I ask for help because I literally have no idea what I have to do for this. I'm bangin my head for 2 days and I have to admit that I just dont get it...
I need a script to set the view in the sequencer to
bpy.ops.sequencer.view_all() (or similarly: bpy.ops.sequencer.view_selected())
To do that I need to override the context and tell the script it has to run that command in the sequencer area, if not it will give a:
Python: Traceback (most recent call last):
File "\Text", line 4, in <module>
File "F:\MEDIA\GAMES\Steam\steamapps\common\Blender\3.4\scripts\modules\bpy\ops.py", line 113, in __call__
ret = _op_call(self.idname_py(), None, kw)
RuntimeError: Operator bpy.ops.sequencer.view_all.poll() failed, context is incorrect
..and of course just setting:
bpy.context.area.ui_type = 'SEQUENCE_EDITOR'
..does nothing
But again I have absolutely no idea what to do so, any help would be highly apreciated..
Here is the correct context override:
import bpy
# go through all areas until sequence editor is found
for area in bpy.context.screen.areas:
if area.type == "SEQUENCE_EDITOR":
override = bpy.context.copy()
# change context to the sequencer
override["area"] = area
override["region"] = area.regions[-1]
# run the command with the correct context
with bpy.context.temp_override(**override):
bpy.ops.sequencer.view_all()
break

dpg.add_color_picker(label="Pick", default_value=(0, 0, 0))
This code does not. A runtime error occurs on line 2. I do not understand how a with statement with no as affects the contents of the with. I've seen another similar post, but I can't understand how the explanation answers my question.
Here is the stacktrace for the error:
The above exception was the direct cause of the following exception:
Traceback (most recent call last):

On the Python side: Context managers run completely arbitrary code on enter and exit. Python doesn't force that code to do things "behind your back", but neither does it present them from doing so; so the implementation of the specific context manager at hand needs to be inspected to know why it's modifying behavior.
From a DearPyGui perspective: The C++ library that dpg backends into maintains a "container stack". Entering a container as a context manager ensures that it's on the top of your stack. When you create a new DearPyGui object that needs to be attached to a container, it refers to that stack, and attaches itself to the thing that is currently on top.
Using the translation provided by PEP-343, you can see that
with dpg.window(label="Window"):
...
is equivalent to
mgr = dpg.window(label="Window")
exit = type(mgr.__exit__)
value = type(mgr).__enter__(mgr)
exc = True
try:
try:
...
except:
exc = False
if not exit(mgr, *sys.exc_info()):
raise
finally:
if exc:
exit(mgr, None, None, None)
You can compare the above to the fuller translation in PEP-343 to see the single line I omitted that results from the use of as.
In your examples, dpg.window(label="Window").__enter__ is called in the first example, but not in the second.
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):

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 recently installed python-WikEdDiff package to my system. I understand it is a python extension of the original JavaScript WikEdDiff tool. I tried to use it but I couldn't find any documentation for it. I am stuck at using WikEdDiff.diff(). I wish to use the other functions of this class, such as getFragments() and others, but on checking, it shows the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.4/dist-packages/WikEdDiff/diff.py", line 1123, in detectBlocks
self.getSameBlocks()
File "/usr/local/lib/python3.4/dist-packages/WikEdDiff/diff.py", line 1211, in getSameBlocks
while j is not None and self.oldText.tokens[j].link is None:
IndexError: list index out of range
On checking, I found out that the tokens[] structure in the object remains empty whereas it should have been initialized.
Is there an initialize function that I need to call apart from the default constructor? Or is it something to do with the `WikEdDiffConfig' config structure I passed to the constructor?
You get this error because the WikEdDiff object was cleared internally inside diff(), as shown in this section of the code:
def diff( self, oldString, newString ):
...
# Free memory
self.newText.tokens.clear()
self.oldText.tokens.clear()
# Assemble blocks into fragment table
fragments = self.getDiffFragments()
# Free memory
self.blocks.clear()
self.groups.clear()
self.sections.clear()
...
return fragments
If you just need the fragments, use the returned variable of diff() like this:
import WikEdDiff as WED
config=WED.WikEdDiffConfig()
w = WED.WikEdDiff(config)
f = w.diff("abc", "efg")
# do whatever you want with f, but don't use w
print(' '.join([i.text+i.type for i in f]))
# outputs '{ [ (> abc- ) abc< efg+ ] }'
I'm trying to get up and running using the TTreeReader approach to reading TTrees in PyROOT. As a guide, I am using the ROOT 6 Analysis Workshop (http://root.cern.ch/drupal/content/7-using-ttreereader) and its associated ROOT file (http://root.cern.ch/root/files/tutorials/mockupx.root).
from ROOT import *
fileName = "mockupx.root"
file = TFile(fileName)
tree = file.Get("MyTree")
treeReader = TTreeReader("MyTree", file)
After this, I am a bit lost. I attempt to access variable information using the TTreeReader object and it doesn't quite work:
>>> rvMissingET = TTreeReaderValue(treeReader, "missingET")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/user/ROOT/v6-03-01/root/lib/ROOT.py", line 198, in __call__
result = _root.MakeRootTemplateClass( *newargs )
SystemError: error return without exception set
Where am I going wrong here?
TTreeReaderValue is a templated class, as shown in the example on the TTreeReader documentation, so you need to specify the template type.
You can do this with
rvMissingET = ROOT.TTreeReaderValue(ROOT.Double)(treeReader, "missingET")
The Python built-ins can be used for int and float types, e.g.
rvInt = ROOT.TTreeReaderValue(int)(treeReader, "intBranch")
rvFloat = ROOT.TTreeReaderValue(float)(treeReader, "floatBranch")
Also note that using TTreeReader in PyROOT is not recommended. (If you're looking for faster ntuple branch access in Python, you might look in to the Ntuple class I wrote.)
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.
