manim does not create an output file

If I run
python -m manimlib scene.py ket_bra
My scene renders fine into the interactive viewer, but I don't get any output file, the terminal prints the following
ManimGL v1.6.1
[13:55:48] INFO Using the default configuration file, which you can modify in `c:\users\miika\manim\manimlib\default_config.yml` config.py:323

If I add the parameter -p to the command then the interactive window remains blank and doesn't render the scene and in no case do I get an output file which is what I'm looking for and the terminal output is the same as before. Also if it's of note the background is grey, even tho it appears to be black in all samples that I can find. I have absolutely no idea what's going on as I can't find anybody else with a similar issue. I'm using windows 10 and v1.6.1 of 3b1b manim. The scene in this case is as follows (though this issue appears regardless of what the scene is)
from manimlib import *
class ket_bra(Scene):
def construct(self):
ket_q0 = Tex(r"|q_0\rangle")
ket_0 = Tex(r"|0\rangle")
ket_1 = Tex(r"|1\rangle")
ket_0_v2 = Tex(r"|0\rangle")
ket_1_v2 = Tex(r"|1\rangle")
ket_0_v3 = Tex(r"""|0\rangle=\begin{pmatrix}
1\\
0
\end{pmatrix}""")
ket_1_v3 = Tex(r"""|1\rangle=\begin{pmatrix}
0\\
1
\end{pmatrix}""")
bra_kets = VGroup(ket_q0, ket_0, ket_1).arrange(RIGHT, buff=1)
v_bra_kets = VGroup(ket_0_v2, ket_1_v2).arrange(RIGHT, buff=1.5)
bra_kets_def = VGroup(ket_0_v3, ket_1_v3).arrange(RIGHT, buff=1.5)
self.play(Write(ket_q0), Write(ket_0), Write(ket_1))
self.wait(0.5)
self.play(FadeOut(ket_q0))
self.play(Transform(ket_0, ket_0_v2), Transform(ket_1, ket_1_v2))
self.wait(1)
self.play(Transform(ket_0, ket_0_v3), Transform(ket_1, ket_1_v3))

Well I fixed the problem, without fixing the problem, I just switched to the community edition of manim and it works exactly as intended, so if you encounter the same problem and you're using 3b1b manim version, I reccomend just switching to the community version of manim, they are mostly functionally equivalent, but the community edition appears to be less buggy at least for me. Here's a super easy installation guide for it https://docs.manim.community/en/stable/installation/windows.html
However, I won't mark this as the best answer, because I didn't really solve the problem, and I still get the following warning and have no idea what it is. However, it appears to not affect functionality so it's fine, lol.

Windows Solution
Create TempLatex directory in C drive
Find manimlib/default_config.yml in the manim (manimgl version) directory and open it with a text editor
Modify line 18: before: temporary_storage: "" after: temporary_storage: "C:/TempLatex "
Save

Rename a window

Iam trying to get the HWND of multiple windows called the same, and i thought the easy way would be to rename the one i found and search again, but it seems iam not allowed to rename it the way i want.
This is what i have tryed
import win32gui
import win32api
test = win32gui.FindWindow(0, "notepad")
win32gui.SetWindowText(test, "testname")

I have done this in my old project. may be this could help you. use this example as your reference
def UpdateControl_FromValue(self):
name_val = self.GetOptionValue(self.option_folder_name)
id_val = self.GetOptionValue()
self.in_setting_name = True
if id_val:
self.SetOptionValue("", self.option_folder_name)
opt_processors.FolderIDProcessor.UpdateControl_FromValue(self)
else:
if name_val:
win32gui.SetWindowText(self.GetControl(), name_val)
self.in_setting_name = False

FindWindow can return an invalid handle (eg. when no windows matching the text is found). That could be your issue.
The win32gui module exposes win32gui.EnumWindows (doc) that iterates top level windows. You can provide a custom callback that transform the window title.
In the following sample, I filter windows by title prefix, but you could implement a filter with regex, if that's more suitable for you.
import win32gui
def f(hwnd, more):
title = win32gui.GetWindowText(hwnd)
# print(f"{hwnd} - {title}")
prefix = 'notepad'
if title.startswith(prefix):
win32gui.SetWindowText(hwnd, title[len(prefix):])
win32gui.EnumWindows(f, None)

Select all elements of a listview in pywinauto using send_message

Need help to select all elements of a listview using send_message. I want this to work in RDP disconnected mode and hence using pywinauto's send_message api.
My code
from pywinauto import win32defines
app = Application().connect(path = pathToAppEXE)
lvitem = win32structures.LVITEMW()
lvitem.mask = win32defines.LVIF_STATE
lvitem.state = 1
lvitem.stateMask = win32defines.LVIS_SELECTED
app.window_(title_re = "Net Position.*").ListView.send_message(win32defines.LVM_SETITEMSTATE,-1,lvitem)
It does nothing. Maybe I am not getting the lvm flags correctly. Need assistance to fix the code.

Method .get_item(...) (see docs) should return _listview_item object with some available methods: some of them don't involve real click.
Maybe Remote Execution Guide is also useful.

How to assign a 2d libreoffice calc named range to a python variable. Can do it in Libreoffice Basic

I can't seem to find a simple answer to the question. I have this successfully working in Libreoffice Basic:
NamedRange = ThisComponent.NamedRanges.getByName("transactions_detail")
RefCells = NamedRange.getReferredCells()
Set MainRange = RefCells.getDataArray()
Then I iterate over MainRange and pull out the rows I am interested in.
Can I do something similar in a python macro? Can I assign a 2d named range to a python variable or do I have to iterate over the range to assign the individual cells?
I am new to python but hope to convert my iteration intensive macro function to python in hopes of making it faster.
Any help would be much appreciated.
Thanks.

LibreOffice can be manipulated from Python with the library pyuno. The documentation of pyuno is unfortunately incomplete but going through this tutorial may help.
To get started:
Python-Uno, the library to communicate via Uno, is already in the LibreOffice Python’s path. To initialize your context, type the following lines in your python shell :
import socket # only needed on win32-OOo3.0.0
import uno
# get the uno component context from the PyUNO runtime
localContext = uno.getComponentContext()
# create the UnoUrlResolver
resolver = localContext.ServiceManager.createInstanceWithContext(
"com.sun.star.bridge.UnoUrlResolver", localContext )
# connect to the running office
ctx = resolver.resolve( "uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext" )
smgr = ctx.ServiceManager
# get the central desktop object
desktop = smgr.createInstanceWithContext( "com.sun.star.frame.Desktop",ctx)
# access the current writer document
model = desktop.getCurrentComponent()
Then to get a named range and access the data as an array, you can use the following methods:
NamedRange = model.NamedRanges.getByName(“Test Name”)
MainRange = NamedRange.getDataArray()
However I am unsure that this will result in a noticeable preformance gain.

Adding testcase results to Quality Center Run from a outside Python Script

I want to try to add all the step details - Expected, Actual, Status,
etc. to a QC Run for a testcase of a TestSet from a Python Script
living outside the Quality Center.
I have come till here (code given below) and I don't know how to add
Step Expected and Step Actual Result. If anyone knows how do it,
please help me out!! Please, I don't want any QTP solutions.
Thanks,
Code-
# Script name - add_tsrun.py
# C:\Python27\python.exe
# This script lives locally on a Windows machine that has - Python 2.7, Win32 installed, IE8
# Dependencies on Windows Machine - Python 2.7, PythonWin32 installed, IE8, a QC Account, connectivity to QCServer
import win32com.client, os
tdc = win32com.client.Dispatch("TDApiOle80.TDConnection")
tdc.InitConnection('http://QCSERVER:8080/qcbin')
tdc.Login('USERNAME', 'PASSWORD')
tdc.Connect('DOMAIN_NAME', 'PROJECT')
tsFolder = tdc.TestSetTreeManager.NodeByPath('Root\\test_me\\sub_folder')
tsList = tsFolder.FindTestSets('testset1')
ts_object = tsList.Item(1)
ts_dir = os.path.dirname('testset1')
ts_name = os.path.basename('testset1')
tsFolder = tdc.TestSetTreeManager.NodeByPath(ts_dir)
tsList = tsFolder.FindTestSets(ts_name)
ts_object = tsList.Item(1)
TSTestFact = ts_object.TSTestFactory
TestSetTestsList = TSTestFact.NewList("")
ts_instance = TestSetTestsList.Item(1)
newItem = ts_instance.RunFactory.AddItem(None) # newItem == Run Object
newItem.Status = 'No Run'
newItem.Name = 'Run 03'
newItem.Post()
newItem.CopyDesignSteps() # Copy Design Steps
newItem.Post()
steps = newItem.StepFactory.NewList("")
step1 = steps[0]
step1.Status = "Not Completed"
step1.post()
## How do I change the Actual Result??
## I can access the Actual, Expected Result by doing this, but not change it
step1.Field('ST_ACTUAL') = 'My actual result' # This works in VB, not python as its a Syntax error!!
Traceback ( File "<interactive input>", line 1
SyntaxError: can't assign to function call
Hope this helps you guys out there. If you know the answer to set the
Actual Result, please help me out and let me know. Thanks,
Amit

As Ethan Furman answered in your previous question:
In Python () represent calls to functions, while [] represent indexing and mapping.
So in other words, you probably want to do step1.Field['ST_ACTUAL'] = 'My actual result'

Found the answer after a lot of Google Search :)
Simple -> Just do this:
step1.SetField("ST_ACTUAL", "my actual result") # Wohhooooo!!!!
If the above code fails to work, try to do the following:-
(OPTIONAL) Set your win32 com as follows- (Making ''Late Binding'')
# http://oreilly.com/catalog/pythonwin32/chapter/ch12.html
a. Start PythonWin, and from the Tools menu, select the item COM Makepy utility.
b. Using Windows Explorer, locate the client subdirectory (OTA COM Type Library)
under the main win32com directory and double-click the file makepy.py.
Thank you all...
