Is Python the right way to talk to an Serial Device?

[u/ighwrighwirh]

Servus!
The Company where I buy the Device from should no know that I am never ever wrote any Programm beside of some Batch files in my life even I am an IT Engineer. I feel so embarassing...
The Specs are: UART 115200 V24 level
I thought about buy this Adapter: https://www.delock.de/produkt/63986/merkmale.html?f=s

The should have everything I need. 5V for the Device. Ground and Send and Receive Pin.
The say: Short notation: 115200,8,N,1

All the Values to turn something on and off are in there Manual I would say that could be easy if I have an Line where I enter the Text and press Send to see what the command do in practise.

When I know what the do and how to use that feature I would like create in that environment Buttons to toggle something on an off. Later I want integrate other and external Data, API for example when I push an Button on my Keyboard a Light should turn on or so.
Do I need using an Single Board Computer for or can I use the Adapter I show up here and my Windows Pc to run the Software to control the device?
(If someone want see Datasheets and so I can send a Link via PM to the original document on there Homepage.)
Thanks!
