                Writing to a python subprocess pipe
              
          
        
      
        
  
      
    Here's a few things I tried to write output to a python subprocess pipe.
from subprocess import Popen, PIPE

p = Popen('less', stdin=PIPE)
for x in xrange(100):
    p.communicate('Line number %d.\n' % x)
