Re: Beginner question - class definition error

 from kivy.app import App
 from kivy.uix.label import Label
 
 class MyApp(App):
   def build(self):
 return Label(text='Hello World')
 
   if __name__ == '__main__':
 MyApp().run()

 

 I get this error when I run it:
 

 Traceback (most recent call last):
   File MinimalApplication.py, line 7, in module
 class MyApp(App):
   File MinimalApplication.py, line 12, in MyApp
 MyApp().run()
 NameError: name 'MyApp' is not defined

 How can I fix this please?
 
  Try removing beginning indentation 
  from 

if __name__ == '__main__': 
  
if __name__ == '__main__':

Unindent the 'if' statement. Currently, it's indented inside the class
definition, so MyApp isn't defined yet.

Thanks very much. That fixed it.
