Why not use a fricking class framework:
class Endpoint:
def __init__(self, value):
self.value = value
class IncludedEndpoint(Endpoint):
def above(self, x):
return x > self.value
def below(self, x):
return x < self.value
class ExcludedEndpoint(Endpoint):
def above(self, x):
return x >= self.value
def below(self, x):
return x <= self.value
class Range:
def __init__(self, lower_bound, upper_bound):
self.lower_bound = lower_bound
self.upper_bound = upper_bound
def outside(self, x):
return self.lower_bound.below(x) or self.upper_bound.above(x)
def inside(self, x):
return not self.outside(x)
Then, we could simply have:
if Range(IncludedEndpoint(0), IncludedEndpoint(10)).outside(x):
print("x has wrong value")
else:
print("x has good value")
Just for the sake of readability, I mean...
