Introduction To Python — Part 2 MCQs with Explanations

In Python, the boolean value False evaluates to 0 in numeric contexts. The max() function returns the largest of the given arguments. Here, we have the expression max(False, -3, -4) . Since False is equivalent to 0 , and -3 and -4 are numeric values, the largest value among them is 0 . Therefore, the output of max(False, -3, -4) is False . The min() function then evaluates min(False, 2, 7) , and since False evaluates to 0 and 2 and 7 are greater than 0 , the minimum value among them is False . Hence, the overall output is False .

The len() function returns the number of items in an object. Here, we have a list ["hello", 2, 4, 6] . The list contains 4 items: a string, two integers, and another integer. Therefore, the output of len(["hello", 2, 4, 6]) will be 4 .

In Python, the core data types include: 1. Tuples 2. Lists 3. Dictionary However, Classes are not considered a core data type in Python. Classes are used to create user-defined data structures that bundle data attributes and methods. Therefore, the correct option is Option C: Class .

In Python, keywords are reserved identifiers that have special meanings and purposes within the language. eval is not a keyword in Python; rather, it is a built-in function used to evaluate a Python expression stored in a string. Keywords like pass , assert , and nonlocal have specific meanings in Python and are reserved for special purposes within the language. Therefore, the correct option is Option B: eval .

In the given code, the variable x is assigned a list containing two sublists: [[0], [1]] . The map() function is used to apply the str() function to each element of x , converting them to strings. Then, list() is used to convert the resulting map object to a list. The join() function concatenates these strings with a space separator. Finally, the result is enclosed in a tuple using (...) and printed. Therefore, the output will be: ('[0] [1]',) .

In the given code, the function foo() is defined. Inside the function, there is a try-finally block. In the try block, return 1 is encountered. However, before returning, the finally block executes, which contains return 2 . As per the behavior of finally , it always executes, regardless of whether there is an exception or not. Therefore, the return 2 statement in the finally block is executed, and 2 is returned from the function. When foo() is called and its return value is assigned to k , k will be 2 . Hence, the output will be 2 .

In Python, to add a new element to the end of a list, the append() method is used. The syntax for using append() is list_name.append(element) , where list_name is the name of the list and element is the value to be added. append() adds the specified element to the end of the list, increasing the list's length by one. Therefore, list1.append(5) will add the element 5 to the end of list1 .

The program defines a function f that takes another function x as an argument. Inside f , there is a nested function f1 defined with variable-length arguments *args and keyword arguments **kwargs . The use of *args allows f1 to accept any number of positional arguments, and **kwargs allows it to accept any number of keyword arguments. Inside f1 , "Examveda" is printed, and then the function x is called with the received arguments using (*args, **kwargs) . Therefore, the program can work with any number of parameters .

In Python, there is no fixed limit on the maximum length of an identifier imposed by the language itself. Identifiers can be of any length as long as they follow the naming rules (e.g., start with a letter or underscore, followed by letters, digits, or underscores). However, extremely long identifiers are discouraged because they reduce code readability and may not be supported well by some tools or editors. Option A (79 characters) refers to the recommended maximum line length in PEP 8, not identifier length. Option B and C (31 and 63 characters) were limits in older languages like C, not Python. Therefore, the correct answer is Option D: none of the mentioned .

Explanation: The code starts with `i` initialized to 1. The `while True` loop runs indefinitely until a `break` statement is encountered. Inside the loop, the `if i%3 == 0:` condition checks if `i` is divisible by 3. If `i` is divisible by 3, the `break` statement will terminate the loop. If `i` is not divisible by 3, the value of `i` is printed. Then, there's an error `i += 1` it should be not `i + = 1`. So the correct answer is Option B: error
