Wrap long statements across multiple lines.

PEP 8 specifies:

* Limit all lines to a maximum of 79 characters.

* The preferred way of wrapping long lines is by using Python’s implied
  line continuation inside parentheses, brackets and braces. Long lines can
  be broken over multiple lines by wrapping expressions in parentheses.
  These should be used in preference to using a backslash for line
  continuation.
