This is my goat, ... whose name is Adam.''' >>> >>> result = pysed.replace(text, 'This', 'THIS') >>> >>> print result THIS is my cat, whose name is Betty. THIS is my dog, whose name is Frank. THIS is my fish, whose name is George. THIS is my goat, whose name is Adam. >>> >>> result = pysed.replace(text, 'max=2/This', 'THIS/red') >>> >>> print result THIS is my cat, whose name is Betty. THIS is my dog, whose name is Frank. This is my fish, whose name is George. This is my goat, whose name is Adam. >>> >>> result = pysed.append(text, 'max=1/cat', ' >>> /green') >>> >>> print result This is my >>>cat, whose name is Betty. This is my dog, whose name is Frank.
