How to find steam executable path in Python

Keep in mind that this code was made for a personal project so it will definitely have some unnecessary lines and bad code, but it works

Also please make comments about any updates to the code you made, so I can improve this post to save more people time (things like bug fixes, more paths in the possible paths method, comments, and support for Linux (should be doable with a few changes) or Mac).
About that, This code is made for Windows but with only a few slight changes (import error handling, disabling the registry method if on Linux, and updating the shortcut method to work with Linux's filesystem) it should work with Linux.
Improvements to this post would also be appreciated as English is not my first language so I definitely made some stupid mistakes.

import os
import winreg
import win32api

def read_reg(ep, p = r"", k = ''):
    try:
        key = winreg.OpenKeyEx(ep, p)
        value = winreg.QueryValueEx(key,k)
        if key:
            winreg.CloseKey(key)
        return value[0]
    except Exception as e:
        return None
    return None

Path1 = "{}\\Microsoft\\Windows\\Start Menu\\Programs\\Steam\\Steam.lnk".format(os.getenv('APPDATA'))
if os.path.exists(Path1):
    import sys
    import win32com.client 

    shell = win32com.client.Dispatch("WScript.Shell")
    shortcut = shell.CreateShortCut(Path1)
    Path1Res = shortcut.Targetpath
else:
    Path1Res = False
Path2 = str(read_reg(ep = winreg.HKEY_LOCAL_MACHINE, p = r"SOFTWARE\Wow6432Node\Valve\Steam", k = 'InstallPath'))+r"\steam.exe"
Path3 = str(read_reg(ep = winreg.HKEY_LOCAL_MACHINE, p = r"SOFTWARE\Valve\Steam", k = 'InstallPath'))+r"\steam.exe"
if not os.path.exists(Path2):
    Path2 = None
if not os.path.exists(Path3):
    Path3 = None
PossiblePaths = [r"X:\Steam\steam.exe", r"X:\Program Files\Steam\steam.exe", r"X:\Program Files (x86)\Steam\steam.exe"]
ValidHardPaths = []
for Drive in win32api.GetLogicalDriveStrings().split('\000')[:-1]:
    Drive = Drive.replace(':\\', '')
    for path in PossiblePaths:
        path = path.replace("X", Drive)
        if os.path.exists(path):
            ValidHardPaths.append(path)
if len(ValidHardPaths) == 0:
    ValidHardPaths = ["None"]
print("Registry64: " + str(Path2)+"|"+ "Registry32: "+ str(Path3)+"|"+ "Start Menu Shortcut: "+ str(Path1Res)+"|"+ "Possible Locations: " + ', '.join(ValidHardPaths)+"|")

As I said earlier, this code was for a personal project, so there are no things like comments, but ill still try to explain the code the best I can.
Method 1: (start menu shortcut) works by first trying to find the steam start menu shortcut, if it exists it will read the destination and add 'steam.exe' to it, then it will check if the path is valid (source: https://stackoverflow.com/a/571573/14132974).
Method 2: (registry) works by attempting to find the steam registry path and reading the key: "InstallPath", adding 'steam.exe' to it, and then checking if the path is valid. It will also do the same using the Steam32 registry path (source: https://tutorialexample.com/python-read-and-write-windows-registry-a-step-guide-python-tutorial/, https://github.com/NPBruce/valkyrie/issues/1056).
Method 3: (possible paths) is fairly simple, there is a list of paths where there is a big chance Steam might be installed, it will check this path for every drive in the system and check if the path is valid (source: https://stackoverflow.com/a/827397/14132974).

Lastly, support:
This code obviously supports having a valid path found with a method, if not it will become 'None', it also supports multiple paths being found in the 'possible paths' method
I think that's all, Cheers!
