Python, PHP, Javascript, Java, C++, Go, Kotlin, Swift
For these programming languages, I understand the basic syntax, and acquaint the main characteristics and how to configure the development envionment.
I can develop simple applications and read other people's code.
Python is my main language.
I am familiar with the basic syntax of Python and do not google it when coding.
I am also familiar with Python's theoretical background and working principles, so there is no embarrassing situation when I talk to someone.

I am familiar with Python, PHP, and Javascript because they are currently used by my company.
However, I still have a habit of googling and coding whenever necessary without fully familiarizing myself with the syntax.
I am trying to code without googling for the basic syntax.
Java has been forgotten for over 5 years, but fortunately I am using Java in recent algorithmic lectures at Coursera.
C++ is being used to solve Google Code Jam problems, but I am not familiar with it because I have no experience in application development and I do not use it often.
I have not used Go and have only learned what language it is.
As for Kotlin, I had experience converting my own Android apps from Java to Kotlin, but it was a one-off.
As for Swift, I learned about base iPhone app development about 3 years ago, but I haven't experienced one cycle until application launch.
