I’m trying to find a way to create and later reference a class that was defined not inside of actual python code.

I tried using the exec() function to execute lines of code that would create a class, but since python is an interpreted language I am under the assumption that this will not be a viable option. Here is the code that I tried:

def con(var, mt, todo):
  exec(f'''
class {var}:
  def __init__(self, x):
    self.x = x
  def {mt}(self):
    exec(todo)
{var} = Pleth{i}(7)
''')
