Decorating Python’s sys.stdout

Posted by Codehead on November 14, 2008 at 2:17 am · Under Fun, Programming, Python

Try this:

class stdoutflip:
 
    def __init__(self, sys):
        self.stdout = sys.stdout
        sys.stdout = self
 
    def write(self, txt):
        txt = list(txt)
        txt.reverse()
        self.stdout.write(''.join(txt))
 
 
class stdoutupper:
 
    def __init__(self, sys):
        self.stdout = sys.stdout
        sys.stdout = self
 
    def write(self, txt):
        self.stdout.write(txt.upper())

To test it do this:

out = stdoutupper(stdoutflip(sys))

Now try printing stuff:

print "Hello Python!"
