Strings

Strings ("string literals", to be precise) are enclosed in quotes (single or double).
Multi-line strings are enclosed in triple-quotes.

    'x'
    "Hello, world"
    """Twas brillig and the slithy toves
    did gyre and gimble in the wabe."""

Values can be written into a string with the % operator:

    >>> x = 1
    >>> y = 2
    >>> 'x = %d, y = %f' % (x,y)
    'x = 1, y = 2.000000'
