Calling on a Variable using other Variables

[jacknewport]

Is it possible to call upon a variable using other variables? For example if you have the name of a variable stored in another variable, could you call upon the first variable using the name of the variable stored in the other variable?

# The original variable
var1 = 'Z26'

var2 = 'Z'
var3 = '26'

# Is there a way to make this be equivalent to var1 = 'A1'?
var2 + var3 = 'A1'

Thanks!
