Unfortunately, Windows console doesn’t allow it (and Ctrl-T trick doesn’t help) so I had to find a workaround. The intuition and language reference helped me to find out that the simple statements can be separated by semicolons like in C/C++ (however, these languages allow to separate all the commands, not the only simple ones).

It is not allowed to mix simple and compound statements, so the following command will not work: python -c "import os;
