I am sorry, but I don't see how Demo1 could help me.
What I am looking for is the very, very basic of what Python4Delphi should offer to python programmers checking out Delphi.
Similar to a subprocess in python ...
sysCall = subprocess.run(f"""Your.exe {argument1} {argument2}""",shell=True, capture_output=True)
sysCallError = sysCall.stderr.decode('utf-8')
if len(sysCallError.strip()) > 0:
print(sysCallError)
sysCall = sysCall.stdout.decode('utf-8')
Continue to parse the sysCall output.
I will check out the DOSCommand package before moving on to something else.
