Use split() and join() methods of strings, along with slicing.  Like this:

    fullstring = """foo
    bar
    baz"""

    sansfirstline = '\n'.join(fullstring.split('\n')[1:])

The last line does this:
1. fullstring.split('\n') turns it into a list of ['foo', 'bar', 'baz']
2. the [1:] slice removes the first element, making it ['bar', 'baz']
3. Finally, '\n'.join() turns the list into a string separated by
newlines ("""bar
baz""")
