              first-name             contains a hyphen(-)
           2.  In the expression, 5*10, identify the operator(s) and operand(s).
         Ans:   Operator:  *
              Operands:  5 and 10
           3.  Write the output that will be produced when the following instructions are executed using Python interpreter:
              (i)  >>> 12 + 30
         Ans:  42
              (ii) >>> "large" + "Box"
         Ans:  'largeBox'

              (iii) >>> "15" + "15"
         Ans:  '1515'

              (iv) >>> "20" + 20
         Ans:  TypeError
              (v) >>> 60.5 + 40.45
         Ans:  100.95
           4.  Find the error in the code given below:
              radius = 5
              area = pi * radius * radius
              print(area)
         Ans:  The name pi is not defined, so it cannot be used in the formula.
            5  What will be the output produced on execution of the following instructions by the Python interpreter?

              >>> m1, m2, m3 = 10, 20, 30
              >>> print(m1 + m2, m3 - m1, m2 * m3, sep = '***')
         Ans:  30***20***600
           6.  What will be the output produced on execution of the following instructions by the Python interpreter?

              >>> #Play with the argument: end
              >>> m1, m2, m3 = 10, 20, 30
              >>> print(m1 + m2, m3 - m1, m2 * m3, end = '***')
         Ans: 30 20 600***
           7.  Write a statement in Python to assign the value 16 to the variable age and to assign the value 'Kolkata' to the variable city.

         Ans:  age = 16
              city = 'Kolkata'
           8.  What will be the output produced on the execution of the following code segment in Python?
              num1 = num2 = 50
              Num2 = 100
              print(num1, num2)
         Ans:  50    50
           9.  What will be the output produced on the execution of the following code segment in Python?

              num1 = num2 = 50
              num2 = 100
              print(num1, num2)
         Ans:   50    100
