Can python used for app development? Can anyone suggest some apps based on python

Answer 1

Yes, but it can be quite a challange since most apps are built using Java or Kotlin in Android Studio.
Lots of famous apps are made using Python, such as: Instagram, Pinterest, Uber, Spotify ...
If you only want to try Android development within Python, checking the Kivy library for Python would be a good way to start.
If you want to mix Python (backend) and Java, Pycharm is great!

Answer 2

What is the type of app? Web app? Mobile app? Desktop app? Technologies may differ according to the goal.
Python can be used for the back end of a web app using frameworks like Django and Flask. Pinterest is a web app that uses Python. It can be used for desktop applications as well, I believe Sublime Text is created using C++ and Python.
Python is not really the best choice for mobile app development, it is possible, but it might be hard.
