Cohesion refers to the degree to which the elements within a module belong together.
High cohesion is generally associated with good software design.

st.write("""
1. **Functional Cohesion**: All elements of the module are related to the performance of a single function.
2. **Sequential Cohesion**: Elements of a module are involved in activities where output from one element serves as input to another.
3. **Communicational Cohesion**: Elements of a module operate on the same data.
4. **Procedural Cohesion**: Elements of a module are involved in different and possibly unrelated actions that must be performed in a specific order.
5. **Temporal Cohesion**: Elements are related by the fact that they are processed at a particular time in program execution.
6. **Logical Cohesion**: Elements perform similar operations, but these operations are unrelated.
7. **Coincidental Cohesion**: Elements have no meaningful relationship to one another.
