script /%s", to_api_path(script_fname, contents_manager.root_dir))
with io.open(script_fname, 'w', encoding='utf-8') as f:
f.write(script)
c.FileContentsManager.post_save_hook = script_post_save
Disclaimer: I'm pretty sure I got this from SO somwhere, but can't find it now. Putting it here so it's easier to find in future (:
I just encountered a problem where I didn't have rights to restart my Jupyter instance, and so the post-save hook I wanted couldn't be applied.
So, I extracted the key parts and could run this with python manual_post_save_hook.py:
from io import open
from re import sub
from os.path import splitext
from nbconvert.exporters.script import ScriptExporter
for nb_path in ['notebook1.ipynb', 'notebook2.ipynb']:
base, ext = splitext(nb_path)
script, resources = ScriptExporter().from_filename(nb_path)
# mine happen to all be in Python so I needn't bother with the full flexibility
script_fname = base + '.py'
with open(script_fname, 'w', encoding='utf-8') as f:
# remove 'In [ ]' commented lines peppered about
f.write(sub(r'[\n]{2}# In\[[0-9 ]+\]:\s+[\n]{2}', '\n', script))
You can add your own bells and whistles as you would with the standard post save hook, and the config is the correct way to proceed; sharing this for others who might end up in a similar pinch where they can't get the config edits to go into action.
so I installed neo4j on ArchLinux (AUR Link) and want to test it using python 3.2.
I am using python 3.2, Eclipse with Pydev.
I tried following code from the neo4j website, allthough I think it was still 2.7 python code and I tried to convert it to Python 3.2 code.
Here's the code:
import os
libpath = '/usr/share/java/neo4j'
os.environ['CLASSPATH'] = ';'.join( [ os.path.abspath(p) for p in
os.listdir(libpath)])
from neo4j import GraphDatabase
# Create a database
db = GraphDatabase('/home/USERNAME/.db/neo4j/HelloWorld')
# All write operations happen in a transaction
with db.transaction:
firstNode = db.node(name='Hello')
secondNode = db.node(name='world!')
# Create a relationship with type 'knows'
relationship = firstNode.knows(secondNode, name='graphy')
# Read operations can happen anywhere
message = ' '.join([firstNode['name'], relationship['name'], secondNode['name']])
print(message)
# Delete the data
with db.transaction:
firstNode.knows.single.delete()
firstNode.delete()
secondNode.delete()
# Always shut down your database when your application exits
db.shutdown()
But I get following error message:
Traceback (most recent call last):
File "/home/USERNAME/PATH/TO/src/neo4j-HelloWorld.py", line 12, in <module>

I just can't figure out what's wrong!
I tried to set the CLASSPATH as described here, but it doesn't change anything.
I would really appreciate any help!
Did you run the code through 2to3?
If not, I suggest you do.
I think the problem is that the relative import syntax changed in 3.x, see PEP328 for details.
e.g. the offending import in core.py should probably say from ._backend import *
