stdin, stdout and stderr — what every Python developer needs to know

In this video, we’ll be looking at one of the most important yet underrated topics in Python — the standard input, output and error streams (stdin, stdout, stderr).
You’ll learn how `input()` and `print()` actually work, why errors are output separately, what stream redirection is, and why understanding this topic will come in handy not only in job interviews but also in real-world development.
The video is accompanied by simple diagrams and practical code examples.
