This is a python exercise !!


        import numpy as np
        x = np.arange(0, 5, 0.1);
        y = np.sin(x)
        print(x)
        print(y)

Just press 'Run'.


        # This will get executed each time the exercise gets initialized
        b = 6


        # Create a variable a, equal to 5


        # Print out a


        # Create a variable a, equal to 5
        a <- 5

        # Print out a
        print(a)


        test_object("a")
        test_function("print")
        success_msg("Great job!")

Use the assignment operator (<-) to create the variable a.
