Operators is and is not check if their operands point to the same instance, thus
they will always return respectively False and True when they are used to compare objects of different types.
Code examples
Noncompliant code example
a = 1
b = "1"
value = a is b # Noncompliant. Always False
value = a is not b # Noncompliant. Always True
Compliant solution
a = 1
b = 1
value = a is b
value = a is not b
