Question

Python

I would like to know
Is it worth learning java and objective-c to create mobile applications if you know Python well?
many applications are written in python for Android and ios, etc. at a high level
It is worth studying both Java and IOS, If python can be written in both platform forms, unlike IOS
I understand that you can study kaka for general development, or is it still worth it

Answer 1

I do not understand you.
ps IMHO Java bucket head.

Answer 2

How do we know if you want to write for Android and iOS?
If you want, then it is necessary. If you don't want to, then no.

Answer 3

At the moment, python for mobile platforms is underdeveloped. Those. under android it is desirable to write in Java, and under iOS it is desirable to write in Swift or Objective-C (I think swift is now preferable for new applications).
There are also cross-platform frameworks such as phonegap( phonegap.com ), but to be honest, I was not interested in what opportunities there are.

Answer 4

If you want to write high-performance applications for different platforms, then look towards C# + Xamarin.
