How to check if a parent.SHORTCUT exists?

General TouchDesigner Discussion

From inside a parameter expression, is there a way to check if a parent.SHORTCUT exists?

Thanks in advance

hasattr( parent, “shortcut”) should work. It might catch some other attribute but should be ok?

Thank you. Works fine

For a more general solution you may also look at tdu.tryExcept:

Example:
tdu.tryExcept(lambda: 1/me.par.w, 0.0) # second argument is simply 0.0
