    3.  Surf the Internet and find more information about features of Python.

                          4.  Competency-based/Application-based questions:
                             a.   Aryan has written the following code to perform the multiplication of two numbers and print the
                                result:

                               x, y == 10, 20
                               z = x * y
                              print(z)
                                Do you think the code is correct? Why or why not?

                             b.  Lara has taken two numbers as input by using the following statements:
                                x = input("Enter the first number")

                               y = input("Enter the second number")
                                  But when she tries to perform the addition operation, she gets a concatenation of numbers. Why
                                is she not getting the correct output?

                             c.   Jiva is working on a scientific research  project in which she has to calculate the
                                population growth of the bacteria over multiple time intervals. The population of
                                the bacteria doubles every hour under ideal conditions. Which  python  operator
                                should she use to get the desired result?
                             d.   Leena is writing some logical expressions in which she wants to reverse the result of a logical
                                expression. Which Python operator she can use to achieve this?

                    Subject  Coding
                     Write a Python program to:
                     1.  calculate the value of the following expression if a = 5, b = 3, and c = 7:
                         (a * b) + (c // a) - (b % c)
                     2.  check whether X is greater than Y and the sum of these two numbers is even.
                     3.  combine the following words and display in one line with a single space:
                         Python
                         Programming
                         Language
                     4.  input five numbers and display their average.
                     5.  convert inches into centimetre.
                     6.  convert Celsius to Fahrenheit using the formula: (Celsius * 1.8) + 32
                     7.   convert kilometre unit to metre

                  For The Teacher
                      Discuss about Python programming modes with the students.
                      Go through all the other topics covered in this chapter.
                      Tell the students about the importance of Python.
