Python Forum

Greetings!

I've read through a lot of posts and didn't manage to make it work.
My problem is that I'm unable to insert my variable in this statement:

roomNr= inputbox.get()

exp = 'setx roomNumber' roomNr
subprocess.Popen(exp, shell=True).wait()

Hi @coder420 ,
Welcome to the forum. Do you get an error message when you execute this? Something like:

Error:
  File "<input>", line 1
    exp = 'setx roomNumber' roomNr
                            ^
SyntaxError: invalid syntax

Always post error messages. What could be wrong with this line?

did you mean: exp = 'setx roomNumber' + roomNr
better expressed as: exp = f"setx roomNumber {roomNr}"
