That's true with this example, but is:
lines = [
"Developments in high-speed rail, and high-speed",
"transport more generally, have historically been",
"impeded by the difficulties in managing friction",
"and air resistance, both of which become",
"substantial when vehicles approach high speeds.",

"type of system from ever being built. The",
"Hyperloop can be viewed as a modified vactrain,",
"employing more cost-effective solutions to the",
"same problems the latter was designed to solve."
]
really more readable than:
lines = """\
Developments in high-speed rail, and high-speed
transport more generally, have historically been
impeded by the difficulties in managing friction
and air resistance, both of which become
substantial when vehicles approach high speeds.
The vactrain concept eliminates these obstacles
by employing magnetically levitating trains in
tubes kept at a complete vacuum, allowing for
heoretical speeds of thousands of miles per
hour. The high cost of constructing such a system,
however, and the difficulty of maintaining a
vacuum over large distances, has prevented this
type of system from ever being built. The
Hyperloop can be viewed as a modified vactrain,
employing more cost-effective solutions to the
same problems the latter was designed to solve.
"""[1:-1].split("\n")
?
Additionally,namedtuple has already set the precedence for this kind of thing.
Finally, a simple extension or a decent editor should make it trivial
to convert between the forms, so you can write the shorter way and
convert on-the-fly.
