eval evaluates an expression, not a statement. For that, you would use exec.

If you're just trying to import though, then you don't need it at all.
Use the importlib.import_module function instead to import a module
determined at runtime. This is more secure than eval or exec, which
can cause any arbitrary Python code to be executed.
