chipmunk | Pure Go Physics engine based on chipmunk-physics | Animation library

I have written the below program which is aimed at simulating a weight balancing experiment using knife edge. however, the weight of the box is not affecting the segment as shown when simulated. I am currently new on learning how to code with pymunk. kindly help me out on this

my first ever question on Stack Overflow as I'm learning Python (with absolute no programming background whatsoever).

I'v tried finding an answer but I don't undestand where my error is. If the question is inappropriate I will delete it and I apologize.

I'm following a MOOC about Python. Very early, when learning about parameters and functions I came across an error I don't understand.

Here is the code, while running it it says "SyntaxError: multiple statements found while compiling a single statement"

I have a .mp3 file that contains just voice and I would like to adjust the speed (slower or faster) while maintaining the same clarity. No chipmunks! Then write out the modified file to disk. In order to do this, I am trying to use the AVAudioEngine Framework but am a complete N00B to the framework. All the examples, I have found, are geared to modifying music or recording voice then playing it audibly. I just want to convert to a different speed and have it spit out the modified file. This was all I could figure out so far, I documented my confusion in the comments of the code.

I only want to show Chip, but I get both Chip AND Dale. It doesn't seem to matter which 32 bit character I put in, tkinter seems to duplicate them - it's not just chipmunks.

I'm thinking that I may have to render them to png and then place them as images, but that seems a bit ... heavy-handed.

Any other solutions? Is tkinter planning on fixing this?

i try to concat multiple videos to one video and add an background music to it.

for some reason the background music is perfectly added to the output video but the audio of each part of the output is speed up to a chipmunk version of the video itself. this results in an output video of 7 minutes with about 5 minutes of silence since everything is so fast that all the audio finishes after about 2 minutes.

my command is:

ffmpeg -safe 0 -i videolist.ffconcat -i bg_loop.mp3 -y -filter_complex "[1:0]volume=0.3[a1];[0:a][a1]amix=inputs=2" -vcodec libx264 -r 25 -filter:v scale=w=1920:h=1080 -map 0:v:0 output.mp4

i tried to remove the background music (since i wasn't able to loop it through the video i thought maybe that's the issue) and still.. all the audio of the video clips is still speed up resulting in chaotic audio at the beginning and silence at the end.

my video list looks like this:

I am using pandas and pulling information from excel into a list, that part works great and my lists are coming back and I can print them out just fine with no NaN or errors.

However when I go to iterate through them I am encountering an issue with the string index being out of range after the first iteration or when itr is 1 as it prints the first one just fine then errors at the line site = site[itr].

The site array or list if you will which is comprised of numeric values. I get the count of the number of rows pulled from excel as the index limiter called toSend.

I added site = [str(i) for i in site] because I was getting the error that the int object is not subscriptable.

I'm not sure where I turned left at, any help is very much appreciated.

I am trying to learn PyMunk library and I used the example from their website. Here is a code:

I'm writing a function that its input is a text file as below:

I am trying to write a function that uses indices that takes key-value pairs and stacks them.

Here is my data:
