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:
- 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.
- the visual experience is highly dependent on the value, so in order to make it somewhat readable I have to use
print '\n'*100000instead
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)
回答1:
You can try:
os.system('tput reset')
To hide the return value, use:
variable = os.system('tput reset')
