Which characteristic of procedural programming contributes most significantly to the 'spaghetti-code' effect in large projects?
Which characteristic of procedural programming contributes most significantly to the 'spaghetti-code' effect in large projects?
- Heavy reliance on global variables and unstructured control flow. (correct)
- Tendency for localized control flow with minimal use of function calls.
- Emphasis on data structures over algorithms.
- Strict enforcement of modularity and abstraction.
How does immutability affect the behavior of tuples when used as keys in a dictionary?
How does immutability affect the behavior of tuples when used as keys in a dictionary?
- It prevents tuples from being used as dictionary keys.
- It allows tuples to be used as dictionary keys because their hash values remain constant. (correct)
- It requires tuples to be explicitly cast to a mutable type before being used as keys.
- It allows modification of the tuple's elements, affecting the corresponding value in the dictionary.
What distinguishes the use of curly braces in dictionaries from their use in sets in Python?
What distinguishes the use of curly braces in dictionaries from their use in sets in Python?
- Dictionaries use curly braces to define immutable elements only, while sets do not have this restriction.
- Sets use curly braces to define the order of elements, while dictionaries do not.
- Dictionaries use curly braces only for defining keys, while sets use them for values.
- Dictionaries use curly braces to enclose key-value pairs, while sets use them to enclose single elements. (correct)

Study Notes
- Procedural programming's major limitation is that large programs tend to turn into "spaghetti-code".
- Tuples cannot be changed like lists.
- Dictionaries are enclosed by curly braces
({}), and values are assigned and accessed using curly braces({}). - POP (Procedural Oriented Programming) is suitable for small tasks only.
- Python implements object-oriented programming.
Python Sets
- Python Sets are not indexed.
- Python Sets are changeable.
- Python Sets do not allow duplicate values.
- Python Sets are not ordered.
Python Tuples
- Python Tuples are not changeable.
- Python Tuples allow duplicate values.
- Python Tuples are indexed.
- Python Tuples are ordered.
- Implementing data as a tuple guarantees that it remains write-protected if the data shouldn't change.
- A class can be used to create many objects.
- Each key in a dictionary data type is not separated from its value by a semicolon (;).
Procedural Programming
- Procedural programming does not implement real-world entities like objects, hiding, and inheritance.
Python Dictionaries
- Python Dictionaries are changeable.
- Python Dictionaries do not allow duplicate keys.
- Python Dictionaries are not ordered.
- Python Dictionaries are indexed by keys.
- The
remove()method in set will raise an error if the item to remove does not exist. - Object-Oriented Programming (OOP) is about creating "objects".
- The OOP approach provided the solution to the limitations of the procedural programming.
- Object-Oriented Programming is not only based on the concept of methods and functions.
- In OOP, it is easier to model real-world objects, represented as objects in the program code.
Python Lists
- Python Lists are changeable.
- Python Lists allow duplicate values.
- Python Lists are indexed.
- Python Lists are ordered.
- Once a set is created, items cannot be changed, but new items can be added.
- Values are unique within a dictionary, while keys are not.
- An element with an index equal to -1 is the last one in the list.
- Simula was the first programming language with object-oriented programming features.
