redirecting print to a a file

[AndyL]

Hi,

Can I redirect print output, so it is send to a file, not stdout.

I have a large program and would like to avoid touching hundreds of print's.

Thx, Andy

And what if I want to still send the output to stdout and just a log it
in the file as well?

Change sys.stdout to a file object.

I can suggest using the logging module instead of print. It's much
more flexible than prints, and well suited for large programs.

Thx for the hint. I will look into that.

$ python some_program.py | tee output.log

Or write a class that has a write() function and outputs to a file and
to the original value of sys.stdout (IIRC that's in sys.__stdout__)

Thx again. Python is cool, do that in C++ or Java :-)

Yes, thats obviously true ;-)

$> javac someprogram.jav a;
$> java someprogram | tee output.log

$> g++ someother.cpp -o someother
$> ./someother | tee output.log

SCNR,
