If you really want to make something like this work you can define a
class that would work like this:
vars = funkyclass()
varname = 'x'
vars[varname] = value
But this is clearly a design mistake. Either you know the names of the
variables when you write the code or you do not. If you know them you
can simply assign them directly. If you do not know them then you can't
put them in the code to read their values anyway, and what you need is
just a regular dictionary.
