How to clear python console (i.e. Ctrl+L command line equivalent)
Question: OS = Linux

    
    
    [boris@E7440-DELL ~]$ uname -a
    Linux E7440-DELL 3.17.4-200.fc20.x86_64 #1 SMP Fri Nov 21 23:26:41 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
    

From python console (Spyder 2.2.4, Python 2.7.5 64bits, Qt 4.8.5) it is seen
as:

    
    
    >>> import os
    >>> print(os.name)
    posix
    

I'm trying to find out a way to clear python console. Not just any solution is
suitable, but it must be exactly same result as pressing Ctrl+L.

From other threads I have already tried several options:

    
    
    >>> import os
    >>> os.system('clear')
    256
    
    >>> import subprocess
    >>> subprocess.call("clear", shell=True)
    1
    
    >>> print '\n'*1000
    

As you can see neither `os.system('clear')` nor `subprocess.call("clear",
shell=True)` produce desired result. They just output a value (256 or 1
respectively). `print '\n'*1000` is so far closest the desired outcome.
However, there are two issues with it:

  1. the cursor is not at the top of the screen (as Ctrl+L does), but it stays at the bottom, so all new lines printed by my code are being scrolled upwards, which makes it impossible to read.
  2. the visual experience is highly dependent on the value, so in order to make it somewhat readable I have to use `print '\n'*100000` instead

Does anyone know the right solution, the one that can really do Ctrl+L from
the command line? (yes I am using linux, and I have no interest in windows
solutions)


Answer: You can try:

    
    
    os.system('tput reset')
    

To hide the return value, use:

    
    
    variable = os.system('tput reset')
