argparse | line argument parsing inspired by Python 's argparse package | Parser library

Does anyone know if the python3 command on Linux can have some sort of SOME_NAMED_OPTION=filename.py after it rather than just calling python3 filename.py?

I have a job scheduling tool I'd like to execute a Python script with that's kind of dumb.

It can only run Linux CLI commands commandname param1 param2 param3 or as commandname AAA=param1 BBB=param2 CCC=param3.

There's an existing business convention of putting filename.py as param #1 and then just making sure your script has a lot of comments about what the subsequent numerically ordered sys.argv list members mean, and you set the scheduling tool into its first mode, so it runs python3 filename.py world mundo monde, but it'd be awesome to be able to name the scheduling tool's parameters #2+ so I can write more human-friendly Python programs.

With python3 -h I'm not finding a way to give a parameter-name to filename.py, but I thought I'd see if anyone else had done it and I'm just missing it.

It'd be cool if I could have my scheduling tool run the a command more like python3 --scriptsource=filename.py --salut=monde --hola=mundo --hello=world and then write filename.py to use argparse to grab hola's, hello's, and salut's values by name instead of by position.

When using python if you have say:

Error while installing manimce, I have been trying to install manimce library on windows subsystem for linux and after running

For me what I do is detect what is unpickable and make it into a string (I guess I could have deleted it too but then it will falsely tell me that field didn't exist but I'd rather have it exist but be a string). But I wanted to know if there was a less hacky more official way to do this.

Current code I use:

I was able to build a multiarch image successfully from an M1 Macbook which is arm64. Here's my docker file and trying to run from a raspberrypi aarch64/arm64 and I am getting this error when running the image: standard_init_linux.go:228: exec user process caused: exec format error

Editing the post with the python file as well:

I have a few arguments added to my argparse parser in my script as below:

I need an ArgumentParser, with a conflict handling scheme, that resolves some registered set of duplicate arguments, but raises on all other arguments.

My initial approach (see also the code example at the bottom) was to subclass ArgumentParser, add a _handle_conflict_custom method, and then instantiate the subclass with ArgumentParser(conflict_handler='custom'), thinking that the _get_handler method would pick it up.

This raises an error, because the ArgumentParser inherits from _ActionsContainer, which provides the _get_handler and the _handle_conflict_{strategy} methods, and then internally instantiates an _ArgumentGroup (that also inherits from _ActionsContainer), which in turn doesn't know about the newly defined method on ArgumentParser and thus fails to get the custom handler.

Overriding the _get_handler method is not feasible for the same reasons.

I have created a (rudimentary) class diagram illustrating the relationships, and therefore hopefully the problem in subclassing ArgumentParser to achieve what I want.

I (think, that I) need this, because I have two scripts, that handle distinct parts of a workflow, and I would like to be able to use those separately as scripts, but also have one script, that imports the methods of both of these scripts, and does everything in one go.

This script should support all the options of the two individual scripts, but I don't want to duplicate the (extensive) argument definitions, so that I would have to make changes in multiple places.
This is easily solved by importing the ArgumentParsers of the (part) scripts and using them as parents, like so combined_parser = ArgumentParser(parents=[arg_parser1, arg_parser2]).

In the scripts I have duplicate options, e.g. for the work directory, so I need to resolve those conflicts.
This could also be done, with conflict_handler='resolve'.

But because there are a lot of possible arguments (which is not up to our team, because we have to maintain compatibility), I also want the script to raise an error if something gets defined that causes a conflict, but hasn't been explicitly allowed to do so, instead of quietly overriding the other flag, potentially causing unwanted behavior.

Other suggestions to achieve these goals (keeping both scripts separate, enabling use of one script that wraps both, avoiding code duplication and raising on unexpected duplicates) are welcome.

I have a python file with no argparse implementation in its __main__, yet, I'm interested in having a look at the functions and modules implemented in it from the commandline. I'm tempted to write a function to perform such exploration but I wanted to find out first whether this is already available.

EDIT 1: to make it more concrete, I'm interested in names of functions and classes + their docs.

I am trying to digitize the kid's drawing into SVG or transparent png file format so that they can be used in Scratch. The white paper should be replaced by transparent background and all the drawing part should be preserved.

My plan is to get the outest contour of the drawing and generate a mask, then use the mask to get the drawing part without paper background.

The problem is the drawing may not consecutive which means there may have some small holes leading to break the entire drawing contour to many many small contours.

Now I want to concatenate the near outest contours to form a big outest contour for masking.

The original drawing and the processed result is attached.
