Parsing Command Line Output In Windows With Python

I essentially want to get some values from a command like 'ipconfig', but when I print the output of the command I get alot of newline characters and spaces. Code I've Tried: >&

Solution 1:

We get the output, decode it so it's a str, then iterate over its lines.

We'll store each separate adapter as a dict in a dict named adapters.

In the output, preceding the details of each adapter is a line starting with "Ethernet adapter ". We get the adapter's name by splicing the line from after the string "Ethernet adapter " to just before the ":" which is at index -1.

After that, it is assumed any line with " : " in it has details about the current adapter. So we split the line at " : ", clean it up a bit, and use them as key/value pairs for our current_adapter dict which we created earlier.

import subprocess

adapters = {}
output = subprocess.check_output("ipconfig").decode()

for line in output.splitlines():
    term = "Ethernet adapter "
    if line.startswith(term):
        adapter_name = line[len(term):-1]
        adapters[adapter_name] = {}
        current_adapter = adapters[adapter_name]
        continue

    split_at = " : "
    if split_at in line:
        key, value = line.split(split_at)
        key = key.replace(" .", "").strip()
        current_adapter[key] = value



for adapter_name, adapter in adapters.items():
    print(f"{adapter_name}:")
    for key, value in adapter.items():
        print(f"    '{key}' = '{value}'")
    print()

Output:

    'Link-local IPv6 Address' = 'fe80::...'
    'IPv4 Address.' = '192.168.255.255'

    'Default Gateway' = '192.168.255.255'
