Description:
Python is a popular programming language used for a myriad of applications due to its simplicity and versatility. Beginners in Python must grasp some fundamental concepts before deep diving into the advanced topics.
This content cuts through selected topics, including slicing tuples in Python, dictionary operations, loops, OOP basics, and attribute definition in classes.
In the first section, learners will interact with slicing tuple concepts. They will answer questions involving slicing at different intervals in a tuple. In the second section, the questions target dictionaries, and learners will understand how they uniquely identify each of its elements.
The third section covers loops, the different types of loops, and their applications in Python programming. It includes how ‘for loop’ works and when to use ‘while loop’ and ‘do-while loop’.
In the fourth section, learners will grasp the basics of OOP and understand what variables and methods are in OOP Python. Here they will learn what an attribute is and its definition while defining classes.

Objectives: Students will be able to understand the basic concepts of Python programming language, including tuples, dictionaries, loops, and object-oriented programming.

Learning Outcomes:
1. Students will be able to understand how to access specific elements within tuples using index values.
2. Students will be able to use negative index values to access specific elements within tuples.
3. Students will be able to understand how dictionaries use keys to uniquely identify each element.
4. Students will be able to differentiate between lists and dictionaries in terms of their ability to hold elements of different data types.
5. Students will be able to understand how dictionaries can be accessed using both names and index values.
6. Students will be able to recognize the difference between for, while, do-while loops, and switch statements.
7. Students will be able to understand the concept of attributes in object-oriented programming.
8. Students will be able to differentiate between functions and methods in object-oriented programming.
9. Students will be able to understand the significance of the double underscore prefix when defining a class attribute.

Answers:
1. Output of print(tuple[2:]) is (2.23, ‘john’, 70.2)
2. Output of print(tuple[-3:]) is (2.23, ‘john’, 70.2)
3. When referencing the first index value within a list, in reference to the last elements position, we begin with an index of: -1
4. Dictionaries use keys to uniquely identify each of its elements.
5. False. Unlike lists, a dictionary can hold elements of different data types.
6. True. Dictionaries can be accessed using names or index values.
7. While loop.
8. Attribute.
9. Method.
10. The double underscore prefix means that the variable is private and cannot be seen by outside code.

Solution 1:

Question 1: What is the output of print(tuple[2:]) if tuple = ( ‘abcd’, 786 , 2.23, ‘john’, 70.2 )?
The output of print(tuple[2:]) would be (2.23, ‘john’, 70.2), as it prints all the elements starting from the third element till the end of the tuple.

Question 2: What is the output of print(tuple[-3:]) if tuple = ( ‘abcd’, 786 , 2.23, ‘john’, 70.2 )?
The output of print(tuple[-3:]) would be (2.23, ‘john’, 70.2), as it prints the last three elements of the tuple.

Question 3: When referencing the first index value within a list, in reference to the last elements position, we begin with an index of:
We begin with an index of -1 when referencing the first index value within a list in reference to the last element’s position.

Question 4: Dictionaries use what to uniquely identify each of its elements.
Dictionaries use keys to uniquely identify each of its elements.

Question 5: Unlike lists, a dictionary can only hold elements of the same data type.
False. A dictionary can hold elements of different data types unlike a list.

Solution 2:

Question 6: Dictionaries, while normally use names to reference an element, can also use index values.
False. Dictionaries use keys to reference an element rather than index values.

Question 7: When we want our program to re-cycle after each use, that is, continue running until the user chooses to stop, we use a:
When we want our program to re-cycle after each use, that is, continue running until the user chooses to stop, we use a while loop.

Question 8: In OOP with Python, when a variable belongs to an object, we refer to it as a:
When a variable belongs to an object in OOP with Python, we refer to it as an attribute.

Question 9: In OOP with Python, when a function belongs to an object, we refer to it as a:
When a function belongs to an object in OOP with Python, we refer to it as a method.

Question 10: When defining a class’s attributes, what does the double underscore prefix mean?
The double underscore prefix means that the variable is private and cannot be seen by outside code. It is also known as name mangling.
