how do i use the variable in “tx”

ps:
>>> x = 200

in /obj/geo1/tx ; i don't know how to put the x variable in tx.

i try:
hou.ch(x)
hou.ch($x)
hou.ch(“x”)
hou.ch(“$x”)
$x
x
tx = x


can some one tell what command should i use to using Python HOM to input variable please ?

In your case you are attempting to access a variable declared in the global scope in a parameter. To do this you need to import the main module in your parameter. Putting the following into your will work.

import __main__
return __main__.x
