i know only assembly or something in c,

but my friends using python, the python easy language.

so why i knowing which MPU supported language?????

It is an odd question because it not limited, pretty much anything with either a compiler or interpreter is going to be an option. ​People port languages they like, some may be popular and others may see little to no uptake.

C++: yes, supported.

STM32 chips that have enough memory can work with Micropython https://micropython.org

If you don't know Python, it is definitely worth for you to look at. Very satisfying.

Other notable variant is Duktape https://duktape.org - for these who prefers Javascrpt.
