Python code errors

I am trying to run two codes, attached, and receiving the following error messages:

at line 11: if app.ProjectName != project_name:

The first code to generate the antenna:

if app.ProjectName != project_name:
    app.NewProject(project_name)


if app.ActiveDesignName != design_name:
    app.InsertDesign("HFSS", design_name)

app.SetActiveDesign(design_name)

design = app.GetActiveDesign()
