Hey There,
Can somebody explain please why this code works fine:
hou.node("/obj/").createNode('geo', 'test')

But this does not?
name = hou.ui.readInput('name')
hou.node("/obj/").createNode('geo', name)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.390/houdini/python2.7libs\houpythonportion\", line 1035, in decorator
    func, *args, **kwargs
  File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.390/houdini/python2.7libs\", line 45, in executeInMainThreadWithResult
    return _queueDeferred(code, args, kwargs, block=True)
  File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.390/houdini/python2.7libs\", line 104, in _queueDeferred
    raise exc_info[1]
TypeError: in method 'Node_createNode', argument 3 of type 'char const *'

Basically it generates error if i let user set custom name for the node via readInput() method.
The problem is probably simple but i can’t sort why...

Thanks for any help!

returns a tuple where the string is the second element. So you should use:

hou.node("/obj/").createNode('geo', name[1])
