Solve the following python programming problem given the following code:
def create_project() : 
    project = Project ('/') 
    project.build_depends_on ('testingframework') 
    project.depends_on ('sometool') 
    project.depends_on ('pyassert', url = 'https://github.com/downloads/halimath/pyassert/pyassert-0.2.2.tar.gz') 
    project.name = 'Spam and Eggs' 
    project.version = '1.2.3' 
    project.summary = 'This is a simple integration-test for distutils plugin.' 
    project.description = 'As you might have guessed we have nothing to say here.' 
    project.authors = [Author ('Udo Juettner', 'udo.juettner@gmail.com'), Author ('Michael Gruber', 'aelgru@gmail.com')] 
    project.license = 'WTFPL' 
    project.url = 'http://github.com/pybuilder/pybuilder' 
    def return_dummy_list() : 
        return ['spam', 'eggs'] 
project.list_scripts = return_dummy_list 
    project.list_packages = project 
    project.list_modules = return_dummy_list 
    project.set_property ('distutils_classifiers', ['Development Status :: 5 - Beta', 'Environment :: Console']) 
    project.install_file ('dir', 'file1') 
    project.install_file ('dir', 'file2') 
    project.include_file ('spam', 'eggs') 
    return project 

    
    

    Fix the buggy line: project.list_packages = project
assistant
#Here is Python program to fix the buggy line: project.

project.list_packages = return_dummy_list
