I just want to reformat everything so it's perfect. Is there anything like that in Python? What's the best?

I am searching for a formatter for Python3 which takes a few simple styling parameters and yet is very easy to use. All I found so far where tons of formatters, which ansolutely enforce one and only one formatting style.

Example input:

def deleteSubnet(ipAddress, cidrMask, interface = defaultNetworkInterface):
    if subprocess.run(["ip","a","d",ipAddress+"/"+cidrMask,"dev",interface], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL).returncode != 0:
        quit(color.red+" ERROR:"+color.stop+" IP could not be cleared. You need to manually remove "+color.blue+ipAddress+"/"+cidrMask+color.stop+" from "+color.blue+interface+color.stop+"!!! Terminating...")
    print(color.green+" Success: deleted IP "+color.stopcolor.blue+ipAddress+"/"+cidrMask+color.stop+" from interface "+color.blue+interface+color.stop+".")

Example output (NOT WANTED):

def deleteSubnet(ipAddress, cidrMask, interface=defaultNetworkInterface):
    if (
        subprocess.run(
            ["ip", "a", "d", ipAddress + "/" + cidrMask, "dev", interface]
            stdout=subprocess.DEVNULL,
            stderr=subprocess.DEVNULL,
        ).returncode
        != 0
    ):
        quit(
            color.red
            + " ERROR:"
            + color.stop
            + " IP could not be cleared. You need to manually remove "
            + color.blue
            + ipAddress
            + "/"
            + cidrMask
            + color.stop
            + " from "
            + color.blue
            + interface
            + color.stop
            + "!!! Terminating..."
        )
    print(
        color.green
        + " Success: deleted IP "
        + color.stopcolor.blue
        + ipAddress
        + "/"
        + cidrMask
        + color.stop
        + " from interface "
        + color.blue
        + interface
        + color.stop
        + "."
    )

Yes it is ugly. Does not matter. If reddit does word-wrap the lines, it will be horrible. But if the line just overflows, it just looks great for me.

All I want to do is a simple tool that understands the indentations and allows me to configure a target indentation. I do not care for the standard that tools like pylint try to enforce - i dislike it.

However what is way worse than not breaking lines, is uneven indentations. And that I need to fix - but please not manually. Is there an easy to use tool, that can fix my *variable* indentations to exactly 2 spaces per indent without changing the rest of the content of the lines? (yes I want 2 spaces, period)

For javascript there are amazing tools, like beautifier.io which handles it perfectly. Why can't I find something like that for python? And yes, I prefer a simple online tool actually, that does not require a login or download.

As to why it is uneven: It is a copy&paste collection from different sources.

Thanks for your help.
