The "is" operator checks object *identity*, that is, if both operands are
actually the same object. It may or may not work here, depending on many
implementation details. You really should check if they are *equal*
instead:
if c == quote:
qcount += 1
if c == sep and qcount % 2 == 0:
splitpoints.append(index)
See:
py> x='a'
py> y='A'.lower()
py> y
'a'
py> x==y
True
py> x is y
False
