The script ends with exit code -4. does this number have a standard equivalent of some kind of exception, error?

Question

Python

everything that happens before the import of the library is executed, everything that happens after is not executed. the script ends with exit code -4
for example:

print('1')
import biblioteka
print('2')

will display only the number "1" no errors appear in the console.

Answer 1

use try...except and throw an error

Answer 2

I ran the script from the command line and got the error "Invalid instruction (core dumped)" or "illegal instruction (core dumped)" apparently exit code -4 corresponds to this error.
