Is it safe to paste my Python code into an online formatter?
Code is sent to a secure backend over HTTPS and processed transiently for formatting. However, as a best practice you should avoid sending passwords, API keys, personal data or highly confidential business logic to any online tool. For sensitive projects, run Black locally or inside your own CI environment instead.

r/learnpython on Reddit: Easy, free to use online formatter for Python code with configuration options?
July 13, 2024 -

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.
