This looks like it's comparing them as strings. It would be wiser if
the program compared them as version-numbers:
from distutils.version import LooseVersion, StrictVersion
qt_ver = QtCore.PYQT_VERSION_STR
target_ver = "4.10"
for t, desc in [
(str, "String"),
(LooseVersion, "Loose"),
(StrictVersion, "Strict"),
]:
a = t(qt_ver)
b = t(target_ver)
print("Using %s comparison, '%r < %r' is %s" % (
desc, qt_ver, target_ver, a < b)
So the test should actually be something like
if LooseVersion(QtCore.PYQT_VERSION_STR) < LooseVersion("4.10"):
balk()
