tee-output is a Python library to tee standard output / standard error from the current process into a logfile. Unlike doing a shell redirection (i.e. python myscript.py 2>&1 | tee /tmp/log), tee-output preserves terminal semantics, so breakpoint() etc continue to work.

Basic usage:

from tee_output import tee
tee("/tmp/log.out", "/tmp/log.err")

After running the above, your standard output will stream to /tmp/stdout.out in addition to the terminal; your standard error will stream to /tmp/stdout.err in addition to the terminal.

You can also provide a list of locations to tee:

from tee_output import tee
tee(["/tmp/log.out", "/tmp/log.combined"], ["/tmp/log.err", "/tmp/log.combined"])

This will additionally create a file /tmp/log.combined which contains the interleaved standard output and error, such as you see in your terminal.
