How to flexibly set each variant type when creating a ua server（add_variable）

[ryangu18]

Dear friends, I am a newbie. I am practicing using this library to create a ua server

I have a csv files, the third column is variant type, I want each tag to have different variant type, but I don't know the grammar,

for eachTag in TagList:
	
	Temp = await Param.add_variable(addspace, eachTag[0], 0.0,ua.VariantType.Double)  # 
	
	await Temp.set_writable()

I have get the value from the third column and save to eachTag[2], which is a string type. I want to change variant type from ua.VariantType.Double to eachTag[2]. How should I modify the program?

Thanks in advance for your help.

Just provide a dict such as:

datatype_to_variant = {
   'Float':  (0.0, ua.VariantType.Double),
   'Int32': (ua.Int32(0), ua.ua.VariantType.Int32),
   ....
}

def_val, datatype = datatype_to_variant[eachTag[2]]
Temp = await Param.add_variable(addspace, eachTag[0], def_val, datatype)  #
