Understanding stdin, stdout, stderr in Python

A lot of information, very good to watch after some previous videos about theory if in out and error streams in any OS.

0:00 I'm wondering if I need this, let's see.

I like to include a function function for printing to stderr so I don't need to keep typing the "file=": def eprint(*args, **kwargs): print(*args, file=sys.stderr, **kwargs) Most of the time when you're reading from stdin, you'll want to process one line at a time. If you don't need a context manager for some other reason, you can just treat sys.stdin as an iterable: for line in sys.stdin: if len(line) == 0: # End of file. Do final stuff here sys.exit(0) line = line.rstrip() Notice the rstrip(): reading includes the terminating (CR and) LF, and you usually don't want them as part of the data.

Useful video :) I learned something today :)

11:00 print has a flush parameter and I can avoid the printing the new line on print function calls.

Really useful

very helpful! thank you

thanks

I wonder if that works with logging....

Thanks 😊

Good job ❤

Thanks 🤍

Thx_.

POPos is no longer my fav distro. nvim is still running on version 6.1. You should try a WM in Arch. May be Hyprland or sway
