Within a Python script, a line that states print (var) outputs the following:
[{'1' : 'CentOS', '2' : 'Ubuntu'}, {'1' : 'Windows 10', '2' : 'Windows Server 2016'}]
Which of the following objects or data structures is var?
Within a Python script, a line that states print (var) outputs the following:
[{'1' : 'CentOS', '2' : 'Ubuntu'}, {'1' : 'Windows 10', '2' : 'Windows Server 2016'}]
Which of the following objects or data structures is var?
The output is a list because it is an ordered collection of elements enclosed within square brackets, with each element separated by a comma. The elements within this list are dictionaries, as indicated by the curly braces. In Python, a list can contain various types of elements, including dictionaries, which makes it the appropriate data structure for the given output.
The output of print(var) is a list of two dictionaries. The first dictionary has keys '1' and '2', and their corresponding values are 'CentOS' and 'Ubuntu', respectively. The second dictionary has keys '1' and '2', and their corresponding values are 'Windows 10' and 'Windows Server 2016', respectively. Therefore, the correct answer is D. A list.
A list is an ordered data structure with elements separated by a comma and enclosed within square brackets. list = [1, 2, 3, 4, 5] list = ['cat', 'dog', 'horse']
D. A list Explanation: A. An array: In Python, arrays are not a native data structure (they are typically provided by the array module or libraries like NumPy). This structure looks more like a list. B. A class: The output does not represent an instance of a class. It lacks attributes or methods typical of class instances and is formatted as a list of dictionaries. C. A dictionary: The entire structure is not a dictionary. Instead, it contains dictionaries within another structure.
The output provided is a list containing two dictionaries as its elements. Each dictionary represents a set of key-value pairs, where the keys are '1' and '2', and the values are operating system names. Therefore, the variable var is a list.
