Am getting a problem with mine I'm using pycharm and when i try running it. It's display comes differently the BoxLayout are all displaying on the bottom of the viewing window.... Im using kivy --version (1.11.1)
Since PEP8 uses the CapWords convention for class names, technically SigninApp should be SignInApp. Personally, I don't like the look of either, so I went with LoginApp and LoginWindow for my classes. This just looks a lot better in my opinion. If anyone watching this video is serious about programming, it may be worth your while to look into PEP8. www.python.org/dev/peps/pep-0008/
