How to clear the interpreter console?

Question

Like most Python developers, I typically keep a console window open with the Python interpreter running to test commands, dir() stuff, help() stuff

Answer 1

Here's the definitive solution that merges all other answers. Features:

1. You can copy-paste the code into your shell or script.

2. You can use it as you like:

   >>> clear()
   >>> -clear
   >>> clear  # <- but this will only work on a shell
   

3. You can import it as a module:

   >>> from clear import clear
   >>> -clear
   

4. You can call it as a script:

   $ python clear.py
   

5. It is truly multiplatform; if it can't recognize your system
   (ce, nt, dos or posix) it will fall back to printing blank lines.

Or if you are just looking for the code:

class clear:
 def __call__(self):
  import os
  if os.name==('ce','nt','dos'): os.system('cls')
  elif os.name=='posix': os.system('clear')
  else: print('\n'*120)
 def __neg__(self): self()
 def __repr__(self):
  self();return ''

clear=clear()
