I have had asyncio and websockets work fine several times, but for some reason it sometimes refuses to run and will refuse to ever run again. I have had this happen across multiple devices, with code as simple as just imports:
import asyncio
import json
import websockets
Interestingly, when using Pydroid3 on Android, any code I write with asyncio works fine, but only until I save it to a file. Once it's been saved, it stops working. I can copy all the text and paste it to a new, unsaved file and it again works fine until saved. This awful solution does not work for Windows, unfortunately. I am using Python 3.9.0 for Windows. The stacktrace produced by running the code shown above is as follows:
Traceback (most recent call last):

I've searched a bit for this error, but either it's uncommon or I'm just blind, because I couldn't find anything. Has anyone else had this happen to them?
Your local socket.py file is shadowing Python’s socket module. Rename your file and your imports will work.

I trying to use a python app from github but when trying to launch the app I get the following error which I cannot understand why.

client = discord.Client()
client.run("TheBotTokenzzzInQuotes")

I have my own discord bot that I run, and the client variable for mine doesn't look anything like that if I'm being honest.
If you are not using "Discord.py Rewrite", that could be a possible reason for a failure.
Another possible reason(although very unlikely) is that you do not have aiohttp installed(which is the dependency asyncio needs for Discord.py Rewrite), you can install it by using the following command:
pip install aiohttp
If you would like an example bot to look at, I have listed one below that is directly from the developer of discord.py Rewrite(the version that is currently supported for python).
https://github.com/Rapptz/discord.py/blob/master/examples/basic_bot.py
If you were wondering what the beginning of my code looked like, I have it below this:
import discord
from discord.ext import commands
from discord.utils import get
client = commands.Bot(command_prefix = '>')
I'm taking Python again after a long time.
I'm developing a little software to help me learn a new lengauge (japanese)
I tried to make a class and import it, but it did't work. Just for testing, I created a very simple class and when I tried to import it I got an error.
Here is the code (both files trainer.py and prueba.py are in the same folder):
file trainer.py
class trainer:
def entrenamiento(t,dicc):
print(t)
print(dicc)
file prueba.py
from trainer import entrenamiento
entrenamiento(1,2)
When I run prueba.py I get the following:
C:\Users\nico\AppData\Local\Programs\Python\Python36-32\python.exe C:/Users/nico/PycharmProjects/japanese/prueba.py
Traceback (most recent call last):
File "C:/Users/nico/PycharmProjects/japanese/prueba.py", line 1, in <module>
from trainer import entrenamiento
ImportError: cannot import name 'entrenamiento'
Process finished with exit code 1
I also tried with a different code in prueba.py:
import trainer
trainer.entrenamiento(1,2)
and I got this:
C:\Users\nico\AppData\Local\Programs\Python\Python36-32\python.exe
C:/Users/nico/PycharmProjects/japanese/prueba.py
Traceback (most recent call last):
File "C:/Users/nico/PycharmProjects/japanese/prueba.py", line 3, in <module>
trainer.entrenamiento(1,2)
AttributeError: module 'trainer' has no attribute 'entrenamiento'
Process finished with exit code 1
Finally, just for checking I tried the following
file trainer.py
class trainer:
print('hello world')
file prueba.py
import trainer
and I got no error
C:\Users\nico\AppData\Local\Programs\Python\Python36-32\python.exe
C:/Users/nico/PycharmProjects/japanese/prueba.py
hello world
Process finished with exit code 0
I'm working with Python 3.6.5 and PyCharm 2018.1.4 Community Edition
Is there any mistake in my coding or maybe a configuration issue?
I thank you in advance for your help
Uhm so, you made a little mistake with your import in prueba.py
it should be:
from trainer import trainer
trainer.entrenamiento(1,2)
where the first trainer points to trainer.pyand the second points to the class.
you can now access the function defined inside the class using the syntax class.function eg. trainer.entrenamiento(1,2)
i would recommend to change either the name of trainer.py or the class trainer as it's obviously confusing.
When I import the necessary libraries in the python box sdk into my projects it works perfectly, but when ever another user in my group tries to use the same library it gives me the following error:
Traceback (most recent call last): File
"/home/-------/.../---------.py", line 2, in

This error occurs whether the user uses sudo or not as well as if they import the libraries with this:
from boxsdk import Client, OAuth2
or
import boxsdk
***************** UPDATE
We are all using Python 2.7.12
is_sign_key() uses type annotations.
Compare the output of python --version for you and your colleagues. Downrev python interpreters won't recognize type annotations.
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>
from neo4j import GraphDatabase
File "/usr/lib/python3.2/site-packages/neo4j_embedded-1.6-py3.2.egg/neo4j/__init__.py", line 29, 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 *
