WGU D522 Python for IT Automation OBJECTIVE ASSESSMENT PRACTICE EXAM QUESTIONS WITH CORRECT DETAILED ANSWERS | ALREADY GRADED A+RECENT VERSION 1) How can multiple Python variables of different types be output using the print() function? - ANSWER By separating each variable with a comma 2) What is the scope of a variable that is defined inside a function in Python? - ANSWER Local Scope 3) How can a global variable be created inside a function in Python? - ANSWER By declaring the variable with the 'global' keyword 4) What is a characteristic of Python as a dynamically-typed language? - ANSWER The interpreter determines the type of variable during runtime 5) Which Python data type represents an ordered, mutable sequence? - ANSWER 'list' 6) What are the 3 sequence types in Python? what do they represent/look like? - ANSWER list: Ordered, mutable sequence; [1,23] tuple: Ordered, immutable sequence; (1,2,3) range: represents a range of values; e.g. range(5) 7) What are the characteristics of a set? - ANSWER Unordered, mutable collection of unique elements. {1,2,3} 8) what is a dictionary mapping type? - ANSWER an unordered collection of key-value pairs. my_dict = {'key':'value', 'name':'John'} 9) What happens when an operation is performed that involves both an int and a float in Python? - ANSWER the result is automatically promoted to a 'float' 10) What does the 'round(x, n) function do in Python? - ANSWER it rounds 'x' to 'n' decimal places 11) What are the two main escape characters? - ANSWER n : new line t : for a tab 12) What are the 3 components of a string slice? - ANSWER string [start:stop:step] · Start: the index from which the slicing begins (inclusive) · Stop: the index at which the slicing ends (exclusive) · Step (optional): The step or stride between characters. 13) What does the string slicing operation 'text {::-1] do where text = "Hello, Python!"? - ANSWER It reverses the string. The 'step' portion of the slice is negative, indicating the stride between characters is reversed. 14) What does the 'strip()' method do in Python? - ANSWER It removes leading and trailing whitespaces from a string 15) what does the += operator do in Python string manipulation? - ANSWER It is used as a shorthand for concatenation and assignment 16) What are truthy and falsy values in Python? - ANSWER Truthy values are non-zero numbers and non-empty strings. Falsy values are zero, None, and empty strings 17) What is the purpose of the // operator in Python? - ANSWER It performs floor division operation; performs division and rounds down to the nearest whole number and discards the decimal part 18) What does the pop() method do? - ANSWER It removes an item at the specified index position. example: devices = ['router1', 'switch2', 'firewall3'] removed_ device = devices. pop(1) 19) This removes 'switch2' from devices since it is in index 1 position, and now it added to "removed _device. 20) What is a 'shallow copy' of a list in Python? - ANSWER A copy of the list where changes to the copied list do not affect the original list. 21) What is the difference between using the '+' operator and the 'extend()' method to concatenate lists in Python? - ANSWER The '+' operator creates a new list, while the 'extend()' method adds elements to the end of the original list. 22) What is a significant advantage of using tuples in Python for storing information about network devices? - ANSWER tuples can be used as keys in dictionaries due to their immutability. 23) How are items in a tuple accessed? - ANSWER By placing the index of the item inside square brackets [] after the tuple name 24) What is the purpose of the input() function in Python? - ANSWER To capture user input and store it as a string 25) What does the format() method do in Python? - ANSWER It enhances output formatting by embedding variables in strings. (although 'f' strings are easier to read) 26) What is the purpose of the Code Editor in a Python IDE? - ANSWER To provide a text editor designed for Python, offering features like syntax highlighting, code completion, and indentation. 27) What does this built in Python function do?: print() - ANSWER outputs text or variables to the console 28) What does this built in Python function do?: input() - ANSWER reads user input from the console 29) What does this built in Python function do?: len() - ANSWER determines the length of a sequence (string, list, tuple) 30) What does this built in Python function do?: type() - ANSWER returns the type of an object 31) What does this built in Python function do?: int(), float(), str() - ANSWER converts values to integers, floats, or strings; respectively 32) What does this built in Python function do?: max(), min() - ANSWER returns the maximum or minimum value from a sequence 33) What does this built in Python function do?: sum() - ANSWER calculates the sum of elements in a sequence 34) What does this built in Python function do?: abs() - ANSWER returns the absolute value of a number 35) What does this built in Python function do?: range() - ANSWER generates a sequence of numbers 36) What does this built in Python function do?: sorted() - ANSWER returns a sorted list from an iterable 37) What does this built in Python function do?: any(), all() - ANSWER checks if any or all elements in an iterable are true 38) What does this built in Python function do?: map(), filter() - ANSWER applies a function to elements or filters elements based on a function 39) What does this built in Python function do?: open(), read(), write() - ANSWER handles file I/O operations 40) What does this built in Python function do?: dir() - ANSWER lists the names in the current scope or attributes of an object 41) What does this built in Python function do?: help() - ANSWER provides help information about an object or Python 42) What is the primary characteristic of Python variables? - ANSWER Variables are created as soon as a value is assigned to them. 43) What are the 5 Variable name rules in Python? - ANSWER 1. can only contain letters, numbers, or an underscore. 2. MUST start with either a letter or underscore 3. Cannot start with a number 4. Cannot contain special characters. 5. Cannot be a Python keyword (such as: and, as, def, else, etc) 44) What are the traits of Imperative/procedural programming? - ANSWER Focuses on describing a sequence of steps to perform a task 45) What are the traits of Object-Oriented Programming (OOP)? - ANSWER Organize code around objects, which encapsulate data and behavior. 46) What are the traits of Functional Programming? - ANSWER emphasizes the use of functions and immutable data for computation. 47) What are the traits of Declarative Programming? - ANSWER describes what the program should accomplish without specifying how to achieve it. 48) What are the traits of Event-Driven Programming? - ANSWER Reacts to events and user actions, triggering corresponding functions. 49) What are the traits of Logic Programming? - ANSWER defines a set of logical conditions and lets the system deduce solutions. 50) What does Python syntax refer to? - ANSWER The set of rules that dictate the combinations of symbols and keywords that form valid Python programs 51) What is the purpose of indentation in Python? - ANSWER To define blocks of code 52) Why might a programmer use comments for 'Preventing Execution'? - ANSWER To temporarily disable lines or blocks of code 53) What is the primary use of whitespace in Python? - ANSWER To define the structure and hierarchy of the code 54) What does Python use to define the scope of control flow statements and structures like functions and classes? - ANSWER Indentation 55) What happens if the number of variables is not equal to the number of values in a Python assignment statement? - ANSWER An error will occur 56) What does unpacking involve in Python? - ANSWER Extracting elements from iterable objects and assigning them to individual variables 57) What is the result of using the '+' operator to output multiple Python variables of different types? - ANSWER A Python error occurs. (must use variables of the same type)
