What is cohesion in Python?
Cohesion is a tool for measuring Python class cohesion. In computer programming, cohesion refers to the degree to which the elements of a module belong together. Thus, cohesion measures the strength of relationship between pieces of functionality within a given module.
Is the best type of module cohesion?
Which of the following is the best type of module cohesion? Explanation: Functional Cohesion is a type of cohesion in which the tasks performed by a software module all contribute to the performance of a single function.
Which is not a cohesion metric?
LCOM4 is the lack of cohesion metric we recommend for Visual Basic programs. LCOM4 measures the number of “connected components” in a class. A connected component is a set of related methods (and class-level variables).
Why is low cohesion bad?
Cohesion represents the degree to which a part of a code base forms a logically single, atomic unit. It can also be put as the number of connections inside some code unit. If the number is low, then the boundaries for the unit are probably chosen badly, the code inside the unit is not logically related.
What is cohesion in OOP?

How many type of cohesion are there in software design?
Why high cohesion is required?
Advantages of high cohesion (or “strong cohesion”) are: Reduced module complexity (they are simpler, having fewer operations). Increased system maintainability, because logical changes in the domain affect fewer modules, and because changes in one module require fewer changes in other modules.
