[Ironpython-users] Scripting Ansys with IronPython - Unable to call values from dictionary

[刘振海]

Hi,
I think you should check the type of verifiedValues like "type(
verifiedValues)"
then use the dir function to check the content of verifiedValues.
maybe try to use new_verifiedValues=dict(verifiedValues)
Hope it will help!
