Try playing around in this python tutor link for answering the questions.

1) What is the total number of objects that were referenced by the variables in the given code during the execution?

2) What is the total number of objects that were referenced by the variables in the given code at the end of the execution?

3) What is the total number of variables refering to the same object as variable b (including b) at the end of the execution of the given code?

4) Select the variable(s) that are refering to the same object as a at some point of time during the execution of the above code.

5) Assume s is a str, if the output of print(s) is The next line char is \\n, then select the possible the value(s) of s.

"""The next line char is \\n"""

"The next line char is \\\\n"

'The next line char is \\n'

'The next line char is \\\\n'

6) Assume s is a str, if the output of print(s) is given below.

GrPA 1 Numbers (Arithemetic) Graded 👨‍💻 QUESTIONTEST CASESSOLUTION Change in eligibility criteria to write oppe1 exam: A1>=40/100 AND A2>=40/100 AND A3>=40/100 AND A4>=40/100

GrPA 1 While Loop Graded 👨‍💻 QUESTIONTEST CASESSOLUTION Instructions Question ❓ Implement different parts of a multi-functional program based on an initial input value. Each part of the program will handle various tasks related to accumulation, filtering, mapping, and combinations of these operations. None of the tasks should use explicit loops for definite repetitions, and the program should handle indefinite inputs gracefully.

GrPA 2 For Loop Graded 👨‍💻 QUESTIONTEST CASESSOLUTION Instructions Question ❓ Write a multi functional program that takes input task from standard input and does the corresponding taks accordingly. Note that the useage of for loop is not allowed in this exercise.

GrPA 3 Nested Loops Graded 👨‍💻 QUESTIONTEST CASESSOLUTION Instructions Question ❓ Create a multi-functional program that performs different tasks based on the user input. The program should support the following tasks:

GrPA 4 Loops Application Graded 👨‍💻 QUESTIONTEST CASESSOLUTION Instructions Question ❓ You are tasked with writing a program that can handle various tasks based on the input. The first line of the input represents the task to be performed. The possible tasks are:

Multiple Choice Questions 🧠 1) What will be the output type of the expression 5 + 2? int float str bool Invalid Expression (raises an error) 2) What will be the output type of the expression 5 + 2.0?

Multiple Choice Questions 🧠 1) Select the correct implementation of a program that accepts a positive integer x as input and prints the maximum value of the integer y such that $2^y \leq x$. Sample Test Cases Input Output 100 6 256 8 Select all correct implementations of the program. (MSQ) 1 2 3 4 5 6 x = int(input()) y = 0 while x > 1: x = x // 2 y = y + 1 print(y) 1 2 3 4 5 6 x = int(input()) y = 0 while x >= 1: x = x // 2 y = y + 1 print(y) 1 2 3 4 5 6 x = int(input()) y = 0 while x > 1: x = x / 2 y = y + 1 print(y) 1 2 3 4 5 6 x = input() y = 0 while x > 1: x = x // 2 y = y + 1 print(y) Solution The query asks to identify the correct Python implementation for a program that accepts a positive integer x as input and prints the maximum integer y such that $2^y \leq x$.
