Assertion and Reasoning Based Questions

The following questions are assertion(A) and reasoning(R) based. Mark your answer as
a. Both A and R are true and R is the correct explanation of A
b. Both A and R are true and R is not the correct explanation of A
c. A is true but R is false
d. A is false but R is true
1. Assertion(A): Python considers user input as strings
Reasoning(R): An INPUT() is used to accept user input from the keyboard.
2. Assertion(A): Comments make the program lengthier.
Reasoning(R): Comments are ignored by the Python interpreter during execution.
3. Assertion(A): An operator specifies the operation to be performed on the given operands.
Reasoning(R): An operand may be a constant or a variable.
4. Assertion(A): Evaluating the following expression:
max('Anshul', 'Mridula', 'Shekhar', 'Ashish')
will yield 'Shekhar'.
Reasoning(R): max() takes only numeric values as arguments.
5. Assertion(A): Python allows the conversion of data from one data type to another.
Reasoning(R): int() is an example of a type conversion function.

Case-based Questions

1. Zorawar likes to work with numbers. He has just started working in Python and wants to perform the following mathematical
operations using a Python program. He wants to accept two numbers and display their sum, difference, product, quotient,
and remainder. Help him complete his task.
2. Anish is a very naughty boy. His friend, Shankar wrote a program to accept 5 numbers and display each one of them in a
single line, separated by a '$' symbol. The program is as follows:
num1 = int(input('Enter a number'))
num2 = int(input('Enter a number'))
num3 = int(input('Enter a number'))
num4 = int(input('Enter a number'))
