[Python] How to verifying whether a file has valid signature in python?

I want to verify signature code in python with the only input is path/to/file

All other sources I've consulted need individual signature files but I only want to take as input a single file (can be .exe or .dll)

I've tried to write code purpose to verify if a file has a valid signature via window powershell

def is_valid_Sig(path:str):
if os.path.exists(path):
command = f"Get-AuthenticodeSignature \"{path}\""
result = subprocess.run(["powershell.exe", command], capture_output=True)
result = str(str(result.stdout) + str(result.stderr))

if " Valid " in result:
return 1
else: return 0
else: return -1


Is there anyway to do it without using cmd or powershell ? Please help me, thank you very much :>
