Clearing the screen of text

Expand Post »

I can't find a simple command that does this. If there's no command that does this I'm going to spam python.org until they finally agree to put this in the next version of python.

Python.org supposedly loves spam anyway, so long as you include some eggs.

Sigh.

No, python doesn't have clear screen.

Re: Clearing the screen of text

there's not even some way to trick the computer into clearing the screen of text?

Re: Clearing the screen of text

I suggest

python Syntax (Toggle Plain Text)
>>> print("\n" * 40)
>>> print("\n" * 40)

Or even better

python Syntax (Toggle Plain Text)
>>> def clear():
...      print("\n"*40)
>>> clear()
>>> def clear():
...      print("\n"*40)
>>> clear()

Last one:

python Syntax (Toggle Plain Text)
>>> def clear():
...      import sys
...      for i in range(40):
...          print(sys.ps1)
>>> def clear():
...      import sys
...      for i in range(40):
...          print(sys.ps1)

Re: Clearing the screen of text

The last one doesn't work, says the attribute ps1 doesn't exist. But that is what I was planning to do at first, but then that leaves a big side bar. Oh well, I guess I'll just have to use the print thing.

Re: Clearing the screen of text

Clearing the display screen in console mode depends on the Operating System, that and the limited usefulness is why many multiplatform computer languages do not include it.

Here is a Python version using module os ...

python Syntax (Toggle Plain Text)
import os
# works on windows nt (also xp and vista) or linux
os.system(['clear','cls'][os.name == 'nt'])
import os
# works on windows nt (also xp and vista) or linux
os.system(['clear','cls'][os.name == 'nt'])

Re: Clearing the screen of text

python Syntax (Toggle Plain Text)
import os
# works on windows nt (also xp and vista) or linux
os.system(['<strong class="highlight">clear</strong>','cls'][os.name == 'nt'])
import os
# works on windows nt (also xp and vista) or linux
os.system(['<strong class="highlight">clear</strong>','cls'][os.name == 'nt'])

Can anyone kindly explain the background of how this bit of code works?
