Hello, suppose in a .py using sdk I have my_var1 = 'prefix' then in the workflow I get at runtime another my_var2 that for example has the attribute my_var2.name that equals "suffix" Then I want to define a new variable my_var3 with value "prefix_suffix", where the string "suffix" is known only at runtime, how can I get it? my_var3 = ??? Can I use something similar to what I do when using the print function? print ("My storage domain is %s..." % sd.name) ? Thanks, Gianluca
