The call.func parameter type of the local_python_executor.evaluate_call function might be ast.Subscript

fix for #181.
btw:

   elif name.id in custom_tools:
        return custom_tools[name.id]

to allow a list of objects, like :

def my_func():
    do_smth()
list = [my_func, my_func] 

Now we get the error:
The variable my_func is not defined.
