Почему seqprint не происходит после seqinput? ⇐ Python

[Anonymous]

Я новичок в Python, и у меня есть вопрос. Я определил функции seqprint и seqinput (см. скриншоты), которые прекрасно работают изолированно, но если я попытаюсь вызвать seqprint после seqinput (именно в этом порядке!), этого вообще не произойдет, в то время как, например. печать после того, как seqinput работает. Я не понимаю, почему, поэтому буду признателен за любую помощь.
Я ожидал, что seqprint произойдет нормально, как и раньше. Copilot побудил меня попробовать использовать sys.stdout.flush() между ними, но это ничего не дало (и должно произойти в любом случае из-за exit ChangeTerminalColor?)
