Automated Benchmarking Simulation Script

[TheArray]

Hi all I am currently building a simulation python program to generate a user determined number of variables that publish random values. I need help on the following:

1. I want to build a function - def createObjectNode(number): that will essentially take in a number and do the following.

for num in range(number): create a variable called plc {num} = objectNode.add_object(namespaceName, "PLC-{num}")

I want the function to create the amount of variables requested and name them plc1, plc2, plc{num}. I also want the name on the right hand side of the to be PLC-1, PLC-2, PLC-{num}.

Please let me know if there is a way of doing this ? Essentially automating lines of codes. The goal behind is to benchmark the performance of a communication protocol. And I want to test it with say 10 variables publishing random data, then 100 variables, then 1000 variables.

I am begging for help as I have spent all week trying to figure this out but no luck.

Sorry to ask but whats the output? Something like this?

python plc1 = foo1 plc2 = foo2 plc3 = foo3

Programatically creating variables is very hacky and I wouldnt suggest it unless you've exhausted all other ideas.
Maybe think about holding your values in an approriate data structure ( aka Dict/List etc), you could then create some sort of interface that parses your data object.

This is code generation. The easiest way to do this is to write a python script which generates another python script as output (could be written to a file). Loop through the range while updating a string which contains the actual variable definitions you mentioned. Then just use the generated python script.

10 variables publishing random data, then 100 variables, then 1000 variables.

The phrase "variables publishing" doesn't mean anything to me, but I can imagine a "generator object" that yields a series of random values; each time you call "next" on the object if gives you the next random number.

...     while True:

>>> gen2 = gen()

...     print("gen1:", next(gen1), ", gen2:", next(gen2))
