I think this issue occurs because the REPL assumes each line has a maximum width equal to the terminal width. |

while trying to recreate the bug found another weird bug in windows terminal (python V3.13.3) STOUT's last line is prented in next prompt area (tried with larger number and it always happens only with the last line) 20250525-0620-56.8910328.mp4 |
