[BUG] rich.progress.track with stderr Console breaks print builtin

[ericfrederich]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

While using rich.progress.track configured with a Console instantiated with stderr=True, print statements also go to stderr.

I would expect rich to not hijack the default behavior of print.

I understand I myself can use console.print() in my own code but I have no control over 3rd party plugins or libraries.

Provide a minimal code example that demonstrates the issue if you can. If the issue is visual in nature, consider posting a screenshot.

#!/usr/bin/env python

from rich.console import Console
from rich.progress import track

err_console = Console(stderr=True)
console = Console()


if __name__ == "__main__":
    for i in track(range(10), console=err_console):
        if i % 4 == 0:
            print(f"foo {i}")

    for i in range(10, 20):
        if i % 4 == 0:
            print(f"foo {i}")

What platform (Win/Linux/Mac) are you running on? What terminal software are you using?

I may ask you to copy and paste the output of the following commands. It may save some time if you do it now.

If you're using Rich in a terminal:

python -m rich.diagnose
pip freeze | grep rich

Linux VM via WSL2.

The magic of having a progress bar stuck to the bottom of the screen may well break some of your expectations. You may well have to compromise, unless you can propose how to accomplish this.

I hope we solved your problem.
