Any time you find yourself wanting to indirectly define variables like
this, the chances are you would get better results (faster, less security
risks, easier to maintain, easier to re-factor and optimise, more
readable) if you change the algorithm.
Instead of:
x = "myVarName"
create_real_variable(x, some_value)
print myVarName
why not do something like this:
data = {"myVarName": some_value}
print data["myVarName"]
It is fast, clean, easy to read, easy to maintain, no security risks from
using exec, and other Python programmers won't laugh at you behind your
back <smiles>
