Clear terminal in Python [duplicate]

Answer 1

In Windows you can use:

>>> import os
>>> clear = lambda: os.system('cls')
>>> clear()

Answer 2

A perhaps cheesy way to clear the screen, but one that will work on any platform I know of, is as follows:

for i in xrange(0,100):
    print ""

Answer 3

What about escape sequences?

print(chr(27) + "[2J")

Answer 4

Just use:

print("\033c")

This will clear the terminal window.

Answer 5

Came across this some time ago

def clearscreen(numlines=100):
  """Clear the console.
numlines is an optional argument used only as a fall-back.
"""
# Thanks to Steven D'Aprano, http://www.velocityreviews.com/forums

  if os.name == "posix":
    # Unix/Linux/MacOS/BSD/etc
    os.system('clear')
  elif os.name in ("nt", "dos", "ce"):
    # DOS/Windows
    os.system('CLS')
  else:
    # Fallback for other operating systems.
    print('\n' * numlines)

Then just use clearscreen()

Answer 6

I would do it in this way to make it look more like bash:

Just create a file named .pythonstartup at Home directory and use poke's answer in a function

On Linux:

echo "from subprocess import call
def clear(int=None):  
    call('clear')
    if int == 0:
       exit()
clear()" >> $HOME/.pythonstartup ; export PYTHONSTARTUP=$HOME/.pythonstartup ; python

You can add export PYTHONSTARTUP=$HOME/.pythonstartup to your ./bashrc file

Since what I care about is space; a call to the function will not display the python interpreter description at startup, but you can remove clear() to retain it.

Using it like a normal function should do the trick without printing the exit status:

>>> clear()

If you pass the argument 0 to the function it will clear the screen and exit successfully so you can continue using the shell in a clean screen

>>> clear(0)
