Flushing sdtout

[Aaron Ginn]

Is there a simple way to flush stdout on every print statement similar
to the $| variable in perl?  Currently, I'm adding a
sys.stdout.flush() statement after every single print statement in a
script in order to write the run to a logfile, but I'd like to simply
be able to tell python to do it after every print statement without
explicitly telling it to.

Also, how can I flush the string in an input statement to stdout
before the input is provided by the user?  For example, here is a
code snippet:

	print '------------------------------'
	sys.stdout.flush()
	print '      Type of DRC run.'
	sys.stdout.flush()
	print '------------------------------'
	sys.stdout.flush()
	print '1) DRC (default)'
	sys.stdout.flush()
	print '2) Antenna DRC check'
	sys.stdout.flush()
	print 'q) quit'
	sys.stdout.flush()

	while 1:
	    selection = raw_input('Enter type of DRC to run from menu --> ')
	    sys.stdout.flush()

This prints the following to stdout:

------------------------------
      Type of DRC run.
------------------------------
1) DRC (default)
2) Antenna DRC check
q) quit

Unfortunately, it does not print the string in the raw_input statement
until the user has selected from the menu.  Thus the output looks like
this:

1
Enter type of DRC to run from menu --> 

I want the string printed to stdout before the user has to make a
selection.  Is there a way to do this?

Thanks,
Aaron
