2. Subtraction Operator. In Python, scalar subtraction can be performed with the operator -.

In the exercise below, start by defining two variables, a=7 and b=8.

Next, subtract a from b, and assign the difference to a third variable, c.

Finally, use the print() function to print c to the console.


                                  
                                      # Define a and b.
                                      a = ___
                                      ___ = ___
                                  
                                      # Subtract a from b.
                                      c = ___
                                  
                                      # Print c.
                                      print(___)


                                  
                                      # Define a and b.
                                      a = 7
                                      b = 8
                                  
                                      # Subtract a from b.
                                      c = b - a
                                  
                                      # Print c.
                                      print(c)


                                      test_object("a")
                                      test_object("b")
                                      test_object("c")
                                      success_msg("Correct! Notice that - can also be used to perform elementwise subtract between numpy arrays.")

You can use the - operator to subtract one number from another.
