So, to start, I was making a discord bot (using discord.py) and making a help command, but it shows an error when I run the python file
I have no idea what was going on about this... (\n didn't cause the problem)
code (new one):
#client.command(aliases=["commands","cmds"], description="Get command list")
async def help(ctx):
embed = discord.Embed(title="Commands",description="List of the bot's commands",color=0xFF0000)
for commands in client.commands:
embed.add_field(name=commands,value=commands.description)
await ctx.send(embed)
and full error message:
Traceback (most recent call last):

lines = doc.expandtabs().split('\n')

would be nice if someone could help me
also, this is my first post (and I'm new here) so I don't know much about Stack Overflow
(PS: I have client.help_command = None in my code, thanks Kermit)
The description argument takes a string, not a list. So, it should look like this:
#client.command(aliases=["commands","cmds"], description="Get command list")
Also, make sure you have client.help_command = None somewhere in your code, so that the default help command provided by discord.py can be overridden.
The immediate issue is that the description kwarg of the command decorator is being given a list when it expects a string, which can be found out from the Command documentation.
However more importantly, as it appears you're trying to create your own help command, that is not the recommended way to do so since you forgo the advantages of the existing HelpCommand framework that handles argument parsing for you. If you need help with using it, check out this guide which goes through subclassing and adding it to your bot.
Sidenote: for future questions, please provide the full error message so it's easier for other users to debug.

I'm trying to customize the !help command of my Discord bot using commands.HelpCommand, but I'm note sure to understand how it works.
My actual (minimal) code is the following:
bot.remove_command("help")
#bot.command()
async def help(ctx, *, command=None):
hc = commands.HelpCommand()
await hc.command_callback(ctx, command=command)
But I encounter this exception:
Traceback (most recent call last):
File "[...]/bot.py", line 229, in help
await hc.command_callback(ctx, command=command)
File "[...]/python3.8/site-packages/discord/ext/commands/help.py", line 782, in command_callback
mapping = self.get_bot_mapping()
File "[...]/python3.8/site-packages/discord/ext/commands/help.py", line 331, in get_bot_mapping
bot = self.context.bot
AttributeError: 'NoneType' object has no attribute 'bot'
I understand that HelpCommand.command_callback needs HelpCommand.context to be set... but the doc states that
This (context) is generally set after the help command assigned, command_callback(), has been called.
That sounds like a bug for me, but I'm not sure to fully understand how to implement HelpCommand...
I tried to move it into a cog, to pass context=ctx to HelpCommand during initialization and other things, without success.
Any idea?
Thanks in advance!
Okay, if it can help anyone, I just noticed the help_command parameter of commands.Bot...
You just have to pass it your HelpCommand instance!
No need to do any tricky workaround, I was indeed misunderstanding things.
So I have tried to write a small config file for my script, which should specify an IP address, a port and a URL which should be created via interpolation using the former two variables. My config.ini looks like this:
[Client]
recv_url : http://%(recv_host):%(recv_port)/rpm_list/api/
recv_host = 172.28.128.5
recv_port = 5000
column_list = Name,Version,Build_Date,Host,Release,Architecture,Install_Date,Group,Size,License,Signature,Source_RPM,Build_Host,Relocations,Packager,Vendor,URL,Summary
In my script I parse this config file as follows:
config = SafeConfigParser()
config.read('config.ini')
column_list = config.get('Client', 'column_list').split(',')
URL = config.get('Client', 'recv_url')
If I run my script, this results in:
Traceback (most recent call last):
File "server_side_agent.py", line 56, in <module>
URL = config.get('Client', 'recv_url')
File "/usr/lib64/python2.7/ConfigParser.py", line 623, in get
return self._interpolate(section, option, value, d)

"bad interpolation variable reference %r" % rest)
ConfigParser.InterpolationSyntaxError: bad interpolation variable reference '%(recv_host):%(recv_port)/rpm_list/api/'
I have tried debugging, which resulted in giving me one more line of error code:
...
ConfigParser.InterpolationSyntaxError: bad interpolation variable reference '%(recv_host):%(recv_port)/rpm_list/api/'
Exception AttributeError: "'NoneType' object has no attribute 'path'" in <function _remove at 0x7fc4d32c46e0> ignored
Here I am stuck. I don't know where this _remove function is supposed to be... I tried searching for what the message is supposed to tell me, but quite frankly I have no idea. So...
Is there something wrong with my code?
What does '< function _remove at ... >' mean?
There was indeed a mistake in my config.ini file. I did not regard the s at the end of %(...)s as a necessary syntax element. I suppose it refers to "string" but I couldn't really confirm this.
My .ini file for starting the Python Pyramid server had a similar problem.
And to use the variable from the .env file, I needed to add the following: %%(VARIEBLE_FOR_EXAMPLE)s
But I got other problems, and I solved them with this: How can I use a system environment variable inside a pyramid ini file?
I am using python/Zope for development.
Currently i'm formatting a date object to the format "%m-%d-%Y" in one of files. The code is shown below
if resultSet :
for eachResult in resultSet :
DateTime(eachResult['txntime']).strftime("%m-%d-%Y")
This is triggering the following error:
File "Script (Python)", line 37, in CronJobFindUnmatchedTransfer_v2_1
File "/opt/zope-2.7/lib/python/DateTime/DateTime.py", line 750, in __init
s,d = _calcSD(t)
File "/opt/zope-2.7/lib/python/DateTime/DateTime.py", line 331, in _calcSD
d = dd / 86400.0
I didn't have any idea on this. Somebody please help me out..
You are passing a value into the DateTime() constructor that is not supported by that class. What you are passing in is unclear though.
In Zope, when it reports a traceback for an exception (writes it to the log, passes it to the error view), it includes any local variable with the name __traceback_info__ when printing each stack. This is used to include debug information in the logged exception.
Use this to track what values you are passing to DateTime():
if resultSet:
for eachResult in resultSet:
__traceback_info__ = (eachResult['txntime'],)
DateTime(eachResult['txntime']).strftime("%m-%d-%Y")
Run Zope in foreground mode (bin/instance fg or zopectl fg, depending on what version you have and how it was installed), and watch for the traceback being dumped to stderr. It'll have an extra line with the value of eachResult['txntime'] included in the traceback.
I have an issue, where a function returns a number. When I then try to assemble a URL that includes that number I am met with failure.
Specifically the error I get is
TypeError: cannot concatenate 'str' and 'NoneType' objects
Not sure where to go from here.
Here is the relevant piece of code:
# Get the raw ID number of the current configuration
configurationID = generate_configurationID()
# Update config name at in Cloud
updateConfigLog = open(logBase+'change_config_name_log.xml', 'w')
# Redirect stdout to file
sys.stdout = updateConfigLog
rest.rest(('put', baseURL+'configurations/'+configurationID+'?name=this_is_a_test_', user, token))
sys.stdout = sys.__stdout__
It works perfectly if I manually type the following into rest.rest()
rest.rest(('put', http://myurl.com/configurations/123456?name=this_is_a_test_, myusername, mypassword))
I have tried str(configurationID) and it spits back a number, but I no longer get the rest of the URL...
Ideas? Help?
OK... In an attempt to show my baseURL and my configurationID here is what I did.
print 'baseURL: '+baseURL
print 'configurationID: '+configurationID
and here is what I got back
it-tone:trunk USER$ ./skynet.py fresh
baseURL: https://myurl.com/
369596
Traceback (most recent call last):
File "./skynet.py", line 173, in <module>
main()
File "./skynet.py", line 30, in main
fresh()
File "./skynet.py", line 162, in fresh
updateConfiguration()
File "./skynet.py", line 78, in updateConfiguration
print 'configurationID: '+configurationID
TypeError: cannot concatenate 'str' and 'NoneType' objects
it-tone:trunk USER$
What is interesting to me is that the 369596 is the config ID, but like before it seems to clobber everything called up around it.
As kindall pointed out below, my generate_configurationID was not returning the value, but rather it was printing it.
# from generate_configurationID
def generate_configurationID():
dom = parse(logBase+'provision_template_log.xml')
name = dom.getElementsByTagName('id')
p = name[0].firstChild.nodeValue
print p
return p
Your configurationID is None. This likely means that generate_configurationID() is not returning a value. There is no way in Python for a variable name to "lose" its value. The only way, in the code you posted, for configurationID to be None is for generate_configurationID() to return None which is what will happen if you don't explicitly return any value.
"But it prints the configurationID right on the screen!" you may object. Sure, but that's probably in generate_configurationID() where you are printing it to make sure it's right but forgetting to return it.
You may prove me wrong by posting generate_configurationID() in its entirety, and I will admit that your program is magic.
Hey guys, I am a little lost on how to get the auth token. Here is the code I am using on the return from authorizing my app:
client = gdata.service.GDataService()
gdata.alt.appengine.run_on_appengine(client)
sessionToken = gdata.auth.extract_auth_sub_token_from_url(self.request.uri)
client.UpgradeToSessionToken(sessionToken)
logging.info(client.GetAuthSubToken())
what gets logged is "None" so that does seem right :-(
if I use this:
temp = client.upgrade_to_session_token(sessionToken)
logging.info(dump(temp))
I get this:
{'scopes': ['http://www.google.com/calendar/feeds/'], 'auth_header': 'AuthSub token=CNKe7drpFRDzp8uVARjD-s-wAg'}
so I can see that I am getting a AuthSub Token and I guess I could just parse that and grab the token but that doesn't seem like the way things should work.
If I try to use AuthSubTokenInfo I get this:
Traceback (most recent call last):
File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/ext/webapp/__init__.py", line 507, in __call__
handler.get(*groups)
File "controllers/indexController.py", line 47, in get
logging.info(client.AuthSubTokenInfo())
File "/Users/matthusby/Dropbox/appengine/projects/FBCal/gdata/service.py", line 938, in AuthSubTokenInfo
token = self.token_store.find_token(scopes[0])
TypeError: 'NoneType' object is unsubscriptable
so it looks like my token_store is not getting filled in correctly, is that something I should be doing?
Also I am using gdata 2.0.9
Thanks
Matt
To answer my own question:
When you get the Token just call:
client.token_store.add_token(sessionToken)
and App Engine will store it in a new entity type for you. Then when making calls to the calendar service just dont set the authsubtoken as it will take care of that for you also.
