desktop pc, win 10 , python 3.11, kivy 2.2
Hello. I am trying to run this code to confirm setup before I dive into python and kivy trying to achieve my goal.
The code is from an slightly changed example, viewing a youtube video.
The result should show a map beeing able to zoom and a position on map.
Any wizzards out there who can help me code to work?
Is this error due to wrong setup of python (no indication during setup of erroor),or programming?
Thank you for any guideance.
Here is the code:
import kivy
kivy.require('2.2.0') # replace with your current kivy version !
from kivymd.app import MDAppApp
from kivy_garden.mapview import MapView
class MyApp(MDApp):
def build(self):
mapview = MapView(zoom=10, Lat=36, Lon=-115)
return mapview
MapViewApp().run()[error]IndentationError: expected an indented block after function definition on line 10[output]None observed[/output][/error]

The error says it cannot find a module named "kivymd". Did you install kivymd? Installing kivy does not install kivymd.
When you type "pip list" in a command shell, does it list kivymd?

No it wasnt listed. so I installed it ver.1.1.1
Running this code
from kivymd.app import MDApp
from kivy_garden.mapview import MapView
class MyApp(MDApp):
def build(self):
mapview = MapView(zoom=10, Lat=36, Lon=-115)
return mapview
MapViewApp().run()gives new error:
Error: File "d:\mapfiler\map.py", line 16
MapViewApp().run()

I tried to change code to:
[python][
from kivymd.app import MDApp
from kivy_garden.mapview import MapView
class MyApp(MDApp):
def build(self):
mapview = MapView(zoom=10, Lat=36, Lon=-115)

More indentation errors.
In Python, indenting serves the same purpose as {} in C. It creates blocks of code. If your code was written using {} for blocking, it would look like this:
from kivy.config import Config
Config.set('kivy','keyboard_mode','systemanddock')
from kivymd.app import MDApp
from kivy_garden.mapview import MapView
class MyApp(MDApp):
{
def build(self):
{
mapview = MapView(zoom=10, Lat=36, Lon=-115)
return mapview
if __name__ == '__main__':
{
MyApp().run()
}
}
}Maybe this makes it easier to see that your code does not make any MyApp objects. The only code that makes a MyApp object is deeply embedded in the build method of the MyApp class.
Also, your indenting is all over the place. Convention is every indent level is 4 spaces deeper than the previous level.
Maybe you should work through some kivy totorials. You cannot have success if you don't understand your tools.

Thanks for input. You are right. I just thought I should try an example from a youtube video before I dived into more suitable beginner levels. Was not even aware of the indenting. I will start with Python then Kivy and hopefully end up handling maps, Thanks for help and see You later. Regards
