Python 3: Project-based Python, Algorithms, Data Structures - While loops, enumerate, zip

The video tutorial covers the implementation and enhancement of the Dunder STR method in Python, allowing custom string representations of objects. It explains how to capitalize names and format course lists using the join function. The tutorial also explores special methods like Len and RPR, highlighting their differences and uses. Finally, it introduces the concept of storing objects in files for future retrieval.

What is the purpose of the Dunder STR method in Python?

• To initialize an object

• To provide a string representation of an object

• To delete an object

• To compare two objects

How can you customize the string representation of an object in Python?

• By modifying the Dunder init method

• By using the print function

• By overriding the Dunder STR method

• By using the Dunder repr method

Which function is used to capitalize the first letter of a string in Python?

• upper()

• lower()

• capitalize()

• title()

What does the join function do in Python?

• Splits a string into a list

• Finds a substring in a string

• Combines elements of a list into a string

• Reverses a string

How does the map function work in Python?

• It sorts elements of an iterable

• It applies a function to each element of an iterable

• It filters elements of an iterable

• It reverses elements of an iterable

What does the DIR function return when used on an object?

• The size of the object in bytes

• A list of all attributes and methods of the object

• The memory address of the object

• The type of the object

What is the output of the Dunder dict method?

• A string representation of the object

• A dictionary representation of the object

• A list of object methods

• The length of the object

What does the Dunder Len method return for a student object?

• The number of students

• The number of courses the student is enrolled in

• The length of the student's name

• The total number of attributes in the student object

What is the purpose of the Dunder RPR method?

• To provide a user-friendly string representation of an object

• To provide a developer-friendly string representation of an object

• To delete an object

• To initialize an object

What happens if the Dunder STR method is missing in a class?

• The class cannot be compared

• The class cannot be printed

• The Dunder RPR method is used for string representation

• The class cannot be instantiated
