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
|
