[Twisted-Python] Error using "python -m twisted.conch.stdio" command in command prompt

[Melanie Molifie]

Hi guys

I'm new to twisted and would appreciate some beginner guidance.

I'm trying to use the "python -m twisted.conch.stdio" command in command
prompt but it does not work and gives the following error:

C:\WINDOWS\system32>python -m twisted.conch
C:\Users\Melanie\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\python.exe:
No module named twisted.conch.*main*; 'twisted.conch' is a package and
cannot be directly executed

*I'm hoping that this will solve the rest of the error messages I'm having.
I want to eventually be ably to run :*

>>> from twisted.names import client
>>> client.getHostByName('www.example.com')
<Deferred at 0xf5c5a8 waiting on Deferred at 0xf5cb90>
>>> _
<Deferred at 0xf5c5a8 current result: '2606:2800:220:6d:26bf:1447:1097:aa7'>

>>> client.lookupMailExchange('twistedmatrix.com')
<Deferred at 0xf5cd40 waiting on Deferred at 0xf5cea8>
>>> _
<Deferred at 0xf5cd40 current result: ([<RR name=twistedmatrix.com
type=MX class=IN ttl=1s auth=False>], [], [])>

*The aim is to get the deferred responses as shown in previous code, but
all I get is:*

>>> from twisted.names import client
>>> client.getHostByName('www.example.com')
<Deferred at 0x263d27b9dc8 waiting on Deferred at 0x263d27b9f48>
>>> _
<Deferred at 0x263d27b9dc8 waiting on Deferred at 0x263d27b9f48>
>>> client.lookupMailExchange('twistedmatrix.com')
<Deferred at 0x263d27c6a88 waiting on Deferred at 0x263d27c6c08>
>>> _
<Deferred at 0x263d27c6a88 waiting on Deferred at 0x263d27c6c08>

Please help. I'm trying to send this to the twisted mailing group. If I'm
wrong please nudge me in the right direction.

Thanks in advance.
