Pemrograman Python Quiz ( Session IV - VI)

What is a data structure?

• A type of programming language

• A specialized way of organizing data

• A method for data retrieval

• A way to store images

Answer explanation

A data structure is a specialized way of organizing data to enable efficient access and modification. This definition aligns with the correct choice, emphasizing the importance of organization in handling data.

What does a data element refer to?

• An individual entity in a data structure

• A collection of data

• A type of data structure

• A programming language feature

Answer explanation

A data element is defined as an individual entity within a data structure, representing the smallest unit of data.

What is a data attribute?

• An individual data element

• A type of data structure

• A programming concept

• Characteristics of a data element

Answer explanation

A data attribute refers to the characteristics of a data element, describing its properties and qualities. This distinguishes it from being just an individual data element or a programming concept.

What is a list in Python?

• A sequence of mutable data

• A type of dictionary

• An immutable data structure indexed by an integer number

• A collection of unique elements

Answer explanation

A list in Python is a sequence of mutable data and indexed by an integer number. Meaning its elements can be changed after creation.

What is the purpose of the sort() method in lists?

• To modify the list in-place

• To return a new sorted list

• To clear the list

• To add items to the list

Answer explanation

The sort() method modifies the list in-place, meaning it changes the original list rather than creating a new one. While sorted() function returns a new sorted list, leaving the original list unchanged.

What is the order for each data type when sorting in Python?

• Boolean

  Strings

  Numbers

• Boolean

  Numbers

  Strings

• Numbers

  Boolean

  Strings

• Strings

  Boolean

  Numbers

Answer explanation

In Python, the default sorting behavior follows a "natural" comparison order for different data types. First, numerical values (both integers and floats) are compared. Next, boolean values are sorted, with False being treated as smaller than True. After that, strings are sorted alphabetically, where uppercase letters are considered smaller than lowercase letters, resulting in the order: A-Z preceding a-z.

What output will be produced from this code?

• {'apple': 1, 'banana': 2, 'cherry': 3, 'dragonfruit': 5}

• {'apple': 1, 'dragonfruit': 5, 'cherry': 3}

• {'apple': 1, 'cherry': 3, 'dragonfruit': 5}

• {'apple': 1, 'banana': 2, 'dragonfruit': 5, 'cherry': 3}

Answer explanation

• We iterate through my_dict and add each key-value pair to new_dict.

• When we encounter 'banana', we insert the new key-value pair ('dragonfruit': 5).

• The remaining items are added afterward, preserving the order we want.

What output will be produced from this code?

• [5, 3, 5, 7, 9]

• [1, 5, 5, 7, 9]

• [9, 7, 5, 5, 1]

• [9, 7, 5, 3, 5]

Answer explanation

The value at index 1 of my_list is changed from 3 to 5, resulting in the list [1, 5, 5, 7, 9]. Then my_list[::-1] creates a new list that is the reverse of my_list using slicing.

What output will be produced from this code?

• {

  'm': ['satria', 'fadhil'],

  'f': ['grace', 'naila', 'najwa', 'aulia']

  }

• {

  'm': ['satria', 'fadhil', 'tegar'],

  'f': ['grace', 'naila', 'najwa', 'aulia']

  }

• {

  'm': ['tegar', 'satria', 'fadhil'],

  'f': ['grace', 'naila', 'najwa', 'aulia']

  }

• {

  'm': ['tegar', 'satria', 'fadhil'],

  'f': ['grace', 'najwa', 'aulia', 'naila']

  }

What output will be produced from this code?

• Biomedical Engineering

• Biomaterials

• ['Anatomy', 'Biomedical Engineering']

• ['Signal Processing', 'Networking']

Answer explanation

• The code effectively demonstrates how to use nested data structures (a list containing dictionaries, with one of those dictionaries containing a list) to store and access complex data related to students.

• The specific print statement retrieves and displays the second course that the first student (Putri) is enrolled in, which is "Biomedical Engineering."
