redirect and python

[questions?]

I am calling system command in python by os.system()

I do, os.system("wget http://blah blah blah")

then I run the program by ./programname >redirected file
The things put to screen doesn't redirect to the file I want.

What's the trick in here?

Thanks

What do you see on screen? What do you want to redirect to the file?

What's the trick in here?

Giving us useful information.

the ">" operator redirects standard output only, but wget prints stuff to the
standard error channel.

What's the trick in here?

the wget documentation explains how to redirect wget output. if you don't
have the manual page, you can do

wget --help

to get a list of options. see the section "Logging and input files" for the options
you need.

Why don't you use urllib(2) directly in Python?
