Alternative to dynamic variable names

[catosp]

Hello !

This is a clasical example of pyvisa program:

import pyvisa
rm = pyvisa.ResourceManager()
rm.list_resources()
('ASRL1::INSTR', 'ASRL2::INSTR', 'GPIB0::12::INSTR')
inst = rm.open_resource('GPIB0::12::INSTR')
print(inst.query("*IDN?"))

Now, the problem is if I have a text file with multiple names and address of various instruments, something like this:

keithley,GPIB0::12::INSTR
lakeshore,GPIB0::11::INSTR
etc

How can I make the program from above to work without to dynamically create the variable with the name and address of each instrument from the file text?

I want to avoid this type of variable declaration:

rm = visa.ResourceManager()
vars()["lakeshore"] = rm.open_resource('GPIB0::11::INSTR')

Is possible?
Thank you!
