Question

linux

Where is the python system library stored on Linux (not modules, but of type int () and so on)?

Answer 1

"of type int() and so on" are not library functions, but built-in ones. Accordingly, they are "stored" in the interpreter code.

Answer 2

ls /usr/lib/python*
You can strace see which system calls and libraries are accessed:
strace /usr/bin/python3.8

Answer 3

import sys
print(sys.path)
