While it's true that split() doesn't retain the separator, you still
know what the separator is, right?  Why not do something like:

text = raw_input("Enter text: ") 
sep = 'and'
parts = text.split(sep)
for i in parts[:-1]:
    print i
    print sep
print [-1]

You might also want to consider stripping whitespace in the individual
list items, too.
