However, if you *REALLY* want to have that sort of C++ syntax,
you can get it in Python with something like: 
"""
endl = '\n'
class OutStream:
	def __init__( self, file ):
		if hasattr( file, 'write' ):
			self.file = file
		else:
			self.file = open( file, 'w' )
	def write( self, what ):
		self.file.write( what )
	def close( self ):
		self.file.close()
	def __lshift__(self, what ):
		self.write( str(what)+' ')
		return self
import sys
out = OutStream( sys.stdout )
out << "Hello" << "World" << endl 
out << "The answer is" << 3+4 << endl
