Python output redirecting

When I'm running python3 interpreter on Linux machine and trying to redirect it's stdout to file like this, nothing happens:

user@workmachine:~$ python3 > python.txt
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
\>>>

File python.txt remains empty while interpreter is running as well as after it was closed. All it's output is still in terminal.

On the other hand, if I'm redirecting R interpreter the same way ( R > R.txt ) the result is as expected ( all output redirected to file, see nothing in terminal ).

What's the difference? Are python writes all it's output to another stream than stdout, or what?

For your case seems python send information to STDERR and not to STDOUT. So you should use redirect like:

user@workmachine:~$ python3 2> python.txt
